BIOS and System Programming 4. 4.1 BIOS Description and System Programming System Structure CP486 has a firmware with basic functions for the present hardware - so called BIOS. The BIOS of the CP486 consists of several utilities: QUADTEL-BIOS: This part has usual functions for servicing of standard components of an ATcompatible computer.
BIOS and System Programming 4.2 BIOS-SETUP At the system startup the active terminal displays the BIOS version. First BIOS runs a test with different system components and then a memory test. After test completion the system tries to boot from the disk drive A, if existent, and then from disk drive C, if existent. The SETUP can be invoked only during the system startup by pressing the key. This input ensues as soon as the respective message is displayed on the screen.
BIOS and System Programming In the bank field the base address of the PLC bank can be set from 0 ... 248 in steps of 8. The specified area is activated immediately at the start up of the CP486 and is available at the PLC side. By means of the SETUP field "disk drive A" the user is able to specify further drive types (also a silicon disk) as boot drive for drive A. In order to take an effect, a floppy disk drive for A has to be selected in the second part of the SETUP.
BIOS and System Programming 4.2.2 QUADTEL-BIOS Selection Menue After leaving the VIPA-BIOS-Setup you select a menue: Modifications of the system setups in the different windows "Setup" and "Extended BIOS-Features" should be carried out only by experienced appliers. Normally, it is not necessary to modify any system setups. The menue item "System Information" informs about the applied QUADTEL-BIOS. In the menue item "System Security" a second password can be entered as a boot protection.
BIOS and System Programming 4.2.3 QUADTEL-BIOS-Setup The BIOS Setup has the following setup possibilities (shown are the default setups): In the BIOS-Setup the following system parameters can be set up: - date - time - password for system startup - type of floppy disk drive 1 (360KB, 720KB, 1.2MB, 1.44MB) - type of floppy disk drive 2 (360KB, 720KB, 1.2MB, 1.44MB) - type of the hard disk 1 (1 .. 47) - type of the hard disk 2 (1 ..
BIOS and System Programming 4.2.4 Extended BIOS-Features The Extended BIOS has the following additional features (shown are the default setups): Further system parameter can be set up in the window Extended BIOS Features. The setup should be modified only by experienced users. Normally, it is not necessary to intervene. The control keys are displayed in the lower part of the screen. By pressing the key you get help information.
BIOS and System Programming 4.2.5 AT ROM Diagnostics Almost all system components can be tested via the integrated AT ROM Diagnostics: The individual system components can be tested in the menue item "Diagnostics". The control keys are displayed in the lower part of the screen. By pressing the key you get help information. You leave the diagnostics window and return to the menue with the key.
BIOS and System Programming 4.3 4.3.1 Bit 0 Bit 1 Bit 2 System Register CP-Status Register (I/O-Address 280 hex - read only) /PLC bank interrupt 0 1 /WD reset 0 1 /PFO (accu supervision) 0 1 Bit 3 reserved status INT 12 was triggered via PLC-access to element 1023 in the current bank no access to bank element 1023 via PLC error: watchdog has announced no error CP accu voltage under 2.5V (accu empty or defective) CP accu voltage over 2.
BIOS and System Programming 4.3.
BIOS and System Programming 4.3.4 Watchdog (I/O-Address Area 270-277) The watchdog is deactivated after system startup and after reset, and can be set on and off by means of software. The watchdog must be triggered every 1.6 seconds after enabling. This triggering is realized by programming a flank. If it is not re-triggered within these 1.6 seconds, the watchdog calls a system reset (depending on CONTROL register bit 0).
BIOS and System Programming 4.3.5 Interrupt-Management Interrupt Initiation in the CP The hardware interrupt IRQ12 (software interrupt 74) on the CP486 can be initiated by PLC access to element 1023 of respectively active bank BASP activation on back plane bus The appertaining interrupt vector is filed to address 1D0 - 1D3 (hex). The initiated interrupt must be reset by accessing the interrupt reset register (address: C000:9F8E) in the interrupt service routine.
BIOS and System Programming BEGIN GOTOXY(1,10); WRITE('INTERRUPT 12 was not initiated by PLC END; ') PROCEDURE BASP_INT; BEGIN GOTOXY(1,10); WRITE('INTERRUPT 12 was not initiated by BASP END; PROCEDURE KACHEL_INT; BEGIN MEM[$C000:$9F8E]:=0; ') { Reset interrupt by accessing } { the interrupt reset register } GOTOXY(1,10); WRITE('INTERRUPT 12 was initiated by PLC via bank access END; ') PROCEDURE INT_ANZAHL; BEGIN GOTOXY(1,1); WRITE('Number of initiated INTERRUPTs :',I); END; PROCEDURE INT_AKTIV; BEG
BIOS and System Programming 4.3.6 CMOS-RAM Statusbyte (CMOS-RAM Address 4E) CMOS-RAM used contains additional memory areas from 40 to 4F. These memory areas are used by VIPA for BIOS-extensions and for the VIPA-SETUP, and are protected by a checksum. The user is not allowed to make any changes in this RAM area. Byte 4E - the VIPA-CMOS status byte - is excepted herefrom.
BIOS and System Programming 4.3.7 ROM-SETUP VIPA-BIOS enables an ROM-SETUP. In this case, CMOS-RAM is only used to buffer date and time. The proper system SETUP is filed in the system EPROM. Table for ROM-SETUP is stored in the BIOS-EPROM in the addresses F000:7800 to F000:784E (hex). This table contains as a standard the SETUP table in case of battery failure. Address F000:784F (hex) includes a control flag having following functions: FF For system startup, SETUP from CMOS-RAM is used.
BIOS and System Programming 4.3.8 Bank Interface 4.3.8.1 Operating Modes of Bank Interface The bank interface on the CP486 consists of a 8 KByte RAM memory, which can be written or read from the PLC as well as from the CP side. Memory access and memory size are adjusted via registers on the CP486 side. Following operating modes are available: Operating Banks via Bank Selection Register: In this mode of operation the individual banks are selected via the bank select register on the PLC side.
BIOS and System Programming 4.3.8.2 Bank Interface Registers The registers must be written in the following order: Ident register Bank initial register 1 Bank initial register 2 Configuration register Interrupt reset register (C800:1F80) (C800:1F84) (C800:1F86) (C800:1F82) (C800:1F8E) Ident Register (Address 0C9F80H): By means of this register the bank numbers are set up to which the bank interface on PLC side is responding.
BIOS and System Programming Bank Initial Register 1 / 2 (Address 0C9F84H / 0C9F86H) The start address of the bank on the SPS side is set via the bank start register. The bank start address must be a multiple of the bank size. Moreover it has to be checked, whether the address area is available resp. free at the back plane bus. For the PLC-135 only addresses in the area Fxxx(hex) are possible.
BIOS and System Programming Configuration Register (Address 0C9F82H) The configuration register is used to configure the number of banks, bank size and mode of the bank operation. Programming of this register approves the bank inerface for implementation towards PLC side.
BIOS and System Programming 4.3.8.3 Configuration Example: Standard CP BankOperation (8 Banks with each 1KByte) Configuration: Number of banks: Bank capacity: PLC initial address of the bank: Specified bank numbers: Bank selection in the PLC: 8 1024 Byte F400(hex) (Note: the initial address must be in the Fxxx(hex) range) 8 .. 15 (Note: first number must be a multiple of the number of banks.
BIOS and System Programming 4.3.8.4 Configuration Example: Bank Operation (4 Banks with each 64 Byte) Configuration: Number of banks: Bank capacity: PLC initial address of the bank: Specified bank numbers: Bank selection in the PLC: 4 64 Byte F500(hex) (Note: the initial address must be in the Fxxx(hex) range) 16..19 (Note: the first number must be multiple of the number of banks.

Utility Software for MS-DOS 5. Utility Software for MS-DOS It is recommended to use MS-DOS 4.01 or MS-DOS 5.0 as operating system. Setting up and further description for this operating system is described in the accompanying manuals of Microsoft resp. in supplementary documentation of the publishing house MARKT UND TECHNIK and DATA BECKER. Informations concerning internal system functions can be found in the book PC INTERN of the publishing house DATA BECKER. Concerning the operation systems MS-DOS 3.
Utility Software for MS-DOS 5.1 MS DOS Utilities for Silicon Disk Operation 5.1.1 Silicon Disk Driver The BIOS contains driver functions for operating and usage of standard hardware components. Additional or modified hardware has also to be operated by drivers. For fear that every small system change requires to set up a new BIOS, MS-DOS offers the possibility to couple additional drivers to the BIOS. This happens by means of an entry in the file CONFIG.SYS.
Utility Software for MS-DOS The corresponding driver is installed in the file CONFIG.SYS by the following command: device=[d:][path]SDxxx.SYS [remark][/bb][remark][/llll][remark][/pp] The particular parameters have the following function: [c:][path] drive and path specification with driver SDxxx.SYS, whereby xxx indicates the memory type being used for the silicon disk. The three described drivers SDRAM, SDROM and SDPEROM are available.
Utility Software for MS-DOS Memory Card Silicon Disk with 1MB ROM: DEVICE = \DEVICE\sdrom.sys base address=/80 size=/1024 Explanation: The driver is in the subdirectory "DEVICE" on the boot drive. The silicon disk consists of a read-only memory. Therefore, the driver SDROM.SYS is taken. The base address of the memory card slot is 800000H. The silicon disk has a capacity of 1024 KByte = 1MB.

Utility Software for MS-DOS 5.3 Program CPLINK for Computer Link With this program files can be loaded to the CP486 or read from the CP486 via the serial interface. This way CP486 modules without floppy disk drive or without alternate memory cards can be supplied with data and programs or recorded data can be read out.
Utility Software for MS-DOS 5.4 Program for Visualizing the PLC Process Image The program S5KOP serves in the current version to visualize the process image in the processor of the automation system. The MS-DOS program S5KOP.EXE in the version 1.0 from 4-19-1991 has a capacity of 75645 bytes. VIPA handling modules for the CP486 must be included in the PLC. Calling from MS-DOS is realized via the command "S5KOP". A title screen is displayed which is cleared after pressing an optional key.
Utility Software for MS-DOS 5.5 EMS Driver Driver for the EMS memory on CP486 is contained on the optionally available disk with original QUADTEL software (software package CP4-SW583 (MS-DOS diskette, 3.5", 720KB) included the manual CP4-HB72). This software is only sold as simplex capability, i.e. every system where this driver is utilized requires a licence. This package contains inter alia the following programs and drivers (cf. also section 5.
Linkage with PLC 6. Linkage with PLC 6.1 General Description Data transfer between CP486 and PLC is supported by handling modules on PLC side and by software interrupts on CP side.
Linkage with PLC 6.2 Installation of Bank Software for Linking PLC and CP486 6.2.1 PLC Side: Handling Modules handling modules FB1 and FB2 have to be loaded in the PLC to enable communication with the CP486. Handling module FB1 is called up in OB1 and handling module FB2 in the restart modules (OB21 and OB22).
Linkage with PLC Example for calling up FB2 in OB21: 0000 0005 Module#OB21 BIB ;SPA FB 2 NAME #SYNCHRON SSNR =KY +32 WART =KF +0 PAFE =MB 98 ;BE Transfer parameters: SSNR: KF WART: PAFE: Number of basic bank =0 FB-SYNCHRON does not wait until every single bank is synchronized by CP >< 0 FB-SYNCHRON waits at every single bank until the CP has synchronized this bank BY Scratch markers used: CP 486 ⋅ 00/14 Error acknowledgement message of handling module = 0 no error occurred >< 0 error occurred:
Linkage with PLC 6.2.2 CP486: MS-DOS Driver Program For communication via banks between PC and CP a specific communication driver must be loaded in the CP486. This driver is specific for the communication with the VIPA handling modules. The driver supplies functions which are easy to handle. The user needs no detailed information concerning structure and operation of the banks. The driver contains software to control all banks. At the moment it currently supports: banks 0 and 1 (PC active, CP passive).
Linkage with PLC programs can be started subsequently. This option is only meaningful, if communication ensues exclusively via banks 0 and 1 (CP passive). By pressing the F10-key and subsequent confirmation with "j" the driver will be removed again. /?, /H or /hxx This option shows a list of all possible options of the driver. Attention: The COM-driver is designed to work with CP486-modules of the VIPA GmbH exclusively and can be installed on these systems solely.
Linkage with PLC 6.2.3 Different Data Representation in Memory: For the transfer of data between CP and PC, the different representation of words and doublewords (extended words) on AT and PC (programmable controllers) has to be taken into account. Unlike AT´s the PLC stores the datatype word in a different form in memory, High-Byte and LowByte are stored reverse. In doublewords all 4 bytes are stored in exact reverse order.
Linkage with PLC 6.3 PLC-Jobs for CP486 (Functions for Bank 0 and 1) 6.3.1 Overview All PLC-jobs are transacted via banks 0 and 1. In this way the CPU can use series of MS-DOSfunctions. Die PLC-instructions are processed in background via interrupts, as soon as this driver is being installed. In this way no additional software for the CP486 is necessary to operate the PLC-jobs. The driver permits to call several MS-DOS system functions from the PC.
Linkage with PLC Bank no. 110 Function no.
Linkage with PLC Interface concept for banks 0 and 1 These two banks serve for reading and writing of data from or to the CP486 respectively. If the PLC tries to read data from the CP or write data, it has to call the suitable handling module (SEND or FETCH and RECEIVE). As a result these handling modules provide a job unit in bank 0 or bank 1. A maximum of one job can be entered in the banks 0 und 1 at a time. The size of the data to be transferred ranges from one word up to 504 words.
Linkage with PLC Processing a Read Job: With the handling module FETCH the applications software passes a read job to the CP. This handling module verifies as well as the handling module SEND the specified parameters, creates a job unit in bank 0 and sets the status to 'job is running'. By this the CP detects the existence of a new job and executes this job, as already described under 'Write'.
Linkage with PLC ,6.3.2 Parameterization of Handling Modules: The handling modules SEND (FB3), CONTROL (FB4), FETCH (FB5) and RECEIVE (FB6) are parameterized as follows: 6.3.2.1 Handling Module SEND (FB3, Relative Bank Number: 1): This handling module transfers a data block of up to 504 words from a DB to the CP486. For identification purposes a job number is also sent to the CP486. The handling module supplies the result by means of a display word in a marker word to the application program.

Linkage with PLC 6.3.2.5 Parameterization of File Accesses via Handles The COM-driver allows full access to all drives of the CP and supports access to directories. For every file access a drive and/or directory name can be specified and the same rules are valid, as known from MS-DOS. To access files under MS-DOS numbers, the so called handles are used. The amount of available handles and herewith the maximum number of open files at the same time is specified by the entry FILES = n in the CONFIG.SYS.
Linkage with PLC 6.3.2.6 File Names Like already mentioned, file names can be specified as well with drive and/or path specification. The CP486 software does not affect this. Directories are to be assigned, as usual, with a backslash (ASCII-Code 92, 5C hex). The character can also be entered correctly with the PG. The maximum length of a path specification is up to 64 characters.

Linkage with PLC 6.4 CP486 Jobs for PLC (Functions for Bank 2, 3 and 7) 6.4.1 Overview The driver program CP386COM serves jobs initiated by the PLC, as well as jobs initiated by the CP386. The driver supplies a series of functions for the banks 2, 3 and 7. With these functions data can be read from the PC or written to the PC respectively from a running application on the CP486. All functions are called by means of software interrupt 78h.
Linkage with PLC 6.4.2 Driver Functions via Software Interrupt 6.4.2.1 CP-Status Call This function outputs various arbitrary status information via the CP486. Moreover, it can be used by the applications software to check whether the CP486 software driver is loaded. Further information returned is the output status of hard and software, CPU identification etc.
Linkage with PLC 6.4.2.2 Read a Single Element from the PC With this function a single data type (bit, byte, word,...) can be read from the PC. The function is just starting the job and does not wait for the PC to execute it, but returns immediately, to where it was called. Therefore the data can be read not before the function 'status call' was executed (see there).
Linkage with PLC 6.4.2.3 Read a Block from the PC With this function a whole block of data can be read from the PC. The function is just starting the job, and does not wait until the PC is executing it, but returns immediately to where it was called. Therefore the data can be read not before the function 'status call' was executed (see there).
Linkage with PLC 6.4.2.4 Write a Variable to the PC This function enables to write single data (bit, byte, word,...) to the memory of the PC. When calling, the address of a variable to be written must be specified. The function transmits its value to the bank and does not wait for the PC to read the data, but returns immediately to where it was called.
Linkage with PLC 6.4.2.5 Write a Block to the PC With this functions a whole data block can be transmitted to the PC. When calling, a pointer to the data block is to be specified. The function writes the data to the bank and returns immediately to where it was called. There is no delay for the PC to read the data. Subsequently the data block is competely available in the CP and could be overwritten for example.
Linkage with PLC 6.4.2.6 Read Job Status With this function, the status of an earlier started job can be called. For read jobs, variable and block read jobs, this function copies data to a specified address to the CP, if the job status is 'finished without error'.
Linkage with PLC - For a read job for single variables, the pointer is to be interpreted differently, depending on the element size: Bit or semaphore: The pointer is the address of a byte, the bit will be written to bit number 0, the whole byte will be overwritten. Byte, left byte, right byte: The pointer is the address of a byte. The byte will be written to the storage cell. Word: The pointer is the address of a word. High and low-byte will be interchanged during transmission.
Linkage with PLC 6.4.2.7 Abort All Jobs of a Bank Register high AX In low Out fn fn function number for status call $28 abort all read jobs $38 abort all write jobs status <0 0 status error number because error occurred all jobs were aborted. All not yet finished write or read jobs can be aborted by means of this function. It must not be differed between variable and block jobs. Also if there were no jobs active in the bank, the function answers with the return value 0.
Linkage with PLC 6.4.2.8 Read Status of Process Image Register high AX status In $70 0 1..255 low Out - status no process image available current process image counter The current value of the process image counter (bank 7 address 3FEh) can be read by means of this function. If the value is 0 then no process image is available.
