1.4.4 V79 PDI-1 AND V80 PDI-2 COMMANDS AND DATA PRESENTATION The PDI-1 and PDI-2 have sixteen input channels capable of sensing, recording, and reporting information from dry contact closures (PDI-1) or optically isolated inputs (PDI-2). A module can observe, record, and report when an event happened, how long the event lasted, and how many events occurred. An event is defined as a change-in-state of an input from LO to HI (or vice versa) and return to the original state.
is selected, a message is reported at the start of an event. If Schedule Reporting Method is selected, events are buffered and reported at specific user-selected times or intervals.
The following example shows messages received using immediate or schedule reporting where the PDI-1 or PDI-2 is installed in Unit 1 Module 15 with Time Tagging enabled: 1:15,1 1 11/18/97 09:12:22 1:15,2 1 11/18/97 09:12:22 where 1:15,1 represents Unit 1/Module 15/Channel 1, 1:15,2 represents Unit 1/Module 15/Channel 2, 1 indicates that Channel #1 and Channel #2 are closed, 11/18/97 09:12:22 is the time tag which is the same for both channels in this example, and is the Carriage Retu
If you issue the RS1 command (Report Single Buffered Event), the module responds with a message showing the input status for Channel 1 similar to the following: 1:15,1 1 11/18/97 09:12:22 where 1:15,1 represents Unit 1/Module 15/Channel 1, 1 indicates the first buffered sample for Channel 1 is closed, and 11/18/97 09:12:22 is the time tag. The table below summarizes the commands supported by the PDI-1 and PDI-2.
1.4.5 V74 EIA-232 SERIAL MODULE OPERATION The V74 4-port EIA-232 serial module will simultaneously multiplex incoming data from connected peripheral devices (e.g., bar code readers, digital laboratory instruments, etc.). The V74 allows the host computer to individually select any peripheral device and send data to the selected device. The V74 has four modes of operation. Full duplex reporting mode provides full duplex communication between the host computer and a selected peripheral device.
Command reporting mode allows the host computer to send commands requesting messages or any buffered data from the V74 ports. These commands are summarized in the table on the following page. See Section 1.4.1 for the procedure to send commands. As an example, suppose the V74 is installed in Unit 1 Module 15 and is using Command Reporting Method.
reports all messages in the buffer at the time the command was sent. If there are no messages, is sent to the host controller. RBn (n=1 to 4, 0=all) Report All Buffered Data. This command reports all data in the buffer at the time which the command was received with no regard for messages. If there is no data, is sent to the host controller. RSn (n=1 to 4, 0=all) Report Single Message. This command reports a single buffered message.
The I/O modules are used to interface directly to various peripheral devices such as security/alarm systems, process control systems, medical data systems, and environmental control systems. The I/O module types include a 16 or 8 channel 12 bit A/D converter, 8 channel control relay, 16 channel switch or optically isolated inputs, 4 EIA-232/422 serial I/O ports, and 4 EIA485/422 serial I/O ports.

15.1.1 V50/V73/V74/V75/V76/V86/V87 SERIAL PORT CONFIGURATION The V50/V73/V74/V75/V76/V86/V87 module translates data for devices using different serial configurations. You can set the baud rate, word size, stop bits, parity and XON/XOFF handshaking for each port. Factory default configuration on serial ports is 9600 baud rate, 8 bit word size, 1 stop bit, no parity and XON/XOFF disabled. 15.1.
PORT ID The Port ID feature allows a user to enable or disable the Port ID for individual I/O ports. When Port ID is enabled, a port identification code proceeds data sent to the host computer when using Immediate and Command Reporting modes. The Port ID can consist of the Unit Number:Module Number,Port Number corresponding to the I/O port that received the data. The Port ID can also consist of the Device Name assigned to the I/O port in the configuration mode.
modes of operation. Section 15.2 provides more detail for operating in the various modes. The default mode of operation is full duplex mode. 15.1.6.1 FULL DUPLEX MODE Full duplex mode increases input/output by interfacing the host module to four peripheral devices for each module. The host system selects a specific port by sending a port select sequence. The host system remains connected to the selected port until another port is selected.
15.1.6.2 IMMEDIATE MESSAGE MODE Immediate message mode provides multiplexing of all messages from all ports to the designated host module automatically. Data is buffered until an end of message terminating character is received or 256 bytes are received. The messages are sent to the host device and can be preceded by a port identification code corresponding to the unit, module, and port number or the device name of the peripheral port that sent the message. 15.1.6.
designated host device in a round-robin fashion. 15.1.7 V50/V73/V74/V75/V76/V86/V87 TIME TAG The module can be programmed to provide a time tag in immediate or command operation mode. A time tag provides the month, day, year, hour, minute, and second the message or block of data was recorded according to the M Series main unit's time-of-day clock. The time tag is inserted after the port identification code if enabled.
15.2 V50/V73/V74/V75/V76/V86/87 OPERATING IN THE DIFFERENT MODES A typical application using a V50/V73/V74/V75/V76/V86/V87 module would have a host computer such as an IBM PC connected to the host module and various devices such as cash registers, digital laboratory instruments, bar code readers, numerical machines, printers, modems, terminals, etc. connected to the serial ports.
received or 2048 characters have been received without a terminating character. Immediate data mode is similar to immediate message mode as discussed in Section 15.2.3. The primary difference is that immediate data mode does not wait for a message terminating character to send data to the designated host module. Data is sent to the designated host module automatically as soon as it is received by any port on the peripheral communications module.
module in order to issue the clear buffer command. This is done by sending the port select code, the appropriate Unit Number followed by a colon (1: to 30: - only if using cascaded units), the module number (2 to 16), and Carriage Return or Line Feed. You can issue the clear buffer command for multiple ports by separating the port numbers with a comma. For example, to clear the receive buffer for Ports 1 through 3 of the selected module, send CB1,2,3.
15.2.1 OPERATING IN FULL DUPLEX MODE In full duplex mode, the V50/V73/V74/V75/V76/V86/V87 module provides full duplex communication between the host module and the selected port. The host module and the selected port remains connected until a different port is selected or until the host module disconnects from the module by sending the port select code followed by Carriage Return.
followed by a message from Module 2 Port 2 followed by a message from Module 3 Port 2, and so on. NOTE: The designated host computer can select and transmit data to any serial port while simultaneously receiving messages from all ports. A terminal connected to a non-designated host module can select and send data to any port. However, messages are sent to the designated host terminal only. If a connection exists between a host module and the desired port, the requesting host module is sent a busy message.
The V71 host module remains in full duplex communication with Module 2, Port 1, until a disconnect is sent ($BT) or a different port is selected. When a disconnect command is sent, the peripheral module reverts back to the previous mode of operation. 15.2.3 OPERATING IN IMMEDIATE DATA MODE Immediate data mode is similar to immediate mode as described in Section 15.2.2 above.
15.2.4 OPERATING IN COMMAND MODE Command mode provides multiplexing to a host module of messages or buffered data from individual ports or all ports upon request from the host computer via data commands. The host computer can request single messages, all messages, or all current buffered data for individual ports. V50/V73/V74/V75/V76/V86/V87 data commands are sent through a host module using the following procedure: 1.
and 5 Section 15.2.3.1 through Section 15.2.3.6 provide detailed information on the functionality of each supported data command. Appendix A provides these same commands in a condensed version for quick reference. 15.2.4.1 CLEAR BUFFER (CB) COMMAND The Clear Buffer (CB) command deletes all present messages or data in the buffer for the specified port(s) in any of the reporting modes. This command has the following format: CBn where n is the desired port number (1 to 4 or 0 for all). 15.2.4.
15.2.4.3 REPORT ALL BUFFERED DATA (RB) COMMAND The Report All Buffered Data (RB) command instructs the module to send all data currently stored in the buffer for the specified port(s) whether or not it is a "message" as defined on page 87. Data from the lowest numbered port specified is sent first. This command has the following format: RBn where n is the desired port number (1 to 4 or 0 for all).
command has the following format: SRn where n is the desired port number (1 to 4 or 0 for all). 15.2.4.6 PORT ID STATUS (ID) COMMAND The Port ID Status (ID) command instructs the V50/V73/V74/V75/V76/V86/V87 to report its current Port ID status for the selected module. This command has the following format: ID. When a user sends the ID command, a status message similar to the following is sent: Unit 01, Module 02 Port I.
send the command $BTB2,3,4 to the V71 host module where is Carriage Return. The 4-port serial module remains in broadcast mode until the V71 host module issues a disconnect command consisting of the port select code followed by Carriage Return (e.g., $BT). If a peripheral communications module is configured to operate in immediate reporting mode (see Section 15.2.
