CHAPTER 4 OPERATION 4-1 4. OPERATION 4.1. Initial reset. The series DT105/110/203/X displays are industrial displays controlled by serial line RS-232 or RS-485, from 1 to 8 rows and 1 or 2 display sides. Before connecting the display to the power supply, it must be checked that all connections have been set properly and that the display has been firmly fixed.
4-2 OPERATION CHAPTER 4 4.3.1. Modify parameters To go into modify parameters menu, you should push the advance pushbutton for more than three seconds, labelled with «*». After the 3 seconds, the display shows the first parameter in flashing mode. From this point, there are two options: 1- Display the parameters value. By pushing advance (“*”) you may see the parameters value. The increase pushbutton, labelled «+», lets you modify the parameter.
CHAPTER 4 OPERATION 4.3.3.7. Parameter 7: Stop Bits Selects the transmission number of stop bits. Select 1 or 2. 4.3.3.8. Parameter 8: Serial input Selects the transmission type of serial line: RS-232 or RS-485/RS-422. 4.3.3.9. Parameter 9: Test serial L. Selects the transmission test of serial line. There are three levels : 0 = No test 1 = Test transmission errors 2 = Test transmission errors and display address error. 4.3.3.10. Parameter 10: Date Allows you to modify the display date. 4.3.3.11.
4-4 OPERATION CHAPTER 4 4.4. Protocols. Protocols are the procedures used by displays to communicate with other equipment. Each protocol has its own specifications explained in detail in the following paragraphs. Definitions of words used in protocol descriptions: Message: Alphanumerical text of one or more lines (according to display model). For each message, a line must be static or dynamic. In static message, line text is equal to or shorter than the number of characters of on a line.
CHAPTER 4 OPERATION 4-5 4.4.1. TDL protocol. The TDL protocol must be selected to save new messages into the memory. After power on, the display always shows all messages stored in the memory in Continuous mode. The Continuous mode is reset when the serial line sends a message to display. In Message mode, the display only shows the last message received. To return to continuous mode, see 4.4.1.8.4 “Set CONTINUOUS mode”.
4-6 OPERATION CHAPTER 4 4.4.1.3. Number of bytes. 1 byte. Is the number of bytes which forms the block of information. It begins to count from the byte of the address number to the second byte of CRC, both included. The value of the number of bytes must be, in hexadecimal type, between 6h and 250h. 4.4.1.4. Data. The Data consists of the message texts, the control characters and the error codes.
CHAPTER 4 OPERATION 4-7 The date and time can be displayed in any place in the text. Date and time take characters of variables, and so it consequently, it must be taken into account that in a message, the amount of characters reserved for variables can just take 16 characters. Example: Text of display =”PQRSTUV” Transmission block: 00h 02h 00h 10h 00h 1Bh 06h 50h 51h 52h 53h 54h 55h 56h 00h 0Dh 51h 06h 00h 03h 00h 02h Start 00h Display num. 0 10h Number of bytes in hexadecimal.
4-8 OPERATION CHAPTER 4 ONLY WITH HUMIDITY AND TEMPERATURE OPTION “00h 1Eh” displaying temperature in Celsius. It needs 6 characters. “00h 1Fh” displaying temperature in Farenhait. It needs 6 characters. “00h 21h” displaying relative humidity. It needs 2 characters. The date and time can be displayed from any place in the Text. It takes characters of variables. The amount of characters reserved for variables can just take 16 characters per line. Example: DISPLAY Num.
CHAPTER 4 OPERATION 4-9 4.4.1.8.3. Updating Date and Hour of Clock Calendar. The Clock Calendar can be updated by external push buttons or via software. To modify the date and time it is necessary to send the data, in ASCII, except for the control byte , with the following structure. Set time and date Day Month Year Blank space Hour Minutes 00h 1Ch DD MM AA HH MM The seconds are reset when the time is updated. Example: DISPLAY Num.
4-10 OPERATION CHAPTER 4 Example. DISPLAY Num. = ALL displays Transmission block: 00h 02h 00h 08h 00h 1Dh 00h 0Dh 00h 18h 00h 03h 00h 02h 00h 08h 00h 1Dh 00h 0Dh 00h 18h 00h 03h Header. Display numumber 0. All displays Number of bytes in hexadecimal. (16 decimal) Reset presentation mode. End of data. CRC End of block 4.4.1.9. Display response. After receiving a transmission block , the display returns a response block of conformity or error.
CHAPTER 4 OPERATION 4-11 Transmission block Address 10h Control First Words High Words Low Bytes Data CRC Low CRC High Address: The display address 10h: ModBus code. Always 10 in hexadecimal. Control: Control mode and line number. First: Position of first character sent. Words high and Words low: Number of words sent into data. Bytes: Number of bytes sent into data. Data: Data sent to display. CRC low and CRC high: CRC value.
4-12 OPERATION CHAPTER 4 4.4.2.4. First. 1 Byte. Direct control: The position of the first character is sent to the display. Position 1 is the one placed on the left side of the display. The character placed on the left of the first character should not be modified. Position =1: Only the new text which has been sent is displayed. Position >1: The current text is modified and it begins with the position sent.
CHAPTER 4 OPERATION 4-13 4.4.2.8. CRC. 2 Bytes. It is the result from CRC according to J-BUS/MODBUS protocol.The CRC is made of all characters except the resulting CRC using the following process. 1. Assign the value FFFFh to CRC register. 2. Make an exclusive OR between the CRC register and the first byte, store the result in CRC register. 3. Right rotation of CRC register. Copy LSB to carry bit and set MSB to 0. 4.
4-14 OPERATION CHAPTER 4 0Ah or 0Ch characters forces a change of line on multinear displays. It allows all the lines from a single dislay to be sent in just one data block. Example: Display of 8 lines. Address 2 Sent code: 02h 10h 04h 01h 00h 04h 08h 31h 32h 33h 34h 0Ah 41h 42h 43h CRC Modify line 4 to: 1234, modify line 5 to: ABC. The rest of lines are not modified. Code 00h is transparent and therefore any character will not be displayed 00h 22h Brightness adjust.
CHAPTER 4 OPERATION 4-15 Message with variables. The message number is the two first bytes of the data block. See Message without variables. The position and values of variables follow the message number with this format: Pv Nc Dv Pv: Position of variable. Nc: Format and character number. Dv: Variable data. Pv: Position of variable. 1Byte. Every line can display up to 16 variable characters. A display of eight lines can display up to 128 variable characters.
4-16 OPERATION Bits D7-D5 = 011 CHAPTER 4 Variable in 2 byte hexadecimal. Displayed in hexadecimal. Needs 4 variable characters when the message is edited Example: Variable sent: 8765h. Value displayed: 8765 Bits D7-D5 =100 Variable in 2 byte hexadecimal. Displayed in decimal. Needs 5 variable characters when the message is edited Example: Variable sent: 8765h. Value displayed: 34661 In Bits D4-D0 must be the number of characters sent. Dv: Variable data.
CHAPTER 4 OPERATION 4-17 4.4.3. Omron protocol. Omron protocol supports two kinds of messages. Messages with and without variables.With this protocol the display may control as many as 6 messages without variables and 4 messages with variables together. All messages are shown sequentially. To know what message should be shown, the display reads a table of 18 DM’s from the PLC memory. The first DM number must be configured into the DM parameter. This parameter is specific for this protocol.
4-18 OPERATION CHAPTER 4 4.4.3.3. Set a message with variables. When you want to set a message with variables, you should put the Message Number into a free place on the DM table, between positions DM n+6 and DM n+9. If more than one message is set, the position into the table is used to control the order in which messages will be displayed. Using Messages with variables, besides the message number, you must program the position where the variable will be found inside the PLC.
CHAPTER 4 OPERATION Line 1 2 3 4 5 6 7 8 Position in decimal 1-16 17-32 33-48 49-64 65-80 81-96 97-112 113-128 4-19 Position in hexadecimal 1h-10h 11h-20h 21h-30h 31h-40h 41h-50h 51h-60h 61h-70h 71h-80h A variable position is independent of used variables, this means that although no variable is used in line 2, the first variable in line 3 is in position 33. The variable position must be in hexadecimal code.
4-20 OPERATION CHAPTER 4 4.4.4. ASCII protocol. The ASCII protocol is an easy protocol to connect between the display an any kind of equipment with a serial line, like a PC. This protocol also allows displays to be connected in a network by means of an RS-485 interface. In this protocol, the display works a slave. It waits to receive a transmission block and if it is correct, acknowledges the block and displays data.

S7-200 protocol.
4-22 OPERATION CHAPTER 4 4.4.5.1. Set a message without variables. When you want to set a message without variables, you should put the Message Number into a free place on the VM table, between positions VM n and VM n+5. If more than one message is set, the position into the table is used to control the order in which messages will be displayed. 4.4.5.2. Reset a message without variables.
CHAPTER 4 OPERATION 4-23 4.4.5.4. Reset a message with variables. To reset a message with variables, you must set its position on the table to 0 or change the message number for another message number. 4.4.5.5. Reset all messages . To reset all messages, you must set all positions from VW n to VW n+9 to 0. 4.4.5.6. Data variables. The data variables must be placed into groups of consecutive VM’s for each message.
4-24 OPERATION CHAPTER 4 4.4.5.7. Examples S7-200 MPORTANT: To store the messages in the display you should use TDL software. See 4.2 “Message programming”. Example of message without variables. Messages 12 and 53 must be stored in the display. Use these texts as examples.: Message 12: OIL PUMP Message 53: TANK 2 FULL The PLC program will be as follows. // //EXAMPLE PROGRAM FOR MESSAGES WITHOUT VARIABLES // // The display parameter VW must be equal to 1000. // Input I0.0 ON, sets message 12.
CHAPTER 4 OPERATION Message with variable example. The values of two counters are displayed in a message. The PLC program will be as follows. // The display parameter VW must be equal to 1000. // Message 25 is used. //The text message is: LONG=[V][V][V][V] SHORT=[V][V][V] // Input I0.0 ON resets the message 25 // Input I0.1 ON sets the message 25 // Input I0.2 ON increments LONG counter // Input I0.3 ON increments SHORT counter // Input I0.4 ON resets both counters.
