DVP-ES3 Series Programming Manual ASCII mode You do not need to convert the ASCII codes, and they are all expressed in 16# values. ES3 sends the communication command: “ ： 01 10 0600 00 08 10 1234 5678 1122 3344 5566 7788 99AA BBCC 8F CR LF” ES3 receives the communication command: “ ： 01 10 06 00 00 08 E1 CR LF” RTU mode ES3 sends the communication command: “01 10 06 00 00 08 10 1234 5678 1122 3344 5566 7788 99AA BBCC 0B 0C” ES3 receives the communication command: “01 10 06 00 00 08 C1 47” If the format is correct, SM100 is ON. 5. After receiving the data sent back from the DVP-ES2, the PLC confirms the data format sent back from the DVP-ES2, and determines if it is correct.
If no error occurs in the format, the corresponding special flags SM100 are ON; if not SM102 is ON. When the DVP-ES2 receives this instruction, it writes data stored in the devices D20–27 to the device T0–7 in the DVP-ES2. _6 6. Since this function code writes data, the operand n is ignored. Additional remarks 1. If the value in S 1 or S 2 exceeds the range, an operation error occurs, the instruction is not executed, SM0 is ON, and the error code in SR0 is 16#2003. 2. If the device specified by S is not sufficient to contain the n pieces of data, the instruction is not executed, SM0 is ON, and the error code in SR0 is 16#2003. 3.
If n exceeds the range, an operation error occurs, the instruction is not executed, SM0 is ON, and the error code in SR0 is 16#200B. 4. If the function code specified by S 2 is related to bit devices, the device specified by S must be a bit device; otherwise, an operation error occurs, the instruction is not executed, and the error code in SR0 is 16#2003. 5. If the function code specified by S 2 is related to word devices, the device specified by S must be a word device; otherwise, an operation error occurs, the instruction is not executed, and the error code in SR0 is 16#2003. 6. If the communication command is 0x05 or 0x06, the value in n can be ignored.
The length of the data is only one bit 6-546 Device T0 T1 T2 T3 T4 T5 T6 T7 Value (16#) 1234 5678 1122 3344 5566 7788 99AA BBCC
