Chapter 6 Applied Instructions ASCII mode: You do not need to convert the ASCII codes, and they are expressed in 16# values. ES3 sends the communication command: “01 03 10 20 00 08 C4 CR LF” ES3 receives the communication command: “01 03 10 12 34 56 78 11 22 33 44 55 66 77 88 99 AA BB CC AA CR LF” RTU mode ES3 sends the communication command: “01 03 10 20 00 08 41 06” ES3 receives the communication command: “01 03 10 12 34 56 78 11 22 33 44 55 66 77 88 99 AA BB CC 90 FE” M0 is ON when there is no error in the data. After the receiving of the data sent from the DVP-ES2, the PLC confirms the data format sent from DVP-ES2.
If there is no error in the format, M0 is ON; otherwise, M1 is ON. M2 is ON if there is no response. The corresponding special flags SM100, SM102 and SM104 are ON as well. 3. The following table lists the content values in D10–D17 of ES3 CPU. 6_ Additional remarks 1. If you declare the operand in IPSSoft, the data type is ARRAY [3] of BOOL. 2. If D +2 exceeds the device range, the instruction is not executed, SM0 is ON and the error code in SR0is 16#2003. 6-591 Device D10 D11 D12 D13 D14 D15 D16 D17 Value (16#) 1234 5678 1122 3344 5566 7788 99AA BBCC
