07 : type code (07 means the M status)
01 : length field = number of bytes of M(Function block status(1/0))
04: status of the M (M1=0,M2=10,M3=1,M4=0)
0d 08 00 00 00 00 00 00 01 c2
0d : type code (0d means the AM value)
08 : length field = number of bytes of AM
00 00 00 00 00 00 01 c2: AM value (AM1=00 00,AM2=00 00,AM3=00 00,AM4=01 c2)
The server end need do response like this:
00 00 00 00 00 02 01 8b
You can use the above fixed data as the response for the customize MODBUS.
So if the "Trg" input keeps high, the the output will be high also after the EXM get the above correct response.
Note:The command format is based on the standard Modbus TCP. Please refer to the technical file "Modbus
TCP communication protocol" for detail if require.
6.3 Basic functions list – GF
Basic functions represent simple logical elements of Boolean algebra.
You can invert the inputs of individual basic functions , i.e. the circuit program inverts a logical “1” at a
relevant input to a logical “0”; if “0” is set at the input, the program sets a logical “1”.
The GF list contains the basic function blocks you can use for your circuit program. The following basic functions
are available:
