Voltage/ Unit . Data format=00
Note: Some Modbus utility support 2 byte data each channel like Modbus Poll , but the
TRP-C68 standard mode is support 5 byte for display , If user use the that utility ,the
TRP-C68 must be adjust the data format .
Example :
Send command: “02 46 06 00
06
00
08
00
02
00 00”….Set the BD=06=9600, TT=08=+/-10V,
DF=02=Engineer display.
Response: “02 46 06 00 00 00 00 00 00 00 00”……Command valid.
Then send the command : “1 3 0 0 0 1”……Read channel 0 voltage
Response:”

Note: The engineer’s display is 0000(hex)~8000(hex)~FFFF(hex)=-10V~0V~+10V
