The PLC will use MODBUS RTU protocol, via its Comm port
#3, to write 8 words of data from DM[11] to DM[17] to the slave MODBUS device with ID = 05
and into it's register offset address 101 to 108 (in MODBUS term this refer to the #40102
to #40109 holding register) . The command automatically checks the response
string received from the slave device for the correct slave address CRC16. Like READMODBUS
command, the status of this operation can be checked by the user program by testing the
STATUS(2) function. |
