D.1 Message Send Function (MSG-SND)
( 4 ) Connection Number (PARAM02)
Refer to D.1.4 ( 4 ) Connection Number (PARAM02).
( 5 ) Option (PARAM03)
Choose a unique setting for each communication device.
The following table provides the scope of the setting.
Communication Device
Ethernet(218IF, 218IFA or 218IFC) 0 to 247, 255
( 6 ) Function Code (PARAM04)
Set a function code to transmit.
The functions (read coil and input relay state, write to holding register, etc.) registered in the function codes are made
available by specifying the code.
The following table shows the available function codes when using MODBUS/TCP as a protocol.
