Outline of operation
● Commands are sent from the communication port of the unit to perform the data
transmission with external devices.
● Data can be read and written by specifying station numbers and memory addresses and
executing the SEND and RECV instructions in a user program, because PLC automatically
creates messages according to the protocol.
● Select a communication mode in the configuration menu of the tool software FPWIN
GR7.
● When the RECV instruction is executed, the data is read from the address that starts with
[S2] in the partner station number [S1] and the data is stored in the area that starts with [D1]
in the master unit.
● Depending on the type of device specified by [S2] and [D1], the transfer method (register
transfer / bit transfer) varies.
