Outline of operation
● This instruction sends commands from the communication port of the unit to send/receive
data to/from devices that support "MC protocol".
● 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 from
[S1] (upper address) + [S2] in the partner unit and the data is stored in the area that starts
from [D1] in the master unit.
● The transfer method (register transfer/bit transfer) varies according to the device types that
are specified by [S1], [S2], and [D1].
● The execution result code is stored in the one-word area of the master unit that is specified
by [D2].
■
Precautions for programming
● Use the UNITSEL instruction immediately before the SEND/RECV instruction to specify a
target connection number for communication.
