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 SEND instruction is executed, the data is read from the device that starts from [S]
in the master unit and the data is stored in the address that starts from [D1] (upper address)
+ [D2] of the partner unit.
● The transfer method (register transfer/bit transfer) varies according to the device types that
are specified by [S] and [D1].
● The execution result code is stored in the one-word area of the master unit that is specified
by [D3].
■
Specification of [S], [n], [D1], and [D2]
● The transfer method and the amount of sent data [n] vary according to the type of the device
on FP7 that is specified by the operand [S].
