Outline of operation
● Commands are sent from the communication port of the unit to perform the data
transmission with external devices. Message in accordance with the protocol is automatically
formulated by PLC. The user program only has to specify the station number and the
memory address, and execute the SEND/RECV instruction, to carry out reading and writing.
● Select a communication mode in the configuration menu of the tool software FPWIN GR7.
● When the SEND instruction is executed, data are read from the device in the master unit,
starting with [S], and stored in the address starting with [D2] of the partner unit.
● The transfer method (register transfer/bit transfer) varies according to the device types that
are specified by [S] and [D2].
● The amount of sent data [n] is specified in words for the register transfer, and in the number
of bits for the bit transfer.
