Outline of operation
● This instruction reads data that is sent from an external device and received by the
communication port of the unit.
● This instruction reads received data from the communication unit and the communication
port set by the UNITSEL instruction, and stores the number of received bytes in the area
specified by [D1] and the received data in the areas [D1+1] to [D2].
● In the case of SCU, data received from the partner are stored in 8 receive buffers for each
COM port. By executing the GPRECV instruction, data in the receive buffer can be copied to
a given operation memory.
● In the case of CPU with built-in ET-LAN, data received from the partner are stored in 1
receive buffer for each connection. By executing the GPRECV instruction, data in the receive
buffer can be copied to a given operation memory.
