15.3 GPRECV (General-Purpose Communication Receive Instruction)
● Depending on the communication format of an external device, if a header and a terminator
are contained, they are stored in the operation memory as part of receive data. When
necessary, insert a program to extract data content.
● In the case of a direct address and an index modification address, specify the same device
for D1 and D2. At the same time, specify the addresses so that D1 is less than D2.
● As the communication cassette (Ethernet type) has an Ethernet-serial conversion function, the
internal interface operates with similar programs as the case of SCU. The setting method and
programming method are different from those for the CPU with built-in ET-LAN. Refer to the
section describing the case of SCU.
