2.8 Communications with an OMRON PLC (FINS Communications Service)
Using the MSG-RCVE Function with the MP3000 as a Slave
2-196
Transfer Size
The following table lists the data sizes that can be received in a single FINS command when using the
MSG-RCVE function. When executing SEND, RECV, and CMND instructions on an OMRON PLC that
is acting as the master, keep the data size within the ranges that are given in the following table.
Setting Example
The following figure illustrates how the contents of the MW10000 to MW10099 hold registers in the
MP3000 slave are read into D10000 to D10099 in the DM Area in the CPU Unit of the OMRON PLC
master.
