Serial Communications
Section 6-3
Message Communications Functions
The FINS commands listed in the table above can also be transmitted through
the network from other PLCs to the CPU Unit. Observe the following points
when transmitting FINS commands through the network.
• CPU Bus Units (such as Controller Link Units or Ethernet Units) must be
mounted in the local PLC and destination PLC to transmit FINS com-
mands.
• FINS commands are issued with CMND(490) from the CPU Unit’s pro-
gram.
• FINS commands can be transmitted over three networks at most. The
networks can be the same type or different types.
Refer to the CPU Bus Unit’s Operation Manual for more details on the mes-
sage communications functions.
