Chapter 1 Summary
1-11
Upper PLC Link System (CCM Master Function)
Purpose
Transfer and collection of production control information to slave PLC by master PLC, and maintenance and
management of slave PLC by master PLC
Feature
Writing from master PLC to slave PLC and reading from slave PLC to master PLC
Target memory
The timing and error status of communication, such as function memory, program memory, and CPU
operation mode, are defined in special relay (SP).
Method
Make the master PLC program execute communication commands (RX, WX).
(2)
Upper Link System with RS-485 Repeater
The RS-485 repeater can be used to connect up to 90 stations. For details, refer to the CCM slave function in (1) and the
CCM master function in (2).
Examples of connections (using PORT2) are shown below.
(3)
PLC link system (peer-to-peer function)
Purpose
Two CPUs are of the same grade on the system and are used when a call is required from both parties.
Feature
Both become masters when necessary and make calls, in which case one PLC is a slave. If a call is made at the
same time, the PLC with the lowest station number takes precedence.
Method
Make the caller execute the communication command (WX, RX) in the PLC of the caller.
