z Application Example
I/O data is used as described in the following table when using Position Control Units and High-
speed Counter Units and Synchronous Units.
* Synchronous Group Stop Command Bits and Synchronous Unit Stop Command Bit
Command bits can be used from the CPU Unit to stop the function that is currently being executed for Synchro-
nous Units that are performing synchronous unit operation. There are two command bits. The Synchronous Unit
Stop Command Bit applies to all Synchronous Units. The Synchronous Group Stop Command Bits apply to pre-
set groups of Synchronous Units.
