The italicised Pr
91.22 is a status parameter and does not require setting. It shows
whether the module has achieved the Inter-Option functionality specified in Pr
91.21.
For more information refer to Pr
91.12.
Before setting the parameters above, the POS tasks may be executing out of phase
with each other as shown in Figure 10-3 POS Task Execution BEFORE Inter-option
Synchronization with CTSync . After setting the parameters to the values shown above
the POS tasks should be executing in phase with each other as shown in Figure 10-
4 POS Task Execution AFTER Inter-option Synchronization with CTSync .
When a module is a CTSync Slave, it has to be the Inter-Option Synchronization
Producer on the drive it is fitted to therefore Pr
91.21 will automatically be set to a value
of 1.
