CQM1 Application
Example
When a macro is used, the program can be simplified as shown below.
CPM1/CPM1A/SRM1
Application Example
The CPM1/CPM1A/SRM1 program can be simplified like the one shown
above, but words SR 232 through SR 235 would be used instead of IR 096
through IR 099 and words SR 236 through SR 239 would be used instead of
IR 196 through IR 199.
2-4 Differential Monitor
The CQM1/CPM1/CPM1A/SRM1 support differential monitoring from either
the Programming Console or the SSS. The operator can detect on OFF-to-ON
or ON-to-OFF transition in a specified bit. When the specified transition takes
place, the transition is indicated on the display and a buzzer sounds to enable
easy recognition of the transition.
Refer to the CQM1 Operation Manual, CPM1 Operation Manual, CPM1A
Operation Manual or SRM1 Master Control Units Operation Manual for details
on the Programming Console Differential Monitor procedure and to the SSS
Operation Manual: C-series PCs for the SYSMAC Support Software proce-
dure.
