Controller's mode of operation:
RUN: Controller is running normally.
Note: (For C30S, C50S, C70S and C75S Controllers only)
Blinking RUN text on master slide on lower right hand corner indicates
controller is in invalid mode, which means there are some forced output(s)
present in Safety portion of the controller configuration and user changed the
controller mode to RUN-LOCKED mode from RUN-PRGM mode.
PROG: Controller is in Program mode.
OFLN: Controller is in Offline mode.
FAULT: A fault was found reading the Controller switch.
NO COMM: This is displayed if controller is not responding.
Line frequency. Used for configuring the conversion time of the A/D converter.
The analog control cycle time in seconds. This value is determined from the
execution time estimated from the configured control scheme. Cycle Time and
Fast Cycle Time increase (slow down) as the following increase: CPU % Used,
Fast CPU % Used, Dynamic Memory, Config Memory. Also, extensive use of
Free Form Logic blocks (as opposed to equivalent gate logic) can substantially
increase Fast Cycle Time.
Calculation of percentage of time the CPU is active during the analog cycle time
Maximum time used to complete the analog cycle
Number of times that the processing of the analog control blocks exceeds the
allocated analog cycle time
Cycle Time and Fast Cycle Time increase (slow down) as the following
