Instruction Description
GSV Identifies whether to use the RPI specified by the producer.
Value Meaning
0 Do not use the RPI specified by the producer
1 Use the RPI specified by the producer
GSV Number of controller log entries that originated from a program/task properties change, an online
edit, or a controller timeslice change. It can also be configured to include log entries originating
SSV
from forces. The number will be reset if RAM enters a bad state. The number is not capped at the
largest DINT, and a rollover can occur.
GSV Number of controller log entries since the last firmware upgrade. The number will be reset if RAM
enters a bad state. The number is capped at the largest DINT.
SSV
GSV Percentage (0...100) of free data table memory set aside.
GSV Used to configure the suppression of selected faults encountered when an SFC action is
postscanned. Only valid when SFCs are configured for automatic reset.
SSV
Value Meaning
0 Do not suppress faults during postscan execution
(default behavior - recommended).
1 Major faults 4/20 (Array subscript too large) and 4/83 (Value out of range)
are automatically suppressed while postscanning SFC actions.
When a fault is suppressed, the controller uses an internal fault handler to automatically clear the
fault. This causes the faulted instruction to be skipped, with execution resuming at the following
instruction.
Because the fault handler is internal, you do not have to configure a fault handler to get this
behavior. In fact, even if a fault handler is configured, a suppressed fault will not trigger it.
GSV Identifies whether to enable the firmware supervisor.
SSV Value Meaning
0 Do not execute the firmware supervisor
1 Execute the firmware supervisor
GSV Identifies whether to maintain test edits on controller switchover.
Value Meaning
0 Automatically untest edits at switchover
1 Continue test edits at switchover
GSV Name of the controller.
GSV Identifies whether the controller is configured for redundancy.
Value Meaning
0 Not configured for redundancy
1 Configured for redundancy
GSV Identifies how the continuous task and the background tasks shared any unused timeslice.
SSV Value Meaning
0 The operating system will not give control to the continuous task even if
background is done (default)
1 Continuous task still runs if the background tasks are done.
2 The operating system will not give control to any tasks even if
background is done
GSV Percentage of available CPU (10...90) that is assigned to communications. This value cannot be
changed when the keyswitch is in the Run position.
