Chapter 4 Input/Output Instructions (MSG, GSV, SSV, IOT)
CanUseRPIFrom
Producer
DINT 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
ControllerLog
Execution
Modification
Count
DINT GSV
SSV
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
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.
ControllerLog
TotalEntryCount
DINT GSV
SSV
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.
DataTablePad
Percentage
INT GSV Percentage (0...100) of free data table memory set aside.
IgnoreArrayFaultsD
uringPostScan
SINT GSV
SSV
Used to configure the suppression of selected faults encountered when an SFC action is
postscanned. Only valid when SFCs are configured for automatic reset.
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.
InhibitAutomatic
FirmwareUpdate
BOOL GSV
SSV
Identifies whether to enable the firmware supervisor.
Value Meaning
0 Do not execute the firmware supervisor
1 Execute the firmware supervisor
KeepTestEditsOnS
witchover
SINT GSV Identifies whether to maintain test edits on controller switchover.
Value Meaning
0 Automatically untest edits at switchover
1 Continue test edits at switchover
Name String GSV Name of the controller.
Redundancy
Enabled
SINT GSV Identifies whether the controller is configured for redundancy.
Value Meaning
0 Not configured for redundancy
1 Configured for redundancy
ShareUnused
TimeSlice
INT GSV
SSV
Identifies how the continuous task and the background tasks shared any unused timeslice.
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
TimeSlice INT GSV
SSV
Percentage of available CPU (10...90) that is assigned to communications. This value cannot be
changed when the keyswitch is in the Run position.
