Memory Areas Appendix C
SR 25212 (I/O Hold Bit)
This bit is turned ON and OFF from a peripheral device.
A setting can be made in the PC Setup (DM 6601) to cause the status of this Bit to be retained even when pow-
ering up.
SR 25215 (Output OFF Bit)
When this bit it turned ON, all outputs will be turned OFF and the CPU Unit’s OUT INH indicator will light. Out-
puts will remain OFF even if output bits are turned ON by the program until this Bit is turned OFF again.
SR 25308 (Battery Low Flag) and SR 25309 (Cycle Time Overrun Flag)
A setting can be made in the PC Setup (DM 6655) so that these errors will not be generated.
AR Area
These bits mainly serve as flags related to CQM1 operation. The following table provides details on the various
bit functions.
With the exception of AR 23 (Power-off Counter), the status of AR words and bits is refreshed each cycle.
(AR 23 is refreshed only for power interruptions.)
