There are some rules for the Object flag set or clear for each bit by the controller.
The rules below are also applied to Event data.
• When the controller is in Non-Executing mode, the object flag is always all
0.
• When the controller is in Executing mode and there is no configuration
file, only the Online flag in the object flag is set.
• When the controller is in Executing mode and there is a configuration file,
the flags in the object flag are set according to the upper byte of the
configuration files.
Object Flags for Binary Input
Bit Offset Name Description
0 ONLINE In Series A controllers:
0 when the controller is or was in Non-Execting mode.
1 when the controller is or was in Executing mode.
In Series B controllers:
0 when the controller is or was in Non-Execting mode.
1 when the controller is or was in Executing mode and the configuration file does not
exist. May be 1 when the controller is or was in Executing mode and the configuration
file exists.
1 RESTART Always 0. Not used.
2 COMM_LOST Always 0. Not used.
3 REMOTE_FORCED Always 0. Not used.

5 CHATTER_FILTER Always 0. Not used.
6 reserved Always 0. Not used.
7 STATE Reflects point state of Binary Input point.
Object Flags for Double Binary Input

1 when the controller is or was in Executing mode.
In Series B controllers:
0 when the controller is or was in Non-Execting mode.
1 when the controller is or was in Executing mode and the configuration file does not
exist. May be 1 when the controller is or was in Executing mode and the configuration
file exists.
