14.1.2 Configuration update delayed
The controller activates this alarm if an operator and/or external equipment is changing the controller configuration too quickly. For
example, a programming error on a PLC can create a storm of Modbus changes.
To protect the controller's internal memory, the excess configuration changes are not stored immediately. The delay can be up to 10
minutes. If the controller loses power during this time, the changes may be lost.
The alarm is always enabled. The alarm action is Warning. The alarm is automatically acknowledged when the configuration
changes are stored. The alarm parameters are not visible.
