4.5.1.3 PLC Event handling
The Advanced Station Settings form also enables you to configure which type of Events that should be
possible to mark as observed from the PowerMACS PLC using the outputs named ACKxxxEVENT.
Only the types checked in the Event types possible to mark as observed from the PLC frame will be
possible to acknowledge from the PLC.
From inside the PLC it is possible to see for which event types there exist unobserved events in the Event
Log. This information is available via the inputs xxxEVENT (SPCEVENT, ACCESSEVENT, etc.).
See View Event Log for a description of the different Event types and the PLC chapter: Station variables
for a description of the PLC inputs and outputs.
4.5.1.4 Conversion table
The Conversion table consists of a character mask name Significant positions and a list of up to 200
pairs of regular expressions, or Significant strings, and Code values.
The conversion table function starts by running the input string through the Significant position filter
resulting in a string consisting only of the characters at the specified positions of the input string.
