9.2.2 How to Detect Mode, Status and Alarm
Each NPAS POU has mode, status and alarm status information.
In addition, each device label variable has status information.
This section describes how to read this status information in Logic Designer or from
a control application.
Details on mode, status and alarm can be found in Logic Designer’s NPAS POU
online help documentation.
● Data Type of Mode, Status and Alarm of NPAS POU
In an NPAS_POU, mode, status and alarm status are stored as DWORD-type data,
while statuses of device label variables are stored as WORD-type data.
DWORD-type data comprises 32 bits while WORD-type data comprises 16 bits, with
each bit representing a specific mode, status or alarm condition and turned on when
its associated condition is true.
