Issue
When a remote I/O module goes offline the JACE will show an "NA" for the analog inputs but the binary inputs from a remote I/O module still show maintain their last value.
Product Line
TAC IA Series
Environment
- I/A Series MNB 1000-15
- I/A Series JACE
Cause
The BIs from a remote I/O module that is offline are going to an "NA" status if viewed from WorkPlace Tech. At the JACE an "NA" received from a BI object will be interpreted as a "fault" and the object will show its last value and turn orange to indicate it is in fault.
Resolution
When a Remote I/O module is off-line its AI and BI outputs will show as NA in WorkPlace Tech.
At the JACE an "NA" received from a BI object will be interpreted as a "fault" and the object will show its last value and turn orange. The BI can be set up to annunciate an alarm based on the fault condition in the JACE if necessary.
