Unit continually
cycles on and off. Cross-references between tags, e.g.,
Var1 uses Var2 as maximum which in
turn uses Var1 as minimum. Remove one of the references or use
formula tags for indirect reference,
e.g., Form1 is equal to Var1 and used
in Var2 minimum instead of Var1.
Database is corrupted. Create a new database or send to
technical support for debugging.
Unit cycles power
after an operation. Most likely a program going in an
endless loop. Check if the operation launches program
containing loops with no exit point.
CF LED flashing
slowly. CF card corrupted or invalid. Format the card from Fieldbus
Gateway Manager using the Link >
Format Flash menu.
