If a Symbol Set object contains a Cicode expression that references a PLC and that PLC goes offline, the symbol set object will not immediately display a hashed pattern (#COM). Also if the object is of type Multi-State and accesses multiple PLCs it will not display a hashed pattern until all PLCs are offline.  

CIT has confirmed this to be a problem in Citect for Windows versions 5.30 Service Pack A to 5.40 Service Pack A. This problem has been fixed in version 5.41.
