Applies To:
  • CitectSCADA 4.xx, 5.xx
Summary:
The Citect ASEA driver uses ABB's EXCOM protocol. It has been noted that incorrect data is displayed on CItect using this driver under certain circumstances. Why? 

Solution:
There are two possible causes for the problem:

1. The Citect driver did not handle long breaks in communications very well. Ci Technologies have updated the ASEA driver and this will be released with Citect V5.01. The latest version can also be found on Ci Technologies FTP site.

2. The Masterpiece 200 will respond incorrectly if the latest firmware is not used. The firmware should be the following version or later: QMP-280 SV1W6.0-6
