Summary:
Citect Time Stamped Alarms do not always match what the PLC reported. 

Solution:
It appears that if more than one high resolution alarm occurs in one scan and they are from different I/O Devices, then Citect may complete the display and logging of the time stamped alarms using old data - before all of the I/O Devices have returned with their new data.

CIT has confirmed this to be a problem in Citect for Windows versions to 5.01. This problem has been fixed in version 4.20 Spk K and 5.01 Spk A.
