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

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.
