Timestamp in WinCC Flexible OPC Server

5/4/2009 11:35 AM	Rate (0)
kid_26 Posts: 37 Rating: (0)	Hi all, I have a question regarding WinCC Flex OPC Server. Does it support ms timestamp? We have a data acquisition project in which the timestamp in ms is required to be displayed to the user. Thanks for your feedback.

kid_26 Posts: 37 Rating: (0)	Hi Manfred, I am actually referring to the timestamp display of WinCC Flex OPC Server in milliseconds instead of a normal seconds since I need to acquire data in the rate of 1000 samples/sec.

kid_26 Posts: 37 Rating: (0)	Hi ZAK, Thanks for the reference. I could not find what the max update/scan rate of the OPC server is. Do you have any idea on this? The required sampling rate for the data acquisition system is 1000 samples/s. Therefore, I assume that the update rate is gonna be 1 ms. Please advise. :)
