Summary:
The Honeywell Sx driver uses a third party's (Proconex Corp) set of programs (API) to communicate via a special card to the Honeywell DCS system. These files have been updated. 

Solution:
The new parameters in vsmg.cfg allow the user to set the cache time (in seconds) and the thruput rate (in attempted transactions per second) for the Proconex High Level Driver, Vsmg.exe.

The parameters are:

cache_in_secs = xx; (default is 10 seconds, range is upto 60 seconds)

thruput = xxxx; (default is 1000, range is 500 to 2000 transactions)

This enhancement will be available in version 2.02.00.000 and included in Citect 5.21 Driver Pack B
