Title: Clear data when driver is disabled
Post by: MrPike on November 06, 2015, 07:08:17 PM

Archie, is there a way to clear the data displayed when the Modbus driver  DisableSubscriptions = True?  I would like to clear the data  to prevent someone from reading the data which is not being updated and possibly causing operator confusion.  Thank you.

You would have to write code to clear everything on the form after disabling subscriptions. For example:

ModbusTCPCom1.DisableSubscriptions=True
BasicLabel1.Value=""
DigitalPanelMeter1.Value=""

Hey Archie, I did try this method and the only problem I have is that when the DisableSubscriptions returns to "True", the text will not change from what I set it to unless the data changes...so if I have the same value in the device, I still see the text "----" (this is what I set it to on false).  Is there a way around this?  Maybe set an "ElseIf" to the datasubscriber value? I'm not sure how to access the Datasubscriber values.  Thx
