What can cause a FieldPoint Hardware, Discrete Controls Oscillation Problem to occur for each of Five Separate Modules?

[neilr 528]

Manual Controls (DISCRETE STATE = TRUE OR FALSE) Are Used To Activate Remote Relays, Each One At A Time and at different times under operator control.

If single click of mouse on discrete control button is used single transition of discrete FieldPoint output occurs with no oscillation of the output of the particular discrete FieldPoint module, either a FP-DO-400 or FP-RLY-420.

Problem: If discrete control button is double clicked using a mouse control by accident instead of single clicking, FieldPoint module output oscillates (or chatters or rings) for several to ten or twelve cycles instead of just single transition? See Figure 1 -

When the commanded over an Ethernet link to a FP-1600 Ethernet transceiver module, why does a discrete state digital output FieldPoint Module oscillate and what can be done either in hardware or software to correct this incorrect response? This occurs with the following modules when the control button is double clicked.

Neil,

This is not a typical problem I would expect to see caused by a hardware or FieldPoint driver problem. The key here is that it only happens with double clicking on the mouse button. I have the feeling this is the result of improper mouse settings that are causing the program to treat the double click as multiple single clicks. Go to the Control Panel>>Mouse settings and adjust the Double Click settings. You may also want to check the settings on each control and set the control for switch when released or latch when released (depending which is more appropriate for your application).

Regards,
Aaron

Aarron,

Thanks I'll pass that on to our team and we'll try that. I'd thought there was an approach like this but no one had found it yet.
