Casting Signal to GroupSignal - PCSDK

Developer Tools
1

Has anyone tried working with group signals from PC SDK for 5.07?

According to documentation, it is necessary to cast a signal to its particular type (DigitalSignal, AnalogSignal, GroupSignal) before reading or writing to the signal. When I attempt to cast to GroupSignal, it fails and says it is not possible. It only lets me cast to DigitalSignal.

DigitalSignal giMyGroup = (DigitalSignal)ioSystem.GetSignal(“giMyGroup”);

MessageBox.Show( giMyGroup.Value.ToString() );

giMyGroup.Dispose();

If I cast my group signal to a DigitalSignal, it allows me to access the value, and the value is correct. But if I try to write to the value when it is cast to a DigitalSignal, I get huge numbers written to the group signal in the controller.

DigitalSignal giMyGroup = (DigitalSignal)ioSystem.GetSignal(“giMyGroup”);

giMyGroup.Value = 1;

giMyGroup.Dispose();

Has anyone else seen these problems when working with group signals?

This was a bug in the initial 5.07 release. The next release will correct this problem. I tested a beta version recently and everything worked correctly.
