MC4x error status
Hi,
Is there any way to read the error status of MC4x? I believe when error occurred a system message would show up. But is there any channel can be used to identify what error detected?
For example, how do I retrieve the error on DOUT HS+LS?
Regards,

If your MC4x is connected in a multi master to an MD4 or MD3, then you will see a dialog box on the master display.
The MD3/MD4 display pages property "Show messages" must be set to all.
You can also connect with IQANrun, and when you click on the module, you will see all channels that are in error status listed.
But I guess the question is really about using a channel for the error
If you want to read the status of a channel in the application, you use the status operands, in Object list or Qcode
With Qcode, the syntax for reading DOUT open load would is for example:
Result := StatusOf(DOUT-E) = stOpenLoad
If you do want to react on any type of error, it is almost always a good idea to just look at the status type Error
Result := StatusTypeOf(DOUT-E) = stError
The system System Information Channel can be used to read a more general "Active error level", this will not pinpoint the channel that has the error, but rather just say that there is some error detected by the module.
