Getting Invalid SLC/Micro Address Again
« on: October 04, 2019, 03:24:55 AM »
BETA 33 -

PLC 5/20  Using Serial DF1 protocol for HMI


Archie I have two compact gauges reading N22:134 and N22:135 respectively They are working fine but I decided to put an analog value display to the gauge front reading the same words.
The Analog display toggles between the correct value, then to the error message "Invalid SLC/Micro Address - 0"  about every 5 seconds.

Click on gauge image to see error displayed at 1 sec interval

Check all of your PLCAddress* properties. You have a "0" in one of them.

Sure enough, I missed one-- . Thanks Archie!.  But could you explain why it would read the value correctly every 5 seconds?

The display time for an error is 5 seconds, then it reverts back to the previous display value. So if you had a valid address in PLCAddressValue, but an invalid address in PLCAddressVisible it would show the error every 5 seconds and revert back to the valid display
