I’m using a Digital Input channel on a GRV-MM1001 module to monitor for a button press, with the intention of reading the Onlatch from an OPC tag and clearing it after read. When trying to do this, I encounter an error (from Python asyncua code):
UA Error writing to tag ns=2;s=Devices/[scar_io]/OptoMMP/Modules/Channels/Start_Button/Onlatch on groov: "The access level does not allow writing to the Node."(BadNotWritable)
However, in the PAC Control edit window for that input, the “Allow Write Capability” checkbox is disabled, so I can’t enable it:
I thought that whatever was in the PAC Control strategy would take the place of these settings whenever it was uploaded and run – I noticed that a different channel name in the strategy would replace whatever I had set in groov Manage, for example.
From the toggles in the Public Access, I can see why one would get a different impression - that should probably be fixed to not display those counter and latch options outside of channel 0 and 1.
