When using preview mode in Designer I am getting Bad_GatewayCommOff errors when writing values. Writing values works fine when in design mode using the tag browser window but when preview is turned on I get the error.
I am using Ignition 8.
Is there a parameter I need to enable to be able to write in preview mode?
You need to set the designer’s “Gateway Comm Mode”. Go to Project in the menu bar, then select ‘Comm Read/Write’. By default, a designer session will be in read-only mode.
