I've been doing some testing with a BL block and it appears that it can't use DR blocks as inputs. Is this correct or is there some way to get around that?
I'm trying to use these BL's to do some simple logic in the SCADA instead of in a PLC (it's a validated environment and SCADA changes are easier to get the paperwork approved for and less invasive to existing operations), so I want to re-use the existing SCADA tags which are reading from the PLC, but those are DR's and not DI's.
Any assistance appreciate,
