Hello all,
currently I’m migrating a SCADA to Igntion and I have to communicate with SLC-5/Micrologix 1400 PLCs. I have little experience with these PLCs, so I wonder if, performance wise, it is the same to read an Int/DInt, (HmiBool1 or B3:0, for example) and then create memory tags for the boolean values using an expression like getBit(HmiBool1, 0) or it is better to read the bit directly using the notation HmiBool1.0 or B3:0.0 on the tag path.
To write boolean values, I think I will use the direct bit access, in order to write to a tag and make the audit easier to read.
Any advice?
Thanks
