Hello,
I hope ya’ll are having a good day. I had a question about address requests from a Modicon.
As far as communication to the device is concerned, will I add network traffic if I poll bits from a register (A) rather than polling the register and parsing the bits with expressions (B)?
A
Tag 1 = HR1000.0
Tag 2 = HR1000.1
Tag 3 = HR1000.2
B
Tag = HR1000
Tag 1 = getBit(Tag, 0)
Tag 2 = getBit(Tag, 1)
I thought I would check because I know that sometimes when an OPC polls it just grabs a whole block of registers. The device we are connecting to is a little delicate, and as convenient as it is to grab lots of individual bits into their own little tags, I wanted to get your opinions before I started faulting things all over town.
Thanks!
