Hello all,
Apologies if this question has been answered before, I have done a quick search and couldn't find exactly my problem.
I am currently adding a Siemens PLC to our RSView SCADA and whilst i have set up the OPC server and have managed to get my tags done I am struggling with my alarms. The alarms from the PLC are in Word format and and I am trying to get them in bit format.
I have managed to get my bits by using db##,#.# but seem to recall that if I want to take a bit out of a word (I think it is called indirect address) I need to use db##.dbx#.# , is this correct.
If my terminology is not right or this is a very basic question please forgive me but I have had a headache over this all day.
Regards
Dave
