Hey,
I'm new to the PanelView Plus communicating to a ControLogix. I've got a ControLogix program all written using UDT's wherever possible. I have a lot of analog and digital data to display on the PV+ (Approx 100 Dints, 50 Reals, 250 Bools). All of this data is coming from 4 UDT's (Controller based tags of course). The guy I'm working with on developing the PV+ tells me that I have to map all of this PV+ data in the ControLogix to one big block of Dints because the PanelView+ won't pick data from the seperate UDT's. He says he tried it before and crashed the PV+ comms. Am I correct in thinking that the data is transfered in blocks anyway so it doesn't matter? What's the difference if a block of the UDT transfers or a block from the Dint array? I've done PV+ using a SLC and never mapped any data into a special block or file just for the PV. And never had trouble with communications; so this ControLogix change seems strange to me. Is it?
Thanks in advance;
Patrick
