800xA with AC800M - the complete path of an I/O signal in Control Structure
in our plant we have been using for years only AC450s with 800xA. Now I have to create a small application on AC800M DCS and integrate it into existing 800xA. I've ordered the PP Libraries to keep the faceplates and graphic elements similar to those of 800xA for Advant Master, so the operators should be satisfied. On the other hand, there is a problem with our maintenance staff. They got used to hover the mouse over a graphic element representing an I/O signal and see the complete path to the I/O channel in the control structure. The name of the remote I/O station comprises the names of a room and a cabinet, so they know at the first look, where the physical interface is located, e. g. [Control Structure]Root/Network 11/Controller1/Remote IO/AF100_1/Room1_Cabinet5/Pos04_DI800/Ch 02/SignalName. Is it possible to have it that way with the AC800M? Is it possible to write the AC800M application (using either CBM or Function Designer) so, that the objects corresponding to the SignalInBool, SignalInReal and similar FB or CM would be created under Hardware branch rather than under Applications, eventually rather than in the Functional Structure when using Function Designer?

Short Answer : No
Longer Answer : The P&P Library does not use SignalInReal, SignalInBool etc. There is a one-for-one match for AC400 elements in the library, so you use AIS01, DIS01 etc
Connections between IO points and the AIS01 function blocks are done using variables. You could name these variables to describe their path and location, BUT, I dont think there is any way you could make the name of these variables appear on a tool tip. The OPC server cannot see the name of a variable connected to the IO parameter of your function block.
P&P Library blocks are designed to be programmed using FBD. This makes AC800M programs look like AMPL programs. You will need to check the release notes to see if Function Designer is supported. I suspect that it is not.
