Vijeo reading proworks inputs

[Jalber]

I am converting a CTC hmi to a Vijeo project.  The previously configured alarms looked at the input address 10001 in Proworks.  My understanding is that the 10001 address is an input address assigned to the input card.

I cannot read the 10001 address using the %M10001.  When I configure Vijeo to use either the %I or the %IW, I get a config error.

Is it possible to read an input address 10001 or should I remap?

Try %M0001. I think that will work.  What is the PLC?

Hi Jalber,

"Vijeo" is the brand name of many Schneider products, so I'm not sure which one you are referring to, but many HMI and SCADA products cannot read physical I/O addresses directly. Please copy the data in the PLC to memory adresses to be able to read them.

Jalber,

Here is a cross reference between the Modbus address and the equivalent Control Expert IEC address. Vijeo Designer can use either depending on the driver selection. If you selected IEC syntax, then you will see the references as %I, %IW, %M, %MW (also if you checked the 0 based controller you will be off by one address as a 984 controller is 1 base). If you are using the Modbus/TCP driver you need to set it up as IEC61131 Syntax not checked, Unit ID 255, Low word first, and low byte first under variables. You will then see the 0x, 1x, 3x, 4x references in Vijeo designer instead of the IEC %I when you create a variable.

  100001 = %I1

  000001 = %M1

 300001 = %IW1

 400001 = %MW1
