How can an unconnected indicator read an FP digital input?

[cdreike]

SYSTEM DESCRIPTION:

A Dell desk top computer with a Field Point system attached. There are a variety of modules including analog input, 2 digital inputs, relay out, Strain gage input, quadrature input. The system is running XP. The Labview program is written in v6.1.

PROBLEM

In an application written by others, I have found 4 front panel indicators that react to Field Point digital inputs. On the block diagram, the indicators are not wired to anything. They have no local variables and no global variables associated with them. How can they be reacting to the FP inputs? The problem is that one of the indicators reacts to the wrong input and I need to fix it.  See "In(Rescue)Limit, In(Cargo)Limit, 4067 Out Limit and EStop".

Also, when the vi is launched, it starts up the FP system and the vi has no FP vi's in it and none of the sub-vi's have any FP vi's in them either. Any clues how this could be working?

I have attached the vi. There are other vi's in this project, just too many to include unless more information is needed.

Thanks,

Chris,

It doesn't look like you attached the VIs.

You can use front panel DataSocket binding to link an indicator or control to a FieldPoint ethernet item. Right-click on the indicator and choose Data Operations>>DataSocket Connection.
