s7-300 with comsoft df profi II

How long do you think the equipment will be unavailable? Have you gotten any simple program to work using the Express Vis?

I have a smaller PXI with the Comsoft card in it, and a Siemens PLC in the lab.  Yesterday I finally got all the stuff together to try working on it again.

 

I'm getting data, but not all of it.  I'm getting the forth byte in a Double Word value.

 

I used parts of the Comsoft library, but not the Express VI.  I used the Example to create a program using the Initialization VI, and then reading/writing VI, then closing.  I'll try the Express VI to see how that works.

 

Thanks for the help.  I'll post an update later today.

I've the problem solved.  The PLC was not spreading out the 32-bit value over 4 bytes.  I finally found the command that gets this done.

 

Thanks for all the help.
