ProWORX NXT Issues Connecting to PLC

[dim5098]

Hello,

I am trying to use ProWORX NXT to view the logic of my Modicon Quantum 534 controller online. When I try to go online with it, it always times out. 

I am using a TCP/IP connection and my PC is in the same subnet as the controller in question. I can ping the controller's IP address just fine and when I use ProWORX NXT's Net Scan function, it recognizes that there is an Ethernet connection at that IP address but doesn't recognize it as a Modicon controller.

Weirdly enough, my PC can connect to another Modicon controller of the same type and in the same subnet just fine.

Can anyone help me with this issue?

HEllo Dim,

 

are you sure, that your controller was programmed with ProWorx NXT? - Maybe ProWorx 32, Concept or UnityPro?

Try to use OSLoader or ExecLoader to read the used Firmware.

I'm pretty sure it was. I can go online with the controller with other PC's on the same network using ProWorx NXT, just not this particular PC.

without any error code it's not really possible to find out the reason for that.  Did you try to establish the connection via ExecLoader?
