Hello all,

I 've been working with the CLICK PLC for the past couple of months, and I 've been struggling with hooking up an analog IO module. It seems pretty straightforward (just "click " it into place...), but the CLICK software refuses to acknowledge that the module exists. I haven't hot plugged anything, and both the PLC and the module are brand new. I can't imagine what I'm doing wrong. It might seem like a dumb question but... any help?

The PLC is C0-11DRE-D and the module is C0-4AD2DA-2.

I 've already tried:

1) updating firmware and software

2) ensuring that there's +24V to both the PLC and the IO module

Thanks.

Have you looked at the system configuration in the software? Main menu | Setup | System Configuration

You must select the modules that you have connected. This should be selected to match the physical setup and then download into the PLC.

Hope this helps you out.

Thanks for the reply, Garry.

Yes, I 've tried using the system configuration in the software. According to AutomationDirect's tutorial videos, the CLICK should automatically detect the modules that are connected to the PLC and display them in System Config--but mine isn't. Just to be safe, I disconnected from the PLC and selected the analog IO module manually. I reconnected to the PLC, downloaded the project, and got a System Config error when I entered RUN mode. If I try to open the system config when the PLC is connected, the software says there's a discrepancy between the PC and the PLC modules, so I need to pick which one to display. Basically, my problem is that the PLC isn't recognizing that the IO module is attached, so it won't run properly even if the software is configured for an IO module.

No, I didn't hot plug it. The software is the most recent version, as far as I know. I just downloaded it about a month ago.

The thing that baffles me is that I was having this same problem before, so I finally caved in and contacted the Automation Direct helpdesk directly. They concluded that I had a defective IO module and sent me a new one--but this new one doesn't work, either. I even got a new PLC, thinking that maybe something in my first one was fried, but nope, same deal. I'm really quite perplexed that something that should be so simple is turning out to be so troublesome.
