Does anyone have much experience with setting up a Click PLC to communicate with Ignition? I have setup the port1 connection to my desired address and believe i setup the modbus tcp section for port 1 properly as well(port 502). But i am unable to connect to my PLC. It cycles between connecting and disconnected. Apologies ahead of time as this is my first time working with these PLC's ---

Check your gateway logs for any errors. Are you able to ping your PLC from the server that Ignition is installed on? Have you confirmed that your server is on the same subnet as the PLC? Or that your IT department has routing rules in place to allow your gateway to talk to the subnet that the PLC is on? ---

Sorry just to clarify. I'm currently running a test gateway of ignition on my computer to prove out some things. But yes i am able to ping the PLC from my computer. But ignition is failing to connect. ---

Check your Ignition gateway logs. Your laptop firewall might be blocking the Modbus comms specifically. Also, have you configured any tags for the device in Ignition yet? I think that these PLCs will kill the connection quickly if its not actively requesting any register data. I know the BRX series does this. Try defining a single tag to look at holding register 0 or something like that ---

Funny, I just connected to a Click Plus PLC literally 5 minutes ago for the first time. It connected just fine for me. I went to `configure com port` and did the typical IP address stuff. Did you make sure to save your changes to the PLC? Can you ping the device? ---

I believe i did everything correctly on my end within the PLC. Setup \> Com port 1 setup \> Entered the desired IP addresses and what not. Downloaded and saved. And yes when plugging into the desired port i am able to ping the PLC from my device. But i'm getting nothing within ignition. I also attempted to setup a few addresses to the best of my knowledge using the modbus addresses within the address picker. But i'm still getting no luck. ---

Check your ignition logs. Are there any errors present? There should be something at least saying its attempting to the Click. ---

Are you referring to the logs related to this specific device? If i go to device view for the click plc and set my log activity min level to TRACE i do see an "Error during connect" ---

Did you make it for TCP or UDP? Should be TCP port 502 inbound and outbound. ---

Are you straight wired from PC -\> PLC? Like just a patch cable connecting the two? If so, it probably considers the connection a public connection. Make sure public network is allowed in the firewall rule. Also, if this is a windows computer you _might_ need a restart after the rule setup. ---

Unfortunately, I can't add much to the troubleshooting side of this, but I do have two of these that I added to a couple of... I'll just call them 'legacy'... assembly lines. I didn't have to do anything special on either end to get them to work, IIRC. Let me connect up to one of them and look at the config for you, as much as a refresher for me, as a sanity check for you. 🙂 [Next page](https://forum.inductiveautomation.com/t/click-plc-connection-into-ignition/104329.md?page=2)
