I have a B&R CP476 PLC and would like to know how to communicate it with the 3IF681.86 module. It has an extension model 7ME020.9, in which the IF681 module is inserted. This IF681 module has two interfaces: 1x RS232 and 1x Ethernet. I was able to communicate with its RS232 interface, but I have no …

Hi, I assume you’re asking for the meaning of the configuration parameters from this config dialog, right? [image] The PLC doesn’t have a default IP. You can decide to set a own static IP address and network mask (not your notebooks IP, because every IP has to be unique inside a IP network) , o…

Hello Alvaro, you have to load two drivers onto the controller. You can find the files here: C:\BRAutomation\AS\System\V0240\SG3 [image] You can find further details here : B&R Online Help (br-automation.com) Regards Stephan

I managed to install these drivers, but how does it work for me to connect the PLC to the PC via Ethernet? I saw the manual but I didn’t really understand these IP parameters, whether to enter my PC’s IP or whether there is a default IP.

Thank you for your attention Alexander! So if my PC’s IP is 192.168.000.51, should I put something like 192.168.000.50 in my PLC’s IP address? And another question, should I perform any additional configuration on the Online settings screen of the Ethernet interface? [Captura de tela 2024-08-08 10…

Hi, [image] Álvaro Conti: So if my PC’s IP is 192.168.000.51, should I put something like 192.168.000.50 in my PLC’s IP address? Yes, if your PC’s IP setup is 192.168.0.51 with subnet mask 255.255.255.0, the you could use for example 192.168.0.50 with subnet mask 255.255.255.0 for the PLC (a…

Got it, I made these settings. Should I load them through another interface? And what would this PING be? A programming command?

Yes, you have to transfer the configuration into the PLC by a already working connection (I assume RS232)? PING is command line tool existing in (almost?) every desktop operating system to check if an IP address is reachable. Depending on the response of a PING command, you at least know if a devi…
