Overview

Installation steps

  1. install RapidPlan and RTR-Webapps megadebs and licenses.

  2. Under the controller OS network settings, assign a hard-coded IP address with network mask to the interface to be used as the Profinet port. The IP address should be in the same subnet as the PLC.

  3. Go to RapidPlan Control Panel and turn on Profinet under settings by selecting the protocol and the network interface configured in step 2. Profinet can be enabled without a loaded project. However, in order to export ID lookup table, a project must be loaded.

  1. Reboot. Profinet interface is enabled.

Startup behavior when connected to multiple interfaces in the same subnet

If a RTR controller has multiple Ethernet IP addresses that are connected to the same subnet, and Profinet interface is enabled among them, for example:

in order to prioritize Profinet communication, a user needs to open and edit the /etc/sysctl.conf file, to add net.ipv4.conf.all.arp_ignore = 1 at the end of the file. Then save and reboot the RTR controller.
