Notes on troubleshooting
• LINK LEDs
Use the state of the LINK LEDs to check whether there is a connection to the Ethernet.
• Cables
Check that the pin assignment of the used cable is correct.
• Configuration
Make sure that the gateway is installed right next to the controller module and that no more
than 2 samosPRO gateways are connected. Also ensure that next to the gateways only a maxi-
mum of 12 i/o expansion modules are connected.
• Mechanical strength
Check whether the RJ 45 connectors are engaged by gently pulling on the EtherCAT connection
cables.
In case of high mechanical load, secure the RJ45 cable with a tension relief.
