We have 4 new HMS-EN2PB-R gateways that fault and lock out the Ethernet ports when the size of config file get to 350words. It can only be reset by using the USB/Webpage to delete the config. I seems that this is the size point were a second connection is generated on the Ethernet-IP side of the gateway configuration. The customer noted that this has not been a problem with the Prosoft gateways.HMS EN2PB Config.7z (15.6 KB)
Can you please try the following firmware on the device. You will need to connect though the USB webpage and upload the file.
Did updating the firmware resolve you issue?
