AB7670 - Communication problem with a safety relay

Hello,

I have an AB7670, Profinet IO side, we have a Siemens PLC, Ethernet/IP scanner side, it’s a safety relais (Allen Bradley 440C-CR30-22BBB with module 440C-ENET).
In RSLinx, the device is well detected.
I would like to read instance 100, of the safety relay ie 28 bytes (class 04).
After configuring the scan on the web page, the AB7670 device gets an error.
There is the MS LED which flashes red as well as the NS LED which flashes green ("No Ethernet/IP connections.
I tested config = 0, reverse the Connections Points, Point To Point,… without much results.

Thanks,
Mel

Hello Mel,

unfortunately i have to inform you that our Ethernet/IP Scanner Interface don´t support explicit messaging, it supports only implicit messaging (class 1 connection). But the 440C-ENET is only addressable by Explicit Messaging.

Do you have a device capable of reading this type of message ?

Hello Mel,

Sorry that i can not give you here a more positiv answer.

I wish you a great weekend.
