Communication between iEM3155 and structureware automation server cannot recover

[Anonymous user]

Hi

I have a system with 10 iEM3155 connected to SAS through MODBUS.

During commissioning, there are several power outages occurred.

We observed that the communication between iEM3155 and SAS cannot be established after power recovery.

But since there are two devices involved, I'm not sure it's iEM3155 or SAS's problem.

Any one can share his or her experience with iEM3155 and SAS before?

Thank you

Hi Abon!

This is curious! I have this exact setup in my office and I switch it on/off many times per day. All seems to work fine. I've also have it working through an EGX over Modbus TCP. Are you closing your Modbus network with a resistor?

How are you configuring the AS? Did you try the Building BU Tech Support?

(sorry for all the questions!) 🙂
