We have two Yaskawa VFD's controlled by their IQPump controller. We are trying to get the Yaskawa controller to communicate with Trane Tracer Summit. We have installed a Polarsoft FreeRange Router mini v4.08 to convert the Modbus to BacNet but still cannot see any data coming from Yaskawa. I am stuck in the typical battle of subs where Yaskawa swears that their equipment is fine and Trane swears that they can't see data. I have put a WireShark packet sniffer on and can see the Polarsoft router give a BacNet "I-Am-Router-to Network" but no datapoints from Yaskawa are being pushed out. I cannot get into anything beyond the PolarSoft IP setup screen (is there any drill down setup menu?) to check if there is something else that needs to be set up. I think this is a PolarSoft issue. Any help would be appreciated. Tks.
