In a project we have lot of MCCBs connected to IFMs that are connected to IFE and then to PAS800L (see attached). The PAS800L is connected to Siemens S7 PLC. The main reason for using PAS800L was to reduce the number of devices that needs to be polled. But it looks like PAS800L is just working as a gateway and not a server so you still have to poll the data from each device (MCCB). Is that correct?

Thanks
