Context
The SmartLogger can be connected to an EMI that supports the standard Modbus-RTU
protocol. One SmartLogger can be connected to and manage only one EMI.
Devices from different vendors may support different protocols. To obtain information from
the connected EMI, correctly configure the protocol on the WebUI of the SmartLogger based
on the document delivered by the vendor.
For the definition of the RS485 communications cable for the EMI, see the instructions
delivered with the EMI.
There are six RS485 ports in the SmartLogger. For the port descriptions, see Context in
