4.6 Connecting an EMI

4.6.1 Connection Description

There are two types of EMIs. One is a standard EMI that supports Modbus-RTU, and the
other is a split-type EMI that consists of various sensors.
The SmartLogger connects to a standard EMI that supports Modbus-RTU or a split-type EMI
over a COM port and connects to a current- or voltage-type sensor over an AI port. The
SmartLogger2000-10-C/11-C connects to a PT100/PT1000 temperature sensor over a PT port.
The connection mode depends on site requirements.

 If the SmartLogger communicates with the SUN2000 over PLC, ensure that the SUN2000 with PLC
is used.

If the SmartLogger2000-10-C communicates with the SUN2000 over PLC, one
SmartLogger2000-10-C can connect to a maximum of 80 SUN2000s over the built-in PLC CCO. If
the SmartLogger2000-10-C also connects to an external PLC CCO over the COM port, one
SmartLogger2000-10-C can connect to a maximum of 150 SUN2000s.
The recommended connection methods are as follows:
 Connect over a COM port if a COM or AI port is to be connected.
