3.12.4.4 Connecting the Monitoring Network Cable

The smart cooling product supports both RS485 and FE monitoring.

3.12.4.4.1 Connecting the FE Monitoring Network Cable (SNMP/Modbus-TCP)

The FE monitoring and FE teamwork control use the same network cable. For the
connection method, refer to
3.12.4.4.2 Connecting the RS485 Monitoring Network Cable (Modbus-RTU
Protocol)
When monitoring smart cooling products over northbound RS485, the EMS needs
3 seconds to collect data from one smart cooling product. Therefore, the time
required for collecting data from N smart cooling products in a group is 3 x N. If
the data collection time is longer than the performance requirement, you can
divide the smart cooling products into several groups. For example, if the EMS
needs to finish data collection in 12 seconds, you are advised to group smart
cooling products by four and connect the COM_IN port of the main control
module of the first smart cooling product in each group to the RS485 port of the
EMS.
Procedure
