● If the Modbus-TCP/SNMP protocol is used, customers can purchase the NetEco (a LAN
switch is required) or a third-party NMS as the monitoring system.
● If the number of units in a group is greater than 16, FE teamwork needs to be
implemented by group. For example, if the number of units under teamwork is 18, they
can be divided into two groups, for example, 9+9, 16+2, or 10+8.
Connecting units with odd numbers: Connect the FE_1 port of the unit with
an odd number to the FE_2 port of the unit with the next odd number.
Connecting units with even numbers: Connect the FE_2 port of the unit with
an even number to the FE_1 port of the next unit with an even number.
Connect FE_2 of No. 1 unit and FE_1 of No. 2 unit, and connect the remaining
FE_1 and FE_2 of the last two units.
