FE Teamwork + RS485 Monitoring
Networking Teamwork
Protocol MAC_CAN
A teamwork network
Description supports a maximum of
16 units.
•
Connect the COM/FE port on the main control module of the last unit in each group to the
RS485 port on the host.
• Customers can purchase the NetEco (an ECC 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.
If the length of a network cable in the FE teamwork is greater than or equal to 100 m, use the
group-based ring networking mode.
1. 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.
2. 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.
3. 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.
Monitoring
Modbus-RTU
It takes 3 x n seconds to collect data from n units. If the
time required for the host to collect data from all units
does not meet the performance requirements, group the
units.
•
If units are not grouped (n = 1), set RS485
monitoring grouping to Enable on the Modbus
Settings screen for each unit.
•
If units are grouped (n > 1; recommended: n ≤ 4), set
RS485 monitoring grouping to Enable on the
Modbus Settings screen for the unit with the COM/FE
port connected. Retain the default setting (Disable)
for other units.
