CAN Teamwork + RS485 Monitoring
Networking Teamwork Monitoring
Protocol CAN Modbus-TCP
Description
One teamwork network
supports a maximum of
32 units. On the
Teamwork Settings
screen of the display
modules of the first and
last units, set Enable
teamwork CAN resistor
to Yes.
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.
Connect the
COM/FE port on the
main control
module of the last
smart cooling
product in each
group to the RS485
port on the host.
