Instructions ECL Comfort 210 / 310, communication description
8.1.2 Recommended installation sequence
Before starting the electrical wiring and installation, it is
recommended that a network plan is made which specifies
ECL 485 address. If the ECL controllers are to be used in a
SCADA system, it is also recommended to include the
network plan.
1. Setup all the hardware with all cables and wires for the
controllers and room units
a. If necessary, ensure that terminations are present
2. Turn on power to the intended master controller, ECL
with ECL 485 address 15
a. If necessary, install application
b. Check that everything (including all addresses (ECL
485, Modbus & IP) is as intended
3. Turn on power to room units one by one
a. Check that the slave and ECL addresses are as
intended
b. Copy application if needed from controller.
4. Turn on power to the slave controller with the lowest
address
a. If the controller is without HMI, type B, the ECL must
be configured separately
b. If necessary, install application and make sure the set
ECL 485 address
Repeat step 4 until all controllers are installed.
8.1.3 ECA 30/31 application copy
The ECA 30/31 will automatically detect a new application
after 30 seconds when it connects to a controller that has
been updated.
The ECA 30/31 can hold 10 applications in its memory which
is sufficient for a network with one master and nine slaves.
The copying process takes about 2–3 minutes. If two ECA
30/31 are used at the same time the process will take longer
for the ECA 30/31 that started last.
