e. update the 200n network
RMC units are controlled by a central 200N
control and monitoring unit. The Update
Network Function in the 200N software
must be triggered in order for the 200N to
recognize new or changed RMC units. Until
this software function is run, the 200N will
not control new RMC units.
1.
energize all rmCs in the network.
Confirm that the RS-485 network is
complete (all RMC and RMM2 units and
the 200N are connected to the RS-485
bus), and that the power to each unit has
been turned on.
2.
use the 200n system software to
update the network.
Note: When the 200N is first powered,
it automatically runs the "Update"
function.
Run the 200N "Update Network"
software function to trigger it to
recognize new RMCs. The 200N
Installation and Operation Manual
(H56583) describes this software
function in detail.
3.
if necessary due to problems or
questions, check function of individual
modules.
• V erify that a RMC is functioning by
confirming that the power LED is
illuminated and the communications
LEDs are blinking.
• C heck all connections.
• C heck that all RMC modules are
securely seated on the DIN rail.
• C onfirm that the RMM2/RMC network
does not have any duplicate RS-485
addresses.
