Parameter Configuration For Interconnection; Operation Mode Selector (Oms) Functionality - DITEC DAS200TRF Technical Manual

12.2.3 Parameter configuration for interconnection

i
NOTE: Do not connect the operation mode selector (OMS) before the configuration of
6C is done on all MCUs.
One of the operators has to be the main MCU (MCU-1). The main MCU shall have the value 01 in
parameter 6C. The other interconnected operator shall have ascending values in parameter 6C.
When the configuration is done break the power on all the interconnected operators. Connect
the OMS, turn on the power. The main MCU is the control unit that holds the parameters to the
operation mode selector (OMS).

12.3 Operation mode selector (OMS) functionality

Check how to install interconnected units before configuring the operation mode selector (OMS).
See section 12.4.
All functionality regarding the operation mode selector (OMS) is programmed through the MMI on
the main MCU-1 (has parameter 6C= 01).
There are three (3) different types of configurations for MCU and OMS.
The "configure parameter" shows which parameter to change from the default setting to obtain
the function described, the parameters in the parenthesis shall represent the default values.

• AUTO= no use of terminals 9 ÷ 15 of plus module DAS902MP;
• Not in AUTO= use of terminals.

One MCU and one OMS. MCU is controlled
by the OMS
Configure parameter MCU, b5=0, b6=1
(6F=01, b3=40, b4=01).
One MCU with DAS902MP and one OMS.
OMS controls MCU when DAS902MP is
in AUTO.
When DAS902MP is not in AUTO, DAS902MP
controls MCU and OMS shows active mode
selection.
OMS is flashing once every 5 second to show
that it is remotely overridden. When the OMS
is remotely overridden it is not possible to
change its mode.
Configure parameter MCU, 97=01, b5=0,
b6=1,(6F=01, 9A=30, 9b= 01, b3=40, b4=01).
Two MCU, one OMS and one DAS902MP
connected to MCU-1.
OMS controls MCU-1 and MCU-2 when
DAS902MP is in AUTO.
When DAS902MP is not in AUTO, DAS902MP
controls both MCU-1 and MCU-2.
OMS is flashing once every 5 second to show
that it is remotely overridden. When the OMS
is remotely overridden it is not possible to
change its mode.
Configure parameter MCU-1, 97=01,b5=0,
b6=1,(6C=1, 6F=01,9A=30, 9b=1, b3=40,
b4=01).
Configure parameter MCU-2 6C=2, (6F=1).
