Model 10C 1.0 Description Physically, the Detcon Model 10 Facilities Module (FM) is a Model 10C board assembly with some slight variation in board component population1 and with different firmware, compared to the Mod 10C Single Sensor Controller (SSC) board. The Detcon Model 10 Facilities Module is designed to be used primarily for gathering data from multiple Mod10 Single Sensor Control modules.
Model 10C The SSC settings cannot be monitored nor can they be changed through the FM operator interface. The FM has its own Alarm configuration and function. The FM takes the alarm conditions from its group of slave SSC modules and performs a logical-OR to accumulate a residual alarm state. That is, if any alarm state is ON, the logical-OR of alarms will result in that alarm being ON in the FM. The FM only evaluates the alarm status given by each SSC.
Model 10C To silence an FM alarm relay, note that this is a separate configuration from the individual SSC alarm relay configurations which may be individually set per SSC module. An alarm relay output may be silenced if it is Silenceable and by following the Alarm Acknowledge or Alarm Silence procedure described under the Alarm Acknowledge section that follows. 1.2.

Model 10C the COS registers indicate a change, and then poll for all the 40000 data registers. Then write zero to the COS registers. A more complex RBE scheme is to only poll the registers, in response to COS bit indications, that have changed since they probably change only one at a time. Then acknowledge by writing the COS image back to the respective COS register; ie: a bit is set to 1 in the bit position where it is desired to reset an existing 1 bit.
Model 10C 2.1 Normal Operation While in Normal Operation of the Operator Interface, on the character display of the front panel is visible the RTU ID, also known as Modbus Address, of this FM. If the Fault LED indicator is lit on the front panel, there may be some SSC modules that are not communicating if the fault is not due to a fault on any individual SSC module. To see if there exists a communications fault or faults, press the ESC pushbutton.

This puts the FM operator’s interface in the “Program Mode”.
Model 10C 4.2.1 Latching The Latching selection is indicated with “LT=x” in the display where “LT=0” for Latching is OFF and “LT=1” for Latching is ON. 4.2.2 Energized The Energized selection is indicated with “EN=x” in the display where “EN=0” for Energized is OFF and “EN=1” for Energized is ON. 4.2.3 Silenceable The Silenceable selection is indicated with “SL=x” in the display where “SL=0” for Silenceable is OFF and “SL=1” for Silenceable is ON. 4.

Model 10C 7.0 Model 10C Backplane Pinouts Note that the RS485 Channel 1 is used for the Model 10 Single Sensor Controller to communicate as a Slave to a Master Host. If the Facilities Module is used, then the Master Host is the Facilities Module, connected from its Channel 1 RS485 to the SSC Channel 1 RS485.

Model 10C 8.0 Model 10 Facilities Module Backplane Pinouts Note that the RS485 Channel 1 is used by the FM to communicate to Modbus Slave devices: namely, MOD 10 SSC modules. Note that RS485 Channel 2 is wired to pins C7 and C8, for RS485 signals A and B, respectively. This second channel is the connection to the Master Host for the Facilities Module, on which the FM is a Modbus Slave device.
