CM9001-EMS has 32 Sensor Registers that are useful for handling Sensor values and Alarms. Sensors can be updated with various values like Temperature, Humidity, Current, Power, Lux etc. The sensor values can be obtained from the TSM or external systems like KNX, Cbus, Modbus etc. Each Sensor is compared to a Setpoint, which is held in a Counter, so that if the sensor value exceeds the setpoint, a Virtual Input is activated, thus causing an alarm. Virtual Inputs can be any unused Input in CM9001 up to Input 96. Virtual Inputs are programmed like physical Inputs ie assign to Zone Types, activate On/Of Responses. A Virtual Input will ignore any activity on the physical input itself. Each Sensor can be assigned to the following parameters; “Responseâ€: Response or program that is activated when there is a change in Sensor value. Leave as Null Response if not needed. “Counterâ€: CM9001-EMS has 32 Counters. The Counter holds the Setpoint. Changing the Counter value similarly changes the setpoint. This allows setpoints to changed programatically from other events. Counters are non-volatile ie the value is maintained even when power and battery are removed.
Setpoints for each sensor are kept in Counter Registers. There are 32 Counters in CM9001-EMS which may be assigned. The Setpoint for each sensor can be set or changed by entering a value in the corresponding Counter. If a Counter is not assigned to a sensor that means the sensor is for monitoring only, and Virtual Alarm and alarm will not be triggered by the sensor, and KP04A wiill omly show the sensor value without setpoint. Counters are non-volatile, ie they maintain their value even after loss of power. The Counter value may be changed in KP04A using the Increment (Lock) and Decrement (Moon) keys. Flags Flags can be assigned to a sensor. A Flag has a binary state, ie it is either On or Off. A Flag which is assigned to a Sensor is used to enable or disables the Setpoint. Input. In KP04A if the sensor is monitored, pressing the SUN Key alternately enables and Disables the Virtual Input. If disabled, the sensor is displayed only without any setpoint. Flags are non-volatile, ie they maintain their value even after power off.If a Flag is not assigned to the Sensor, the Setpoint is enabled. Virtual Inputs Virtual Inputs can be any unused Input in CM9001 up to Input 96. A Virtual Input behaves just like a physical input, ie it has a Zone Type which triggers an Alarm Type, and activates On and Off Responses. In Alarms > Zones, the Virtual Input setting is seen. Note that a Virtual Input will ignore anything that is connected to the Input terminal. A Virtual Input need not be on the CM9001, or installed Slave or Local Expansion Modules so that it does not use up a Physical input. Last edited on Sunday Jul 8th, 2018 08:37 am by slychiu |
