4.2.1 Register – Detcon Type
Both register maps include this Detcon Type and is a unique identifier of the type of device and associated
register map. A controller can therefore perform a search and determine what Detcon devices are present on a
Modbus™ system.
4.2.2 Register – Alarm Outputs
There are four registers that control the four open collector Alarm Outputs. A value of 0 written to these
register will turn the Alarm Output off (not grounded). A value of 1 or non-zero value will turn the Alarm
Output on (grounded). If the secondary Alarm Output registers are enabled, the registers are duplicated and
writing to either set will turn on or off the Alarm Outputs. The current value of the Alarm outputs can be read
at any time. The default value for all Alarm Outputs upon power up or reset is 0.
