7.3. « Trigger » mode

7.3.1 Operation

Relaying alarms from "n" ARF50s. Exchanges are limited to changes in state of the inputs of the master modules.
When not relaying alarms, the products are in standby to optimise power consumption.
• The Trigger mode consists of 1 to 16 masters and one RF slave.
• The masters are configured to exchange with the RF slave when its inputs change.
• Each input of each master is configured independently (digital input: level/analog input): threshold).
• At exchange an exchange is made with the RF slave
• During the exchange, the active inputs transmit their values and the other inputs a "0".
• The RF slave memorises all the values sent to it.

7.3.2 I/O allocation

• Slave
The digital outputs of the slave are a logical OR of the N digital inputs of the masters:
SA = OU(E[M_1]A ... E[M_N]A)
SB = OU(E[M_1]B ... E[M_N]B)
SC = OU(E[M_1]C ... E[M_N]C)
SD = OU(E[M_1]D ... E[M_N]D)
The analog outputs of the slave are the MAX of N analog inputs of the masters:
SX = MAX(E[M_1]X ... E[M_N]X)
SY = MAX(E[M_1]Y ... E[M_N]Y)
• Master
For each exchange between the master and the slave, there is a repeat of inputs of the slave on the outputs of
the master.
