32.2 Function Master
Software functions of ATR620 include operating as Master. This feature
allows serial communication of several controllers to control more zones
of the same kiln. Function is enabled entering 0 on parameter 50. Master
will communicate Start/Stop of cycle and setpoint values to the
connected slave units (which must be configurated for remote setpoint
on parameters 1 and 5). Communication follows the broadcast mode: all
controllers receive data. If Waiting function is enabled on Master, it will
read process values of the first 16 connected controllers (slave address
1 to 16 on parameter 50) and it will check eventual delay of any
connected zone.
