If value is 0, control is disabled. If dierent from 0, it is the max. time that can elapse between
two pollings before the controller goes o-line. If it goes o-line, the controller returns to Stop
mode, control output is disabled but the alarms are active.
**
By writing 1 on this word, the eects of the writing are cancelled on all the Modbus addresses
from 3001 to 3022. Control therefore returns to the controller.
