Let the leak sensor be connected to the '''input 1''', and the '''relays 1 and 2''' control the ball valve actuators. '''Relay 3''' controls the warning lamp or buzzer. When wetting the leakage sensor '''relay 1 and relay 2''' are closed and the actuators close the ball valves. '''Relay 3''' closes and switches on the buzzer. '''Input 2''' will be programmed to reset the alarm and open the ball valves. | |||

<syntaxhighlight lang="bash">modbus_client --debug -mrtu -pnone -s2 /dev/ttyRS485-1 -a1 -t0x10 -r384 $(printf ' 0%.0s' {1..64})</syntaxhighlight> | <syntaxhighlight lang="bash">modbus_client --debug -mrtu -pnone -s2 /dev/ttyRS485-1 -a1 -t0x10 -r384 $(printf ' 0%.0s' {1..64})</syntaxhighlight> | ||
Apply in our case, the mode when the input state is repeated every 20 minutes, for this write in the register 9 value 5 (control in accordance with the mapping matrix, after 20 minutes to re-simulate the input state), and the rest — the value 4 (control in accordance with the mapping matrix). | |||

To enter the leakage sensor (input 1) use the mode 1000 (8) — turn on when the circuit. [[File:Mm_1000.png|frameless|270px]]<br> To enter the reset button (input 2) use mode 0100 (4) — turn off when closing. [[File:Mm_0100.png|frameless|270px]]<br> | |||
On the map mapping-registers we determine that to enter 1, you need to write the value 8 in the registers 384, 385, 386, and to enter 2 — write the value 4 in the registers 392, 393, 394: | |||

Checking: close input 1 and iGND and leave it closed. Relays 1, 2 and 3 must be switched on. Then we close and open the input 2 — all three relay relays are off. Wait 20 minutes. Since input 1 remains closed (leakage is not eliminated), relays 1, 2 and 3 will switch back on after 20 minutes. | |||
Leaving input 1 closed, turn off and turn on the relay power: after 20 minutes, relays 1, 2 and 3 will turn on again. | |||
