Bit Read relay status.
Bit Read input status.
A "TRUE" logic level on the inputs are
extended to minimum 5 seconds.
Unsigned Value = 310 → V3.10
Integer
Signed Integer Value = 0 ... 10.000 → 0 ... 10 Bar
Unsigned TRUE → Sensor error
Integer FALSE → Sensor OK
Unsigned Value = 40 → Device ID = 40

Bit Write relay status, if it is
released to Modbus control
(→ 7.4 Menú Salida, página 13).
value = 0x0000 → Relay off
value = 0xFF00 → Relay on
