Object 2108h is used to activate/deactivate the time-delayed automatic blowing function on each of
the modules on a LEMCOM island.
If the option is activated, the LEMCOM module automatically triggers blowing as soon as the
vacuum command is deactivated (the blowing duration is defined in object
2109h ).
The SDO command related to the Automatic Blowing option is the following:
Client (master)

The Automatic Blowing option of each module (1 = active / 0 = inactive) is defined by the 16 bits of
bytes

The
subindex is used to define the module to be set (from 1 to 16):
- Subindex = 0x01

set AUTO_BLOW_DURATION on master module (address #0)
- Subindex = 0x02

set AUTO_BLOW_DURATION on secondary module at address #1
-
…
- Subindex = 0x10

set AUTO_BLOW_DURATION on secondary module at address #15
Byte 1 - Byte 0 are used to define the value of AUTO_BLOW_DURATION.
AUTOMATIC BLOWING DURATION
The automatic blowing duration must range from 100 to 9999 ms (64h to 270Fh).
Default value: AUTO_BLOW_DURATION = 500 ms.
