12.34 210Dh – Valve status if communication is lost
In the event that the communication is lost (PLC  LEMCOM master module or LEMCOM master
module  LEMCOM secondary modules), the behavior of the suction and blowing valves can be
defined.
The following modes are possible:
MODE
Byte 0
Detailed operation
MD1
00h

The subindex is used to define the module to be set (from 1 to 16):
- Subindex = 0x01  set VALVE_STATUS on master module (address #0)
- Subindex = 0x02  set VALVE_STATUS on secondary module at address #1
- …
- Subindex = 0x10  set VALVE_STATUS on secondary module at address #15
Byte 0 is used to define the operating mode of the valves according to the above table. Mode MD1
is the default operating mode.
