100
OUTPUT
4
Vacuum control (2 bytes)
Blow-off control (2 bytes)
Used to send vacuum and blow-off commands to all the modules of a LEMCOM island, i.e. to the master module
and to the 1 to 15 Secondary modules that may be connected to the master. Vacuum and blow-off are independent
which means that vacuum can be activated at the same time as blow-off (might be useful for high speed
application).
110
OUTPUT
6
Vacuum control (2 bytes)
Blow-off control (2 bytes)
Island restart (1 byte)
Unused (1 byte)
Same as above + global restart of the island (first bit of the 5
th
byte).
111
OUTPUT
6
Vacuum control (2 bytes)
Blow-off control (2 bytes)
Island restart (1 byte)
Module selection for diagnostic (1 byte)
To be used concurrently with Input instance n° 141.
Same as above + one byte used to define the module for which the diagnostic data have to be sent back in input
instance 141. By default, master module (0) is selected.
112
OUTPUT
74
Vacuum control (2 bytes)
Blow-off control (2 bytes)
Island restart (1 byte)
Settings modification allowed (1 byte)
L1 threshold (16 bytes)
h1 threshold (16 bytes)
L2 threshold (16 bytes)
h2 threshold (16 bytes)
ASC option (2 bytes)
DIAG_ECO option (2 bytes)
Same as instance 110 + the ability to adjust vacuum settings (gripping and regulation thresholds, regulation
system) during the process. This can be useful for applications that require different settings from one cycle to
another.
Settings are applied to the LEMCOM modules only when the first bit of the “Settings modification allowed” byte is
set to ‘1’.
WARNING:
never maintain
“Settings modification allowed” bit to ‘1’ all the time, this would constantly
update all LEMCOM units parameters and overwhelm master module (communication loss or
vacuum/blow-off commands hazards).
LEMCOM settings modification must be done carefully while machine is not running.
