101
INPUT
3
Gripping status (2 bytes)
Heartbeat (1 byte)
Used to get “Object gripped” information of all the modules of a LEMCOM island. Each bit of
the 2 bytes word corresponds to a module. Bit = ‘1’ means that the product handled by the
corresponding LEMCOM module is gripped (vacuum level is above L1 threshold).
This input instance also includes a Heartbeat byte. This helps users to monitor Ethernet
communication status between PLC and LEMCOM.
102
INPUT
19
Gripping status (2 bytes)
Heartbeat (1 byte)
Vacuum level (16 bytes)
Contains same data as instance 101 and the Vacuum level values of all the modules of the
island (Master module and secondary modules at address 1 to 15). Vacuum level is given in
percent vacuum (0 to 99%).
140
INPUT
34
Heartbeat (1 byte)
Unused (1 byte)
Island composition (2 bytes)
Gripped information (2 bytes)
Regulation information (2 bytes)
Vacuum level
– % vacuum (16 bytes)
Lost part alarm (2 bytes)
Regulation error alarm (2 bytes)
30MCycles alarm (2 bytes)
Temperature alarm (2 bytes)
Power supply alarm (2 bytes)
Input assembly 140 gives some more diagnostic data of the LEMCOM island such as:
-
A list of the connected modules (island composition)
-
Alarm signals for regulation, lost part, power supply, etc.
All diagnostic data are coded in a 2 bytes word where each bit corresponds to the 1 to 16
LEMCOM modules that may be on the island (1 master and up to 15 secondaries).
141
INPUT
78
Heartbeat (1 byte)
Selected module in instance 111 (1 byte)
Island composition (2 bytes)
Gripped information (2 bytes)
Regulation information (2 bytes)
Vacuum level
– % vacuum (16 bytes)
Lost part alarm (2 bytes)
Regulation error alarm (2 bytes)
30MCycles alarm (2 bytes)
Temperature alarm (2 bytes)
Power supply alarm (2 bytes)
Counter - external vacuum cmd (4 bytes)
Counter - internal vacuum cmd (4 bytes)
Counter - blow off cmd (4 bytes)
Counter - Handled parts (4 bytes)
Counter - Lost parts (4 bytes)
Counter - ASC regulation(4 bytes)
Counter - Regulation errors (4 bytes)
Counter - Local bus com error (4 bytes)
Counter - Field bus com error (4 bytes)
Counter
– Power supply error (4 bytes)
Power supply (2 bytes)
Temperature (2 bytes)
Contains same data as instance 140 + the complete diagnostic data related to the module
selected in the last byte of instance 111.
