4.4.8 EZE-2 Event Logger
EZE-2 event logger can store the data about events and failures in records with
the date and time. EZE-2 is connected to the CANBUS transmission link between
PLC A and PLC B. Event logging is possible independently on the status of the
transmission to the remote control device. Time used by EZE-2 is synchronised
with the time used by ERP-7.

EZE-2 event logger uses FLASH memory with capacity for at least 65000 events
or failures to be logged in the buffer. 8 LED indicators inform about EZE-2
performance. Meaning of LEDs is as follows:
D1 (green)
-
power supply,
D2 (yellow)
-
not used
D3 (yellow)
-
not used
D4 (yellow)
-
CAN transmission from PLC to EZE-2 (Z2 connection),
D5 (yellow)
-
CAN transmission from EZE-2 to PLC (Z2 connection),
D6 (yellow)
-
RS232 transmission from PC to EZE-2 (Z3 connection),
D7 (yellow)
-
RS232 transmission from EZE-2 to PC (Z3 connection),
D8 (red)
-
fault.
If D1 is on constantly and D8 is off then EZE-2 works properly. During normal
operation of EZE-2 D5 should flash (100ms for every few seconds) – that means
that EZE-2 communicates with PLCs.
