Explicit Message Connection
Device Status is available by reading Class 1, instance 1, attribute 5. Vendor specific interface
for alarms and diagnostic for Explicit Message Connections is defined as follows:
Presence of process alarm can be detected by reading class 29, instance 1, attribute 5 and
class 30, instance 1, attribute 5. The module mode (
Run
or another state) has to be checked,
because the alarm bit is set to 0 = OK every time the module is not in
Run
mode.
The module mode can be detected by reading class 120 Instance 5 Attribute 1.
The presence of module diagnostic events can be detected by reading class 120 Instance 6 At-
tribute 1.
Detailed reasons for process alarms and system diagnostic events can be found out by reading
all 60 attributes of Class 120 Instance 3 which contains the dedicated system status bytes.

Implicit Message Connection
If assembly instance 57 is used, Bit 6 and 7 of Byte 66 signal a process alarm when set.
If assembly instance 167 is used, Bit 6 and 7 of Byte 66 signal a process alarm when set. Bit 5
signals diagnostic events or process alarms when set.
Event details can be queried by Explicit Message requests as described here:

MS (Module Status)
The SP-COP2-ENI module possesses a two-color (red/green) LED with the designation
MS
.
This is the
Module Status Indicator
.
The Module Status Indicator is
dark , if no power supply is connected. It flashes green if the
device has not been configured. It turns green if the device is running correctly. It flashes
green/red
if the device is performing a switch-on test.
The Module Status Indicator
flashes red if EtherNet/IP is activated and the device has detected
a serious, eliminable error. A faulty project file or one which does not match the hardware is
classified as a serious, eliminable error. The display
turns red if EtherNet/IP is activated and the
device has detected a serious, non-eliminable error and there is a
Critical Fault
.
