Diagnostics and troubleshooting

8.9.1

Notifications via network

8.9.1.1 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, in-
stance 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 Attribute 1.
Detailed reasons for process alarms and system diagnostic events can be found out by reading all 60 at-
tributes of Class 120 Instance 3 which contains the dedicated system status bytes.
8.9.1.2 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 dia-
gnostic events or process alarms when set.
Event details can be queried by Explicit Message requests as described here: Explicit Messaging [chapter

LED States

8.9.2.1 MS (Module Status)
The MSI 430 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 per-
forming 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.
