Transient status conditions (continued)Table 10-5:
LED Color Status Priority Comments
Solid Green OK 4 Normal operation.
10.3.4 System Status LED
The System Status LED indicates the status of the overall system. It indicates the active
status condition with the highest priority of all boards in the system. For example, if the
Test Function generator on the A6560R Processor card is uncalibrated and the first MSIG
module has a power fault, the LED will show a solid red color to indicate the MSIG module
power fault, which is a “Failure” state.
When all the firmware components are operating as expected, this LED overlays a
"heartbeat" pattern on top of the system status. The pattern occurs in a four-count cycle.
The LED is pulsed off for the first and second counts, and then on for the third and fourth
counts. In practice, it gives the appearance of a human heartbeat. If the pulse pattern
stops, it indicates a firmware fault has occurred. Many times the system is capable of
recovering. However, if the system cannot recover quickly, it will automatically reboot
itself to clear the fault and will then resume monitoring.
10.3.5 Server Connect LED
The Server Connect LED indicates when AMS Machinery Manager software or the DHM
diagnostic software are connected.
• A green color indicates that at least one AMS Machinery Manager software client is
connected or that the DHM software is connected in the client mode.
• A red color indicates the DHM software is connected in the Single User mode. In this
state, no other clients can connect.
• If the LED is off, it indicates that neither of these types of software clients are
connected.
There is no indication of client data transfer, only the presence of at least one established
connection.
10.3.6 Modbus Connect LED
The Modbus Connect LED indicates when a Modbus client, Web Browser, or Transient Live
client are connected.
• A green color indicates that at least one of these types of clients has established a
connection.
• If the LED is off, it indicates that none of these types of clients is connected.
The red color is not used with this LED.
There is no indication of client data transfer, only the presence of at least one established
connection.
