Diagnosis / behavior in case of an error
The MTQ22-FBP.0 provides detailed diagnosis information about the status of the connected devices, its own status and the
status of the Modbus TCP connection.
Diagnosis information is accessible
• with the locally available lamps and
• via the Modbus TCP services.
The possibilities of locally available diagnostics are described in the next section.
LED status indications
Diagnosis information is locally displayed using two light emitting diodes (LEDs) per interface to an FBP device. The meaning
of the LEDs is as follows:
LED
Port 1,2,3,4
Explanation
Off
Disabled (no device configured)
Green blinking
Startup (waiting for device)
Green on
Configured device identified and data exchange
running
Red blinking
Communication fault
Green / Red alternating
Address mismatch between expected device address
and connected device address.
E.g. caused by swapping two devices.
Wrong device type connected.
*) Only for intelligent devices like UMC or PST. Not for passive sensors.

MTQ22-FBP.0 Status
LED RDY
General Status
Explanation
Green on
Normal
Red blinking
Minor error, e.g. wrong configuration or
IP address already available in the network.
Red on
Major internal fault. If the error is permanent after
reboot, the device must be replaced.
LED TCP
Communication Status
Explanation
Green blinking
Waiting for Modbus TCP connection
Green on
At least one Modbus TCP connection established
Red blinking
One or more (as parameterized) connections timed out
Red on
Fatal error
Green / Red alternating
Error in the TCP/IP configuration

Ethernet Status
The Ethernet status is shown at the two LEDs integrated in the RJ45 connectors.
Off
On
Flashing
Data LED Yellow
No network traffic

Communication with network
active

Link LED Green
No connection to network, e.g.
because a cable is not plugged in
or a wire is broken.
Connection to network
established (e.g. connection with
network switch)
