4.5 Diagnostics
To read the diagnostics data, use Modbus function code 3 Read Holding Registers or 4 Read
Input Registers. The following chapter presents register values associated to diagnostic data for both PSE
and MTQ-FBP devices.
4.5.1 MTQ22-FBP
The status of the connected FBP devices can be read via Modbus TCP on the addresses 0x80 to 0x83 for the
devices connected to port 1 ... port 4.
Address
FBP communication status
80h
Port 1
81h
Port 2
82h
Port 3
83h
Port 4
The communication status is zero (0) in case of no error. A value different from zero indicates an error. The
value itself describes the error reason.

1
Wait for FBP device.
Communication not yet
established.
 Check that the FBP device is powered.
 Check the wiring between the FBP device and
the MTQ22-FBP.
2
Unsupported FBP Device. An
unsupported device was
connected to the MTQ22-FBP.
 Check that a PSE is connected and not another
device.
3
Communication Fault on Module
Port. Communication to a FBP
device was established but was
lost again.
 Check the FBP device.
 Check that the FBP device is powered.
 Check that the drawer is inserted (in a
withdrawable system)
4
Address mismatch. The
configured device address and the
real PSE device address do not
match.
 Fix parameterization
 Check that the connected PSE was not
interchanged (e.g. wrong drawer inserted).
5 - 10
General configuration error
 Double-check the configuration
 Check that no unsupported device was
connected.
 Check configuration data sent to the MTQ22-
FBP (if own config was sent)

4.5.2 PSE Softstarter
PSE softstarter diagnostics are represented by bits in a 16-unsigned integer register. Use a calculator to translate
the decimal number to one or more bits. If a bit is set that fault is active and could potentially be resetted.
