9.2.1
Troubleshooting for MODBUS
• Are the device and the master using the same baud rate and parity?
• Is the wiring of the interface OK?
• Does the device address sent by the master match the configured device address of the transmit-
ter?
• Do all slaves on the MODBUS have different device addresses?
9.2.2
Device error/alarm relay
There is a global "alarm relay" (the user can either assign the relay or one of the open collectors in
the setup).
This "alarm relay" switches if errors or type "F" (Failure) occur, i.e.:
Errors of type "M" (Maintenance required) do not switch the alarm relay.
For errors of type F, the color of the backlighting of the display also switches from white to red.
9.3
Diagnosis list
The device has a diagnostic list in which the last 10 diagnostic messages (messages with error num-
bers from type Fxxx or Mxxx) are stored.
The diagnosis list is designed as a ring memory, i.e. if the memory is full, the oldest messages are
overwritten automatically (without message).
The following information is stored:
• Date/time
• Error number
• Fault Text
The diagnosis list is not read out via PC operating software. However, it can be displayed via Field-
Care.
The following fall under Fxxx or Mxxx:
• Open circuit
• Sensor error
F501
Invalid configuration
Check setup
M502
Device is locked!
- e.g. for firmware update attempt
Check the hardware switch on the device
F900
Input variable(s) outside the calculation limits (see Technical data,
• Check plausibility of the measured input values
• Check scaling of device inputs/sensor outputs
• Check system/process
M908
Analog/pulse output error
Check process values and scaling of the output, select larger full
scale value (or pulse value) if necessary.
F910
Firmware for this device not released.
Install correct firmware.
M918
Preset counter may not be 0!
Enter value for preset counter.
M919
Flow rate greater than low flow cut off!
Check sensors, valves or pumps.
M920
Batch aborted. No flow!
Check sensors, valves or pumps.
M921
Fill deviation exceeded!
M922
Fill deviation undershot!
