Error message
Cause(s)
Remedy
R08
No PLC program loaded
(for gateway: reserved)
The attempt was made to start a PLC program
although no program had been loaded to the
controllerE.
►
Load PLC program to the controllerE:

RS-232 recognition baud rate
(for gateway: reserved)
The hardware of the integrated serial interface
chip has found a transfer error in the RS-232 data
flow.
Possible causes:
1.
Baud rate setting in the device different from
the setting in the PC.
►
Adapt
baud
rate
R09
2.
Other programs (e.g. messenger) send via
the RS-232 interface of the PC.
►
Exit other programs on the PC.
RS-232 buffer overflow
A buffer overflow was found in the serial receive
buffer of the RS-232 interface.
Possible causes:
1.
RS-232 telegram too long or baud rate too
high.
►
Check driver or reduce baud rate.
R10
2.
Faulty connection cable between PC and
RS-232 connection on the device.
►
Replace connection cable.
R11
RS-232 parity check
The parity check of the serial data flow of the RS-
232 interface was unsuccessful.
Possible cause:
Electromagnetic interference.
►
Reduce interference on the RS-232 cable
by means of the following measures:
- Screen cable,
- Reduce cable length,
- Remove interfering source.
R12
ASC0 handler switched
The decoding of the serial data flow was changed.
Possible cause:
Command for switching the device to the test
mode / normal operating mode during serial data
flow.
►
Remove error in the protocol driver.
R13
24 V voltage unstable
During normal operation voltage drops below 1 V
were found on the 24 V power supply cable.
►
Permanently stabilise 24 V supply voltage
above 20 V.
Better:
►
Use a switched-mode power supply to
supply the device with power.
R14
24 V voltage error restart
The voltage failure of the 24 V power supply
caused the device to start again.
►
Acknowledge
message.
►
The device resumes the normal operating
mode.
►
In future: Use a switched-mode power
supply to supply the device with power.
