Error description RTS errors: error codes R01...R46
257
Error message Cause(s) Remedy
R08 No PLC program loaded
The attempt was made to start a PLC
program although no program had been
loaded to the controllere.
► Load PLC program to the
controllere:

124 , chapter Connect the
programming device
R09 RS-232 frame error (Baudrate)
The hardware of the integrated serial
interface chip found a transmission error
in the RS-232C data flow.
Possible causes:
1. Baud rate setting in the controllere
is different from the setting in the
PC.
► Adapt baud rate:
→ page
121 , chapter Set the baud rate
of the serial interface
2 Other programs (e.g. Messenger)
are using the RS-232-interface of
the PC
► Exit other programs on the PC.
R10 RS-232 buffer overflow
A buffer overflow was found in the serial
receive buffer of the RS-232C interface.
Possible causes:
1. RS-232 telegram too long or baud
rate too high
► Check driver or reduce baud rate.
2. Faulty connection cable between
PC and RS-232C connection on the
controllere
► Replace connection cable.
R11 RS-232 parity check
The parity check of the serial data flow
of the RS-232C interface failed.
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: during the serial data
flow, command to change to the test
mode / normal operating mode of the
device.
► Remove error in the protocol driver.
R13 24V power unstable
During normal operation voltage drops
below 18 V were found on the 24 V
power supply cable.
► Stabilise the 24 V supply voltage
so that it is permanently above
20 V.
Better:
► Use of the switched-mode power
supply.
