Incorrect service
code in the
parameter channel
Incorrect code was specified in the management byte or reserved byte during parameter
setting via the parameter channel. The following table shows the return code for this
special case.
Troubleshooting:
Check bits 0 and 1 in the parameter channel.
Incorrect length
specification in
parameter channel
A data length other than 4 data bytes was specified in a
read
or
write
service during
parameter setting via the parameter channel. The following table displays the return
codes.
Troubleshooting:
Check bit 4 and bit 5 for the data length in management byte 0 of the parameter channel.
Both bits must be set to "1".
Internal
communication
error
The return code listed in the following table is sent back if an internal communication
error has occurred. The parameter service transferred via the fieldbus may not have
been performed and should be repeated. If this error persists, switch the MOVI-PLC
®
basic
DHP11B.. controller off and on again. In this way, the control card is reinitialized.
Troubleshooting:
Repeat the
read
or
write
service. If the error occurs again, briefly disconnect the MOVI-
PLC
®
basic
DHP11B.. controller from the power supply and switch the system on again.
If the error persists, consult the SEW Electronics Service.
