● After successful initialization of the CS31 bus communication, the CS31 bus LED lights up.
The S-ERR LED goes out.
● During operation, the yellow LEDs indicate the signal statuses of the channels.
1.5.2.7 Diagnosis and Displays
LEDs are used for diagnosis and display purposes. In addition, some diagnosis information can
be transmitted via the CS31 bus.

Error description
Device error
Channel error
*) The channel numbers are grouped as follows:
0 - for X2 / 1.0 to 1.7
8 - for X2 / 2.0 to 2.7
15 - for X5 / 3.0 to 3.7 and X6 / 4.0 to 4.7

The S-ERR LED remains on even if the error no longer occurs. The error must be confirmed by
the control system (PLC/central unit), e.g. by means of a function block
data and CS31 bus system data" on page 4.

The error codes that are transferred by the replacement device via the CS31
bus bus are newly displayed in CODESYS. Each error code of the CS31 bus
(table column 3) produces the error code in CODESYS (table column 2). As a
result, it is possible to operate the replacement device with a new control
system (PLC/control unit), e.g. 07KT98-ARC-AD, as well as with an old control
system (PLC/central unit), e.g. 07KT98.
