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.
An exceedance of the measuring range is signaled even if nothing is connected
to an analog voltage input.
