Entering data in log
files
The error log file can be used by the PLC for diagnostic purposes.
Entering data from the PLC into the error log file:
Use Module 9275 to write ASCII data into the error log file
Use Module 9276 to write the contents of operands into the error log file
Module 9275 Write ASCII data into the log
The module writes a character string from a PLC string or an immediate string
into the error log file. The entry can be given a special identifier for fast finding
or later editing.
A buffer of approx. 210 bytes is available for the data to be written (including
the entry identification).
Call:
PS B/W/D/K/S<Log entry>

CM 9275
Error recognition:
Do not use Modules 9275 and 9276 in the PLC program as shipped.
Instead, use them only for debugging. Otherwise the processing times
could be increased and the hard disk could be written to unnecessarily.
