4.1.1 General notes
This section describes the special program functions of the PC Worx software that are
available for the Inline controller.
The Inline controller has a register set, which is used for diagnostics and easy control of the
bus system. The diagnostic data is stored in the diagnostic status register and the
diagnostic parameter register. These registers are available to the application program as
system variables (system flags, global variables).
Operating states, error states, and additional information about the INTERBUS system can
be evaluated in the application program.
For additional information on diagnostics, please refer to the following user manual:
INTERBUS Diagnostics Guide (IBS SYS DIAG DSC UM E), Order No. 2747293
Not all system variables that are listed in this user manual are available in firmware
versions < 3.95. At least firmware Version 3.95 is required in order to use all system
variables.
