Error handling
10.1
General
The
HEINZMANN
control units have an integral error monitor with which errors in
setpoints, sensors etc. can be detected and displayed.
There is a permanently assigned digital error output to which the general error message is
applied.
10.2
Error types
The following basic error types can be identified:
Errors in configuring and parameterizing the control unit
These errors as caused by incorrect inputs made by the user and which the PC or
hand programmer cannot intercept. They do not occur with a standard production
control unit.
Errors during ongoing operation
These errors are the most important errors in a control unit in serial operation. This
category includes sensor errors such as the failure of the setpoint generator.
Internal computing errors of the control unit
These errors can be due to faulty components or other unacceptable operating
conditions. They do not occur in normal circumstances.
The different errors can be taken from parameter numbers 3000..3099. When an error is
currently present the value is set to 1, otherwise it is 0.
When rectifying an error, the cause should be eliminated first and then the current errors
should be cleared (reset). Some errors also reset by themselves as soon as the cause has
been removed. Errors can be reset with a PC, a hand programmer or, given the appropriate
configuration, with the switch function 2828
SwitchErrorReset
. If the error is still present,
you will need to continue looking for the cause.
The control unit always starts with the assumption that no error is present and then checks
the error conditions. The control unit can therefore be put in an error-free condition by a
, however currently present errors are immediately displayed
again.
