| Citect does not generate any Hardware
errors. Citect displays hardware errors to tell you that it has
found a problem with your system. They are really system messages
caused by things outside of Citect's control. For example, when
Citect displays a hardware error on a PLC, Citect is just reporting
the error the PLC is returning. Citect is not generating a error,
the error is coming from the PLC - you need the error to find out
what is the real problem.
Hardware errors are also reported when Citect finds a problem
with your project configuration. For example, calling a Cicode
function with an incorrect argument. The major causes of hardware
errors are as follows:
| Source
|
Cause
|
| PLC errors
|
The PLC has an error
that Citect is reporting, or Citect is unable to communicate to the
PLC. Communication problems are usually caused by faulty hardware ,
cables or incorrect protocol setup.
|
| Device errors
|
External devices, for
example printers, databases and files can cause many hardware
errors because they are external to Citect, ie outside of total
control of Citect. The device may not exist, the directory may not
exist, the device may be full, jammed, or switched off.
|
| Cicode errors
|
Cicode errors are
generated when your project configuration calls a Cicode function
in a invalid way. This is Citect telling you, to check your project
configuration. Note that the extra hardware alarms fields ERRPAGE
and ERRDESC can help you locate the error.
