9.4 HNC100 error messages - error handling
In the case of an error, the output “ready” (OUT 4) of the HNC100 changes to 0 V,
thus signaling to the higher-level control that an error has occurred. To be able to
analyze the error in more detail, an error code can be read out from the HNC100
over Profibus.
The error can be cleared by withdrawing the enable IN 1.
