Beschreibung
Zusammenfassung:	The present invention provides methods, systems and computer program products for detecting a configuration error or operating error corresponding to an input/output (I/O) device. The I/O device comprises a plurality of I/O points configured to establish a combined I/O channel between said I/O device and a field device, said combined I/O channel comprising a primary I/O channel and at least one secondary I/O channel. A validation device requests the I/O device to send signal patterns on the primary and secondary channels and then records the transmitted signals to compare them to predefined signal pattern stored in a repository, in order to detect an error either in configuration or operation.
