4.2 Function configuration of the inputs and
outputs
For some devices of the ecomat mobile controller family, additional diagnostic functions can be
activated for the inputs and outputs. So, the corresponding input and output signal can be monitored
and the application program can react in case of a fault.
Depending on the input and output, certain marginal conditions must be taken into account when
using the diagnosis:
•
It must be checked by means of the data sheet if the device used has the described input and
output groups.
•
Constants are predefined (e.g. IN_DIGITAL_H) in the device libraries (e.g.
ifm_CR0020_Vx.LIB
) for the configuration of the inputs and outputs. For details

4.2.1 Configure inputs
Digital inputs
Depending on the controller, the digital inputs can be configured differently. In addition to the
protective mechanisms against interference, the digital inputs are internally evaluated via an analogue
stage. This enables diagnosis of the input signals. But in the application software the switching signal
is directly available as bit information. For some of these inputs the potential can be selected.
