Cam controller diagnostics

Diagnostic displays in the online dialog

The upper part of the dialog box shows the current position of the cam encoder in degrees and the current encoder velocity in [rpm]. Several 32-bit binary values are shown below, which can be interpreted as follows. For a single output group with 32 tracks each bit corresponds to a digital output. The bit with the lowest value on the right is assigned to output 0, the bit with the highest value is assigned to output 31. If more than one output group was configured, the group number can be set via the Output Group (Outp. Grp.) dialog box. Groups of 32 outputs can therefore be considered separately. The displayed data have the following meaning:

Cam Tab. Val: Current cam table row corresponding to the displayed angle.

Counter AND: Cams can be activated during each revolution or only during each n-th revolution. The counter mask indicates that an output can become active at the displayed angle.

PLC OR: Current OR mask determined by the PLC (PlcOrMask).

PLC AND: Current AND mask determined by the PLC certain (PlcAndMask).

Cam Output: Currently issued dataset for 32 output tracks. The output is generated through linking of the cam table with the described masks.

Cam Table: Complete cam table with one row for each of 32 outputs for each resolved angle position (second column on the right next to the 32-bit value). The table has 360 entries, depending on the parameterised resolution, or it contains the number of rows that matches the encoder resolution (e.g. 4096). The cam table contains the raw data calculated from all cams for the cam track output. The calculation is based on the set velocity HPM Preset.
