6.2.1 Configuring the traversing keys of the HT 8
Prerequisite
In order to display or skip the labeling of the traversing keys, the HT 8 must have user
authorization.
Parameterizing the MCP signals of the HT 8 in the PLC
HT 8-relevant blocks in the PLC program are FB 1 for HT 8/PLC communication and FC 26
for NCK/PLC communication.
Display/skip the labeling of traversing keys on HT 8
In order to inscribe the traversing keys, the names of the first six axes are established from
the machine data 10000: AXCONF_MACHAX_NAME_TAB (indexed using DB 10, bytes 8 to
13).
The LED image of HT 8 serves as the interface for displaying the labeling by the PLC. The
PLC sets a bit in the LED image of the HT 8 to display or skip the traversing keys:
Signal AB n+6 bit 7 = 1 for displaying
Signal AB n+6 bit 7 = 0 for skipping
Note
To ensure that the labeling of the traversing keys is displayed correctly, the names of the axes
must not exceed 10 characters.
Example with labeling of traversing axes displayed:
