Figure 6-1 Traversing axes displayed
Acknowledging display/skipping by HMI on PLC
The HMI communicates to the PLC whether the traversing keys are displayed or hidden. This
is done using bit 7 in byte 72 of DB 10:
Displayed: DB10.DBX72.7 = 1
Skipped: DB10.DBX72.7 = 0
User keys
The user keys (the 2 keys at the top and bottom) can be assigned in any way. User keys, which
can be used to trigger a wide range of machine functions, are evaluated directly by the PLC
program.
