The handheld programming unit (HPU) is especially suitable for handling tasks.
It is connected to the SINUMERIK 840D via the MPI or OPI interface and can
be used either instead of or in addition to an MMC/MCP.
The HPU includes the operating functions of the MCP.
The state of the operator elements (button pressed/released) is entered in an
8-byte data block and transferred cyclically by global data service to the PLC.
The operator elements are evaluated by the PLC.
The following MCP functions can be executed on an HPU with a standard as-
signment:
S
Start and stop programs
S
Change operating mode
S
Manually traverse 5 axes in both directions
S
Change override
S
Switch programs to Reset
S
Switch over WCS/MCS for travel commands
S
Activate single block
S
Select increments (INC1, INC10, ...)
The following MCP functions are not provided by the HPU and are assigned
permanent values:
S
Spindle speed override
S
Spindle start/stop
S
Keyswitch
S
Feedrate start/stop
The software version of the HPU appears in the display after power up until
communication between the PLC and the HPU has been established.
