(3) HMI file HT8_xx.INI
The language-dependent inscription of the traversing keys can be defined in the HMI file
HT8_xx.INI in the [Axiskey text] character strings section
(4) Mapping of keys
The mapping of keys in the NC/PLC interface is shown by the following table:
Keyboard layout
NC/PLC interface signal
SF1, SF2
EB n + 6, Bit 4, Bit 5
SF3, SF4
EB n + 6, Bit 2, Bit 3
Ax<n> + / -
EB n + 3 / n + 4, Bit 0 - Bit 5
Note
Keys SF1 - SF4
The SF1 to SF4 softkeys are not assigned. The functionality must be implemented by the
user (machine manufacturer) in the PLC user program. The keys cannot be inscribed.
(5) Switching traversing key signals and axes
Traversing key signals
The traversing key signals are transferred by the FC 26 functions in the active MCS
coordinate system to the traversing key signals of the machine axes recorded in DB 10,
DBB 8 - 13 (1st MCP) or DB 10 DDB 32 - 37 (2nd MCP).
NC/PLC interface signal
Signal designation
Machine axis from:
EB n + 2 / n + 3, Bit 0
Ax1 + / -
DB 10, DBB 8
EB n + 2 / n + 3, Bit 1
Ax2 + / -
DB 10, DBB 9
etc.
The FC 26 function transfers the traversing key signals Ax1 to Ax3 +/- to the traversing key
signals of the geometry axes of the specified channel in the active WCS coordinate system
(FC 26 parameter: "ChanNo"). See also Chapter Activate traversing keys (Page 212)
Switch over axes
The axis switchover request can be used to write e.g. the next 6 machine axes in the table in
DB 10, DBB 8 - 13 (1st MCP) or DB 10 DDB 32 - 37 (2nd MCP) in the PLC user program.
(6) Dispay traversing keys
The display of the traversing key inscription can be requested with the output signal in the
PLC user program.
