Keystroke Simulation; Itnc Control Panel - HEIDENHAIN iTNC 530 HSCI Technical Manual

8.4 Keystroke simulation

8.4.1 iTNC control panel

1392
HEIDENHAIN contouring controls have two control panels:
iTNC control panel

The machine operating panel from the machine tool builder

The control and operating panels are attached to the MC 6xxx via USB
interfaces.
The key code of the iTNC keyboard unit is evaluated directly by the NC.
The machine operating panel has its own PLC inputs and outputs. These are
transmitted via HSCI. You must configure the inputs and outputs using
IOconfig, and evaluate them in the PLC.
The key code of the iTNC keyboard unit is evaluated by the NC. The key code
is displayed in W274 while a key is being pressed. (see "Codes for keystroke
simulation" on page 1400).
If you press a disabled key, marker M4577 is also set.
The following modules can influence keys and soft keys:
Module 9180: Simulate NC keys

Module 9181: Disable individual NC keys

Module 9182: Re-enable individual NC keys

Module 9183: Disable groups of NC keys

Module 9184: Re-enable groups of NC keys

Module 9186: Call a soft-key function

Module 9187: Status of a soft-key function call

Module 9188: Call a soft-key function

With MP4020 bit 9, specify whether a simulated key should only be
transmitted to the NC, or also to an active PLC window.
With MP4020 bit 10, specify whether a disabled key should be disabled only
for the active PLC window, or for the active PLC window and for the NC.

MP4020 PLC compatibility
Input: Bit 9 – Behavior of a simulated key
0: Simulated key is transferred immediately to the NC
1: Simulated key is processed first by an active PLC window
before being transferred to the NC
Bit 10 – Behavior of a disabled key
0: Locked key only works on the active PLC window
1: Locked key works on neither the active PLC window nor on
the NC
