Channel-specific interface
Version identifier PLC → CNC | |
Description | If the version of the HLI is evaluated at the NC kernel end, the PLC stores the agreed version identifier in this element. Evaluation at the NC kernel end must be agreed for a specific application. |
ST path | gpCh[channel_idx]^.head.version_w.zeichen |
Data type | STRING(HLI_INTF_VERSION_NAME_LAENGE) |
Access | PLC is writing |
Special features | Is currently not evaluated in the NC kernel. |
Version identifier CNC → PLC | |
Description | If the version of the HLI is evaluated at the PLC end, the NC kernel stores the agreed version identifier in this element. Evaluation at the PLC end must be agreed for a specific application. |
ST path | gpCh[channel_idx]^.head.version_r.zeichen |
Data type | STRING(HLI_INTF_VERSION_NAME_LAENGE) |
Access | PLC is reading |
Size of the HLI | |
Description | The NC kernel writes the size of the entire channel-specific interface area in this element. |
ST path | gpCh[channel_idx]^.head.sizeof_interface_r |
Data type | UDINT |
Unit | Byte |
Access | PLC is reading |
PLC present | |
Description | The PLC signals that it is present by setting the value to TRUE.
|
ST path | gpCh[channel_idx]^.head.plc_present_w |
Data type | BOOL |
Value range | [TRUE = PLC present, FALSE] |
Access | PLC is writing |
Notice
Only if this value is set to TRUE can the PLC influence the NC kernel by channel-specific control units and be supplied with technology commands by the NC kernel.
Channel number | |
Description | Number of the channel that is assigned to this interface on the HLI. |
ST path | gpCh[channel_idx]^.head.channel_nr |
Data type | DINT |
Value range | [1, gNrCh] |
Access | PLC is reading |
Channel name | |
Description | Displays the value of the channel parameter P-CHAN-00174 (channel_name) if the value is stored in the channel parameter list and was assigned a value. |
ST path | gpCh[channel_idx]^.head.channel_name_r.zeichen |
Data type | STRING(HLI_CHANNEL_NAME_LAENGE) |
Access | PLC is reading |
Special features | If the value of the parameter P-CHAN-00174 (channel_name) is changed in the channel parameter list, the change in this element is only visible when a command is output to re-interpret the channel parameter list. |
channel type | |
Description | Displays the value of the channel parameter P-CHAN-00175 (channel_type) if the value is stored in the channel parameter list and was assigned a value. Otherwise, 0 is displayed. |
ST path | gpCh[channel_idx]^.head.channel_type |
Data type | DINT |
Value range | [DINT_MIN, DINT_MAX] |
Access | PLC is reading |
Special features | Available as of CNC Build V3.1.3118 If the value of the parameter P-CHAN-00175 (channel_type) is changed in the channel parameter list, the change in this element is only visible when a command is output to re-interpret the channel parameter list. |
NC kernel start-up completed | |
Description | By setting this value to TRUE, the NC kernel signals to the PLC that the NC kernel start-up is completed and that the HLI is now supplied cyclically. This means that the display data is valid and the control commands are transferred to the NC kernel. |
ST path | gpCh[channel_idx]^.head.hochlauf_quit_r |
Data type | BOOL |
Value range | [TRUE = start-up of NC kernel completed, FALSE] |
Access | PLC is reading |
Data of channel list parameter P-CHAN-00280 | |
Description | The data configured by the user in the channel list in the parameter P-CHAN-00280 is provided here on the HLI. |
Signal flow | CNC -> PLC |
ST path | gpCh[channel_idx]^.head.customer_val_r[ ] |
Data type | ARRAY [0..HLI_CHANNEL_CUSTOM_MAXIDX] OF UDINT |
Access | PLC is reading |
Enable: Update the HLI | |
Description | By setting this value to TRUE, the PLC can enable the function to update the entire channel-specific interface area. |
ST path | gpCh[channel_idx]^.head.update_request_enable_w |
Data type | BOOL |
Value range | [TRUE = update the HLI enabled, FALSE] |
Access | PLC is writing |
Special features | Currently not supported, i.e. the HLI is updated in every NC cycle. |
Update the HLI | |
Description | By setting this value to TRUE, the PLC can initiate an update of the entire channel-specific interface area. This value is reset to FALSE by the NC kernel after the update is completed. |
ST path | gpCh[channel_idx]^.head.f_update_request_rw |
Data type | BOOL |
Value range | [TRUE = update the HLI activated, FALSE] |
Access | Read/write |
Special features | Currently not supported, i.e. the HLI is updated in every NC cycle. |
Update cycle of the HLI | |
Description | Using this element, the PLC informs the NC kernel of the number of interrupt cycles the NC kernel may distribute the updating of the axis-specific interface area. This leads to a reduced load on the interrupt task in particular with multi-channel and multi-axis configurations. |
ST path | gpCh[channel_idx]^.head.n_update_tick_count_rw |
Data type | UINT |
Unit | Number of interpolator cycles |
Access | PLC is writing |
Special features | Currently not supported, i.e. the HLI is updated in every NC cycle. |
