Data of a channel-specific technology control unit

Data of a technology function, channel
Description	A technology control unit contains elements for commanding, acknowledging and transferring any required parameters.
Data type	TECHNO_UNIT_CH
ST path	Default synchronisation: gpCh[channel_idx]^.techno_unit_std_sync[tech_unit_idx] Cross-block synchronisation: gpCh[channel_idx]^.techno_unit_late_sync[tech_unit_idx]
Job
ST element	.please_rw
Description	By setting please_rw, the CNC signals to the PLC that the technology control unit is to be executed.
Data type	BOOL
Value range	[TRUE, FALSE]
Special features	Consumption data item
Access	The CNC refreshes the data of the technology function only if this element is FALSE. After updating, the CNC sets this element to TRUE and so element done_w is set to FALSE. The PLC reads the data of the technology function if this element has the value TRUE. After the data is transferred, the PLC sets the value to FALSE.
Function type
ST element	.fkt_ctrl_r
Description	The type of technology function is transferred in fkt_ctrl_r.
Data type	UINT
Value range	Value	Constant	Function
	1	HLI_INTF_M_FKT	M function
	2	HLI_INTF_H_FKT	H function
	3	HLI_INTF_SPINDEL	S function
	4	HLI_INTF_TOOL	T function
Access	PLC reads

Parameter
ST element	.attribut_r.data
Description	Depending on the content of the element fkt_ctrl_r this element contains the parameters of an M function/H function if the technology function type is HLI_INTF_M_FKT or HLI_INTF_H_FKT S function (spindle) if the technology function type is HLI_INTF_SPINDEL T function if the technology function type is HLI_INTF_TOOL
Data type	ARRAY [0.. HLI_TECH_UNIT_CH_MAXIDX] OF BYTE
Access	PLC reads
Acknowledgement
ST element	.done_w
Description	By setting element done_w to TRUE, the PLC signals to the CNC that the technology information was executed.
Data type	BOOL
Value range	[TRUE, FALSE]
Special features	Consumption data item
Access	PLC sets the value to TRUE when the technology function was executed. The CNC sets the value to a FALSE before a new command.
