Activating control elements for manual mode

After an axis was prepared for manual mode by G200/G201, this axis can be assigned a logical control element (button/handwheel) by a parameter set. This takes place during activation of an axis.

The default value settings are defined in the axis-specific parameter lists:

# 1 handwheel, 2 continuous, 3 incremental

handbetrieb.default.operation_mode 2 # 2 continuous,

handbetrieb.default.control_element 1 # logical handwheel/key

The default value used is the 0th parameter set (index = 0) of the manual mode parameters.

Every time the manual mode (see Operation mode types) or G200/G201 is reselected, the last known setting of the axes (operation mode, link to control element and parameter set) is restored.

Activating control elements with manual mode
Description	Control unit to manage data to activate a control element and assign it to an axis in manual mode, including flow control of user data.
Data type	MC_CONTROL_HB_ACTIVATION_UNIT, see description Control Unit mit Verbrauchskontrolle
Special features	This control unit can only be used if the CNC is in manual mode or if the axes are enabled for manual mode by an explicit G200/G201. Otherwise, activation is refused with an error message (e.g. 150048 -> “Impermissible selection of operation mode in continuous jog mode”).
ST path	gpCh[channel_idx]^.hb_mc_control.activation
Access	PLC reads request_r and writes command_w + enable_w
Commanded, requested data
ST element	.command_w .request_r
Data type	HLI_HB_ACTIVATION, for description, see Section User data on activation
Flow control commanded data
ST element	.command_semaphor_rw
Data type	BOOL
Value range	[TRUE, FALSE]
Special features	Consumption data item
Access	CNC accepts the commanded data if this element has the value TRUE and sets this element to the value FALSE after complete acceptance of the data. PLC can write data for commanding if this element has the value FALSE. The PLC sets this element to the value TRUE if all data to be commanded is written.
Flow control of requested data
ST element	.request_semaphor_rw
Data type	BOOL
Value range	[TRUE, FALSE]
Special features	Consumption data item
Access	CNC writes the data requested by the GUI if this element is FALSE and then sets this element to TRUE. PLC reads the data requested by the GUI if this value is TRUE. After the PLC fully accepts the data, the PLC sets this element to FALSE.
