Requested and commanded user data

Initial operation mode
Description	Operation mode from which the operation mode is to be changed.
ST path	Commanded value gpCh[channel_idx]^.channel_mc_control.mode_and_state.command_w Requested value gpCh[channel_idx]^.channel_mc_control.mode_and_state.request_r
Commanded, requested value
ST element	.from_mode
Data type	UDINT
Value range	Value	Constant
	1	HLI_IMCM_STANDBY_MODE
	2	HLI_IMCM_AUTOMATIC_MODE
	3	HLI_IMCM_MDI_MODE
	4	HLI_IMCM_MANUAL_MODE
	5	HLI_IMCM_REFERENCE_MODE
Special features	This element does not need to be programmed when the operation mode is changed. However, if a value is specified, a check is conducted when the operation mode is changed to establish whether the CNC is actually in the specified operation mode. A warning is issued if this is not the case.

Initial state of operation mode when the operation mode is changed
Description	State within the operation mode from which the state switchover is to occur.
ST path	Commanded value gpCh[channel_idx]^.channel_mc_control.mode_and_state.command_w Requested value gpCh[channel_idx]^.channel_mc_control.mode_and_state.request_r
Commanded, requested value
ST element	.from_state
Data type	UDINT
Value range	Value	Significance / constant
	0	no significance
	1	HLI_IMCM_PROCESS_DESELECTED
	2	HLI_IMCM_PROCESS_SELECTED
	3	HLI_IMCM_PROCESS_READY
	4	HLI_IMCM_PROCESS_ACTIVE
	5	HLI_IMCM_PROCESS_HOLD
	6	HLI_IMCM_PROCESS_ERROR
Special features	This element does not need to be programmed when the operation mode is changed. However, if a value is specified, a check is conducted when the operation mode is changed to establish whether the CNC is actually in the specified operation mode. A warning is issued if this is not the case.

Target operation mode when the operation mode is switched over
Description	Operation mode to which the system is to switch.
ST Path	Commanded value gpCh[channel_idx]^.channel_mc_control.mode_and_state.command_w Requested value gpCh[channel_idx]^.channel_mc_control.mode_and_state.request_r
Commanded, requested value
ST Element	.to_mode
Data type	UDINT
Value range	See “Operation mode actual value on operation mode change” → Value range

Target state when operation mode is changed
Description	Target state within the target operation mode.
ST path	Commanded value gpCh[channel_idx]^.channel_mc_control.mode_and_state.command_w Requested value gpCh[channel_idx]^.channel_mc_control.mode_and_state.request_r
Commanded, requested value
ST element	.to_state
Data type	UDINT
Value range	See "Actual value of operation mode state for operation mode change" → value range

	If the target state = RESETTING = 15 is specified, a CNC reset is executed explicitly. This function is available as of the following Build: V2.10.1033.01 and higher V2.10.1507.02 and higher V2.10.1800.04 and higher

Parameters for operation mode change
Description	Parameters for operation mode change. It may be necessary to specify parameters when commanding an operation mode change to ensure the successful change to a specific state of an operation mode. These parameters are saved in this element.
ST path	Commanded value gpCh[channel_idx]^.channel_mc_control.mode_and_state.command_w Requested value gpCh[channel_idx]^.channel_mc_control.mode_and_state.request_r.
Commanded, requested value
ST element	.parameter
Data type	STRING(HLI_IMCM_MODE_STATE_PARAM_STRL)
Special features	The string for the AUTOMATIC operation mode is limited to a maximum of 83 characters. It is advisable to use the parameters of file paths with longer strings. See P-CHAN-00401 to P-CHAN-00404.

If an operation mode change is commanded, it may be necessary to specify a parameter so that commanding can be executed successfully. The table below lists the cases where this is necessary and what type of parameter needs to be transferred.

If one of the listed state transitions is involved in the operation mode and state change, the corresponding parameter must be specified. Use the "State graph of other operation modes" to determine whether one of the state transitions listed below is executed in the case of a commanded operation mode change.

Meaning of the parameter string in conjunction with the operation mode

The NC kernel only adopts the content of the “parameter” structure element if a state transition is executed from SELECTED to one of the states READY, ACTIVE or HOLD.

Operation mode setpoint	Parameter
Automatic mode	The NC program name as character string.
Manual block	NC block (blocks)
Manual mode	no parameter: all axes are activated (G200) explicit activation of specific axes with G200[Axis_1, ...] General NC block sequence comprising several lines, e.g. activate a kinematic #KIN ID[1] $R$N G200 $R$N: String denoting line break in IEC61131-3
Homing	no parameter: NC program rpf.nc is started explicit selection of axes by manual block (e.g.: G74 X1 Z2 )

Channel number
Description	Number of the channel whose operation mode is to be switched over.
ST path	Commanded value gpCh[channel_idx]^.channel_mc_control.mode_and_state.command_w Requested value gpCh[channel_idx]^.channel_mc_control.mode_and_state.request_r.
Commanded, requested value
ST element	.channel_number
Data type	UDINT
Special features	Not used (only for compatibility with the HÜMNOS standard).
