Key number | |
Description | Logical key number from which tasking originates. |
ST path | Commanded value pMC[channel_idx]^.addr^.MCControlHB_Data.HBKeyControlUnit_KeyX.HBKey_Command.W_LogKeyNr Requested valuepMC[channel_idx]^.addr^.MCControlHB_Data.HBKeyControlUnit_KeyX.HBKey_Request.W_LogKeyNr |
Data type | UINT |
Value range | One of the values defined in the configuration list hand_mds.lis for the characteristic parameters tasten_data[X].log_tasten_nr as logical inching key pair number. |
Start/end of keystroke | |
Description | Start/end of keystroke event and traverse direction of the traversing direction keys in Manual mode |
ST path | Commanded value pMC[channel_idx]^.addr^.MCControlHB_Data.HBKeyControlUnit_KeyX.HBKey_Command.W_Direction Requested valuepMC[channel_idx]^.addr^.MCControlHB_Data.HBKeyControlUnit_KeyX.HBKey_Request.W_Direction |
Data type | INT |
Value range | -1 Start of keystroke, traversing direction negative 0 End of keystroke 1 Start of keystroke, traversing direction positive |
Characteristics | Since compliance with a keystroke involves message-orientated transfer (usage data item), both the Start of keystroke event and the End of keystroke event must be generated by the PLC. |
Lifetime of the key signal | |
Description | If this element has a value not equal to 0, the CNC independently generates the End of keystroke event after receipt of a Start of keystroke event after expiry of the period preset by the number of specified interpolator cycles. |
ST path | Commanded value pMC[channel_idx]^.addr^.MCControlHB_Data.HBKeyControlUnit_KeyX.HBKey_Command.D_LifeTime Requested valuepMC[channel_idx]^.addr^.MCControlHB_Data.HBKeyControlUnit_KeyX.HBKey_Request.D_LifeTime |
Unit | Number of interpolator cycles |
Data type | UDINT |
Characteristics | See Note |
Retriggering, Start of keystroke event | |
Description | Retriggering the Start of keystroke event. If element Lifetime of the key signal has a value not equal to 0, the Start of keystroke event can be retriggered if the Lifetime of the key signal has not yet expired. |
ST path | Commanded value pMC[channel_idx]^.addr^.MCControlHB_Data.HBKeyControlUnit_KeyX.HBKey_Command.X_FRefresh Requested valuepMC[channel_idx]^.addr^.MCControlHB_Data.HBKeyControlUnit_KeyX.HBKey_Request.X_FRefresh |
Data type | BOOL |
Value range | [TRUE = Retriggering the Start of keystroke event, FALSE] |
Characteristics | See Note |
Note: The Lifetime of the key signal and Retriggering of Start of keystroke event elements represent a sort of watchdog function. Their use is indicated in particular if the time response of the PLC is not ensured (e.g. soft PLC as Windows task).
