Reset
PLC reset, axis | |
Description | The PLC can be requested to perform a reset via this axis-specific interface. Here the PLC must indicated that it wants to be notified about reset requests by the NC kernel by setting the element enable_w. See also State graph of operation modes |
Data type | LC_CONTROL_BOOL_UNIT, see description of Control unit |
Special features | Consumption data item |
Access | CNC sets command_r to TRUE to command a reset for the PLC. The CNC sets command_r to FALSE after the PLC acknowledges execution of the reset by the state_w element. |

PLC reset, channel | |
Description | The PLC can be requested to execute a reset via this channel-specific interface. Here the PLC must indicated that it wants to be notified about reset requests by the NC kernel by setting the element enable_w. See also State graph of operation modes |
Data type | LC_CONTROL_BOOL_UNIT, see description of Control unit |
Special features | Consumption data item |
Access | CNC sets command_r to TRUE to command a reset for the PLC. The CNC sets command_r to FALSE after the PLC acknowledges execution of the reset by the state_w element. |

Notice
Before a new command and after detecting reset acknowledgement, the state_w state is cleared by the CNC.
