PLC_Reset
The "PLC_Reset" function block can be used to reset a PLC run-time system. When the PLC is reset, the PLC variables are filled with their initial values, and the execution of the PLC program is stopped.
VAR_INPUT
VAR_INPUT
NETID : T_AmsNetId;
PORT : T_AmsPort;
RESET : BOOL;
TMOUT : TIME := DEFAULT_ADS_TIMEOUT;
END_VAR
NETID: It is possible here to provide the AmsNetId of the TwinCAT computer on which the PLC run-time system is to be reset (type: T_AmsNetID). If the PLC reset is to be carried out on the local computer, an empty string can be entered.
PORT: Contains the ADS port number of the PLC run-time system that is to be reset (type: T_AmsPort).
RESET: the block is activated by a positive edge at this input.
TMOUT: States the length of the timeout that may not be exceeded by execution of the ADS command.
VAR_OUTPUT
VAR_OUTPUT
BUSY : BOOL;
ERR : BOOL;
ERRID : UDINT;
END_VAR
BUSY: When the function block is activated this output is set. It remains set until a feedback is received.
ERR: If an error should occur during the transfer of the command, then this output is set once the BUSY output was reset.
ERRID: Supplies the ADS error number when the ERR output is set.
