PLC_Start
The function block "PLC_Start" can be used to start a PLC run-time system on a TwinCAT computer. The function block can, for instance, be used to start the PLC on a remote PC.
VAR_INPUT
VAR_INPUT
NETID : T_AmsNetId;
PORT : T_AmsPort;
START : BOOL;
TMOUT : TIME := DEFAULT_ADS_TIMEOUT;
END_VAR
NETID: This parameter can be used to specify the AmsNetID of the TwinCAT computer on which the PLC is to be started (type: T_AmsNetID). If the PLC is to be started 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 started (type: T_AmsPort).
START: 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.
