FB_GetAxisAmsAddr

FB_GetAxisAmsAddr 1:

This block is needed to read the ADS address (NetId and Port) of the IO hardware linked with the axis.

VAR_INPUT

VAR_INPUT
    sNetId    : T_AmsNetId;
    iAxisId   : UINT;
    bExecute  : BOOL;
    tTimeout  : TIME;
END_VAR

sNetid : : It is possible here to provide the AmsNetId of the TwinCAT computer on which the address information of the axis is to be read. If it is to be run on the local computer, an empty string can be entered.

iAxisId: Axis ID.

bExecute: The command is triggered by a rising edge at this input.

tTimeout: ADS Timeout-Delay

 

VAR_OUTPUT

VAR_OUTPUT
    bBusy           : BOOL;
    bError          : BOOL;
    iErrId          : UDINT;
    AxisNetId       : T_AmsNetId;
    AxisPort        : T_AmsPort;
    AxisNetIdBytes  : ARRAY[0..5] OF BYTE;
    AxisChannel     : BYTE; 
END_VAR

bBusy: When the function block is activated this output is set. It remains set until and acknowledgement is received.

bError: If an ADS error should occur during the execution of the command, then this output is set.

iErrId: Supplies the error number when the bError output is set.

AxisNetId:  ADS NetId of the  NC axis hardware.

AxisPort: ADS port number of the NC axis hardware.

AxisNetIdBytes: ADS-NetId as byte array.

AxisChannel: Chanel number of the NC axis hardware (multi channel devices)
