FB_EcGetSlaveIdentity

VAR_INPUT

VAR_INPUT
    sNetId      : T_AmsNetId;
    nSlaveAddr  : UINT;     
    bExecute    : BOOL; 
    tTimeout    : TIME := DEFAULT_ADS_TIMEOUT; 
END_VAR

sNetId: This is a string that contains the AMS network identifier of the EtherCAT master device.

nSlaveAddr:Fixed address of the EtherCAT slave whose CRC error counter is to be read

bExecute: The block is activated by a rising edge at this input.

tTimeout: Maximum time allowed for the execution of the function block.

VAR_OUTPUT

VAR_OUTPUT
    bBusy       : BOOL;
    bError      : BOOL;
    nErrId      : UDINT;
    identity    : ST_EcSlaveIdentity;   
END_VAR

bBusy: This output is set when the function block is activated and remains set until an acknowledgement is received.

bError: This output is set up after the bBusy output has been reset if there has been an error in transmission of the command.

nErrId: Supplies the ADS error code associated with the most recently executed command if the bError output is set.

identity: CANopen Identity object.

Example of an implementation in ST:

PROGRAM TEST_GetSlaveIdentity
VAR
    fbGetSlaveIdentity      : FB_EcGetSlaveIdentity;
    sNetId          : T_AmsNetId := '172.16.2.131.2.1';
    bExecute        : BOOL;
    identity        : ST_EcSlaveIdentity;
    nSlaveAddr          : UINT := 1001;
    bError          : BOOL;
    nErrId          : UDINT;
END_VAR

fbGetSlaveIdentity(sNetId:= sNetId, nSlaveAddr:= nSlaveAddr, bExecute:=bExecute);
identity:=fbGetSlaveIdentity.identity;
bError:=fbGetSlaveIdentity.bError;
nErrId:=fbGetSlaveIdentity.nErrId;
