VAR_INPUT

VAR_INPUT
    bExecute  : BOOL;                 (* Function block execution is triggered by a rising edge at this input.*)
    tTimeout  : TIME  := DEFAULT_ADS_TIMEOUT;     (* States the time before the function is cancelled. *)
    sAmsNetId : T_AmsNetId;               (* keep empty '' for the local device *)
END_VAR

bExecute	The function block is called by a rising edge on the input bExecute, if the block is not already active.
tTimeout	Specifies a maximum length of time for the execution of the function block.
sAmsNetId	For local access don't specify this input or allocate an empty string. For remote access to another computer specify its AMS Net Id.

VAR_OUTPUT

VAR_OUTPUT
    bBusy               : BOOL;
    bError              : BOOL;
    nErrID              : UDINT;
    iErrPos             : USINT;
    stMDP_ModuleContent : ST_MDP_IdentityObject;
END_VAR

bBusy	This output is TRUE if the function block is active.
bError	Becomes TRUE as soon as an error situation occurs.
nErrID	Returns an error code if the bError output is set.
iErrPos	If an error occurred and this refers to an individual element, then this output indicates the position (subindex of the element) at which an error first occurred.
stMDP_ModuleContent	The information from the table is displayed at this output in the form of the structure ST_MDP_IdentityObject.
