FB_MDP_SW_Read_MdpVersion

FB_MDP_SW_Read_MdpVersion 1:

The function block enables the MDP version to be queried. This information is located in the module software in the configuration area of the MDP. (General information on the MDP information model)

The MDP version is independent of the PLC library version. The PLC library version is provided by the function F_GetVersionTcMDP.

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;
    sMdpVersion :STRING(23);    (* complete MDP version as string [e.g.: '1, 0, 4, 47'] *)
    iMajorNbr   :UINT;      (* major number [e.g.: 1] *)
    iMinorNbr   :UINT;      (* minor number [e.g.: 4] *)
    iRevNbr     :UINT;      (* revision number [e.g.: 47] *)
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.
sMdpVersion	The queried MDP version is output as a string at this output.
iMajorNbr	The first position of the MDP version is output as a number at this output.
iMinorNbr	The second position of the MDP version is output as a number at this output.
iRevNbr	The third position of the MDP version is output as a number at this output.
