FUNCTION_BLOCK FB_PN_IM2_WRITE

Using this function block the PROFINET controller writes all I&M 2 data (Identification & Maintenance) data to a device referenced via the Port input.
The frame structure of the I&M2 function corresponds to the index 0xAFF2 according to PROFINET standard.

VAR_INPUT

VAR_INPUT
    bStart  : BOOL;
    NETID   : T_AmsNetId;(* AMS Net ID from Controller *)
    PORT    : T_AmsPort; (* Port used by Controller to communicate with Device *)
    str_Date : TIMESTRUCT;(*YYYY-MM-DD HH:MM*)
END_VAR

bStart: The function block is activated by a positive edge at this input

NETID: AMS Net ID of the controller

PORT: Port via which the controller communicates with the device (port = Device ID + 1000hex)

str_Date : Writes a date (e.g. date of installation of the device) to the device in the format < YYYY-MM-DD HH:MM >.

VAR_OUTPUT

VAR_OUTPUT
    bBusy       : BOOL; 
    bError      : BOOL;
    iErrorID        : UDINT;
END_VAR

bBusy: When the function block is activated this output is set. It remains set until a feedback is received. While Busy = TRUE, no new command will be accepted at the inputs.

bError: If an error should occur during the transmission of the command, this output is set after the bBusy output has been reset.

iErrorID: Supplies an ADS error number when the output bError is set.
