FB_PN_IM1_WRITE

FB_PN_IM1_WRITE 1:

Using this function block the PROFINET controller writes all I&M1 data (Identification & Maintenance) data to a device referenced via the Port input.
The frame structure of the I&M1 function corresponds to the index 0xAFF1 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 *)
    st_IM_TagFunction  : STRING(32); st_IM_TagLocation       : STRING(22);
END_VAR

bStart : The block is activated by a rising edge on this input

NETID : AMS Net ID of the controller

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

st_IM_TagFunction : With this string the functional description is saved to the device.

st_IM_TagLocation : With this string the installation site is saved to the device.

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..
