FB_PN_IM1_READ

FB_PN_IM1_READ 1:

Using this function block the PROFINET controller reads all I&M1 data (Information & Maintenance) from 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 *)
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)

VAR_OUTPUT

VAR_OUTPUT
    bBusy             : BOOL;
    st_IM_TagFunction : STRING(32);
    st_IM_TagLocation : STRING(22);
    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.

st_IM_TagFunction : label read out for the function of the device.

st_IM_TagLocation : label read out for the installation site of the device.

bError: In the event of an error during the command transfer, this output is set once the bBusy output has been reset.

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