Siemens SIMATIC ET 200iSP User Manual

You can learn when the response from the 󹪝eld device was received by cyclically reading data
record DS81 for HART channel 0. The response is always supplied in transparent message format.
Table A-37 FC81: Read the response with SFB 52 into DB81
Explanation
m3: CALL SFB52, DB52
REQ :=M1 Read request
ID :=DW#16#200
INDEX :=81
Module address
Data record number 81
MLEN :=200 Target length
VALID :=M49.7
BUSY :=M49.1
ERROR :=M49.6
STATUS :=MD100
LEN :=MW104
RECORD :=P#DB81.DBX0.0 BYTE 200
U M 49.1
SPB m3
BE
Block status or error information
Target area in DB81
The program part A M 49.1 to SPB m3 is only required if reading is to occur within a block cycle.
As long as the processing status (byte 0 of DB81) is at 3 (waiting, executing), the response has
not yet been received from the 󹪝eld device. As soon as the processing status changes to greater
than 3, the HART request is 󹪝nished.
With a processing status of 4, the request 󹪝nished without errors and the response data can be
evaluated.
With a processing status of 5, the request also 󹪝nished without errors but without response data
from the 󹪝eld device.
With a processing status of 6 or 7, the request 󹪝nished with errors. You can 󹪝nd more detailed
information in byte 1 of DB81 (see table "HART group fault display") and for a HART protocol error
also in byte 2 of DB81 (see table "HART protocol error during response").
