Operating Modes; Structure Of Data Record 2: Read Response; Error Codes In Byte 1 Of Data Record - Siemens SIMATIC Distributed I/O System DP/ASi Link Manual

Data record 2 Data record 2 reads the response of the last "WR_REC" write job.
You have to call a "RD_REC" read job by means of data record 2 after every
"WR_REC" write job for the response of the last "WR_REC" write job to be
read.
Table 6-5
Error codes in data You can read out in byte 1 of data record 2 any error code that has been is-
record 2 sued.
If you read data record 2 without executing a write job beforehand, unde-
fined responses of the error codes may occur.
