Reading And Writing Data Records - Siemens SIMOCODE pro Programming And Operating Manual

Description of the blocks
4.1 Functions for all blocks
4.1.6

Reading and writing data records

The blocks use SFB 52 "RDREC" function to read and process values from data records,
and the SFB 53 "WRREC" function to process and write values to data records of the
SIMOCODE pro device.
The "Read Data" button in the faceplates is used to update the displayed values by calling
the "RDREC" at the function block.
Reading can only be performed successfully if the function Write to data records "WRREC"
is not executed at the same time.
Read parameter data record
Reading data records is performed irrespective of the current mode.
Write function
It is only possible to write data records if the block is in REMOTE mode to configure current
limits for the SIMOCODE pro module configured with a current measuring module.
Errors when reading/writing data record
The following errors can occur when reading/writing the data record:

The module has the data record, however there are no read data yet.
The module currently processes the maximum possible jobs for a CPU.
The required operating resources (memory, etc.) are currently occupied.
Internal temporary error. Job could not be carried out.
Repeat the job. If this error occurs often, check your installation for sources of
