Configuration Scheme - Siemens SIMATIC Ident Function Manual

Description

2.2 Configuration scheme

Data is transmitted to the tag and data is transmitted between the CM and FB 45 at the
same time. Usually no further time must be added for data transmission between the CM
and FB 45 so that the time t
However, commands may require more time under the following conditions.
● A very large number of RFID channels are processed in parallel.
● Very few (or only one) system resources are available for non-cyclic frames.
● Slow transmission speeds are used on PROFIBUS.
● Other applications are running on the S7 which require the non-cyclic frame services
● High-speed identification systems are used (e.g. RF300).

*) These values are exemplary whenever only data structures of the UDT 10 type are arranged in succession.
These values change if UDT 10 is followed by a command structure (UDT 20).
Params_DB and Params_ADDR form a pointer to a data structure. This data structure is
defined by calling UDT 10 (English) or UDT 11 (German). A separate data structure must be
defined for each RFID channel (reader).
