Cyclic Calling Of Fb 45 (E.g. In Ob 1) - Siemens SIMATIC Ident Function Manual

6.3

Cyclic calling of FB 45 (e.g. in OB 1)

The following program is an example of how to call and scan FB 45 in an application. The
definition of the data structure is described in the section "Data structure definition
(Page 70)". The parameter settings for the RFID command were made during the definition
of the "MOBY DB".
Network 1:
memory bit 1.0 is set: Start MOBY command for 1st reader
memory bit 1.1 is set: Start MOBY command for 2nd reader
memory bit 1.2 is set: Start init_run for 1st reader
memory bit 1.3 is set: Start init_run for 2nd reader
memory byte 2: OB1 used as edge triggered memory
x01:
x02:
FB 45 for MOBY U, MOBY D, RF200, RF300
