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

6.3

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

6.3
The following program is an example of how to call and scan FC 45 in an application. The
definition of the data structure is described in Section "Data structure definition". The
parameter settings for the MOBY command were set up during the definition of the "MOBY
DB".
Block: OB1 cycle execution
Network: 1
memory bit 1.0 is set: Start MOBY command for 1st SLG
memory bit 1.1 is set: Start MOBY command for 2nd SLG
memory bit 1.2 is set: Start init_run for 1st SLG
memory bit 1.3 is set: Start init_run for 2nd SLG
memory byte 2: OB1 used as edge triggered memory
