S5 Application Program
As a prerequisite to the application program listed below, the process input and output data on a
Simatic S5 must be at the peripheral addresses EW/AW32 and EW/AW34. Watch the consistent
treatment of the EW/AW34, as the relative speed must be treated as 16 bit value. For this reason only
use the loading and transfer commands (e.g. L EW34 or T AW 34) for access to EW/AW32. Access
to the control/status word 2 organized in bits is possible via the common logic instructions. The I/O
addresses contain the following information:
EW 32
status word 2
EW 34
speed [%] actual value
AW 32
control word 2
AW 34
speed [%] setpoint
For controlling the inverter only the two control word bits
enable/stop and enable/rapid stop are used.
For controlling the relay on the output terminal 62 of the inverter the output
A32.0 is used. Fig. 59
and Fig. 60 show how the control word 2 and the status word 2 are projected in the Simatic S5.
