JOB_OVAL DINT 20.0 - Output value for read request.
Per channel you may call the SFB in each case with the
same instance DB, since the data necessary for the
internal operational are stored here. Writing accesses to
outputs of the instance DB is not permissible.
To read/write the registers of the pulse width modulation the request
interface of the SFB 49 may be used.
So that a new job may be executed, the previous job must have be
finished with JOB_DONE = TRUE.
The deployment of the request interface takes place at the following
sequence:
Local data only in
Instance DB
PWM Request interface
Proceeding
VIPA System 300SDeployment I/O periphery
Pulse width modulation - PWM > SFB 49 - PULSE - Pulse width modulation
