n Per channel you may call the SFB in each case with the same instance DB. Write
accesses to outputs of the instance DB is not permissible.
n So that a new job may be executed, the previous job must have be finished with
JOB_DONE = TRUE.
n The switching between the modes takes place by the presetting of the pulse number
(JOB_ID = 08h/09h). As soon as you specify a pulse number > 0, you switch to the
pulse train mode, otherwise PWM is active.
Please note that some functions of this block are not available in all
CPUs. If you call a functionality that is not supported, you receive the
error message 04FFh ‘Order no. invalid’ as Return value. More about the
supported functions can also be found in the ‘Properties’ of your CPU.
