1.
A new job may be started with
JOB_DONE
= TRUE.
2.
A value to be read of a read job may be found in
JOB_OVAL
in the instance DB at
address 28.
(8009h and Parameter error 8001h)
If you have preset a CHANNEL number greater than 3, the error "Channel no. not valid
" (8009h) is reported. if you have preset a CHANNEL number greater than the maximum
channel number of the CPU, "Parameter error" (8001h) is reported.
The frequency meter is controlled by the internal gate (I gate). The I gate is identical to
the software gate (SW gate).
SW gate:
open (activate): In the user program by setting
SW_GATE
of SFB 48
close (deactivate): In the user program by resetting
SW_GATE
of SFB 48
6.7 Pulse width modulation - PWM
6.7.1 Overview
With the pulse width modulation (PWM) by presetting of time parameters the CPU evalu-
ates a pulse sequence with according pulse/break ratio and issues it via the according
output channel.
