PWMH In the PWM mode, the ratio of the duty cycle to the period is specified via
the process data.
In doing so, 100% duty cycle corresponds to the process data item
0x7FFF. During operation, the period can be specified via the register R2.
This is loaded out of R35 (SEEROM) after a system start and is entered in
R2.
The frequency range is from 245 Hz to 20 kHz (0xFA0 in R2 corresponds
to 250 Hz) with a resolution of 10 bits at 245 Hz, 976 Hz and 3.9 kHz.
PWML In the PWM mode, the ratio of the duty cycle to the period is specified via
the process data.
In doing so, 100% duty cycle corresponds to the process data item 0x7FFF
(32767). During operation, the period can be specified via the register R2.
After a system start, this is loaded out of R35 (SEEROM) and is entered in
R2.
The frequency range is from 2 Hz to 250 Hz (250 Hz corresponds to
0x01F4 in R2).
Frq-Cnt-PWM mode Via the process output data of the control system, the frequency is
specified as 2 Hz per digit. The number of periods output by the terminal is
returned to the control system as process input data. In this operating
mode, the counting direction is defined by the sign of the output data. Here,
2 Hz corresponds to the value 0x0001 and -2Hz corresponds to the value
0xFFFF (signed integer). The frequency ranges from 2 Hz to 2 kHz. The
pulses are output in channel O1 and the counting direction is output in
channel O2. "Down" corresponds to the GND level and "up" corresponds to
the Vcc (24V) level.
The counter is set to the value of the output data with a rising edge of the
control bits 0 (control byte in the process data mode, i.e. bit7 = 0).
The pulse width ratio is defined via R36.
Frq-Cnt pulse mode The frequency is specified as 2 Hz per digit via the process output data of
the control system. The number of pulses output by the terminal is returned
to the control system as process input data. In this operating mode, the
counting direction is defined via the sign of the output data. Here, 2 Hz
corresponds to the value 0x0001 and -2Hz corresponds to the value
0xFFFF (signed integer).
The pulses are output in channel O1 and the counting direction is output in
channel O2. "Down" corresponds to the GND level and "up" corresponds to
the Vcc level.
The frequency range is from 2 Hz to 2 KHz.
The counter is set to the value of the output data with a rising edge of the
control bit0 (control byte in the process data mode, i.e. bit7 = 0)..
The fixed pulse width for all frequencies is defined via R37.
Cnt-Cnt-PWM mode The number of pulses is specified via the process output data. The number
of output periods is returned to the control system as process input data. At
the same time, the pulse width ratio is defined via R36 and the period is
defined via R35. Output is started with a positive edge of control bit 0.
Output can be retriggered with each further edge. The pulses are output in
channel O1, Channel O2 can be started via control bit 2. Acceptance and
simultaneous starting of pulse output is returned as status information to
the control system in status bit0. Status bit1 remains for as long as output
is active and status bit 2 returns the status of channel 1.
