Description
With the period you define the length of the output
sequence, which consists of pulse duration and pulse
pause.
Range of values:
n Time base 1ms: 1 ... 87ms
n Time base 0.1ms: 0.4 ... 87.0ms
n Time base 1µs: 1 ... 87µs
With the minimum pulse duration you can suppress short
output pulses and short pulse pauses. All pulses or
pauses, which are smaller than the minimum pulse dura-
tion, are suppressed. This allows you to filter very short
pulses (spikes), which can not be recognized by the
periphery.
Range of values:
n Time base 1ms: 0 ... Period / 2 * 1ms
n Time base 0.1ms: 2 ... Period / 2 * 0.1ms
n Time base 1µs: 0 ... Period / 2 * 1µs
There are the following possibilities for project transfer into the CPU:
n Transfer via MPI
n Transfer via Ethernet
n Transfer via memory card
For the transfer via MPI the use of the optionally available extension module EM M09 is
required. The extension module provides the interface X2: MPI(PB) with fixed pin assign-

ment.
The structure of a MPI net is electrically identical with the structure of a PROFIBUS net.
This means the same rules are valid and you use the same components for the build-up.
The single participants are connected with each other via bus interface plugs and
PROFIBUS cables. Per default the MPI net runs with 187.5kbaud. VIPA CPUs are deliv-
ered with MPI address 2.
The MPI programming cables are available at VIPA in different variants. The cables pro-
vide a RS232 res. USB plug for the PC and a bus enabled RS485 plug for the CPU. Due
to the RS485 connection you may plug the MPI programming cables directly to an
already plugged plug on the RS485 jack. Every bus participant identifies itself at the bus
with an unique address, in the course of the address 0 is reserved for programming
devices.
A cable has to be terminated with its surge impedance. For this you switch on the termi-
nating resistor at the first and the last participant of a network or a segment. Please make
sure that the participants with the activated terminating resistors are always power sup-
plied. Otherwise it may cause interferences on the bus.
