Operating Manual EMGZ309._.EIP

The dialog window (Fig.
14) will open up. Here,
one can enter the cycle
time. This determines
how often the data will
be propagated in the
network. The minimal
cycle time is 2 ms.
Default setting is 10
ms. Basically the cycle
time must be set so
that
the
maximum
speed requirements of
the system are fulfilled.
A fast cycle time leads to more data traffic in the network. That can create
communication bottlenecks. Especially when using several EMGZ309 amplifiers
and other EIP devices in the same network a well balanced data speed is important.

Access to the Tension Values
After the integration of
the amplifier in the
network the tension data
are available in the
global input tags of the
controller and that in the
defined cycle time. In our
example the amplifier
was named
EMGZ309
.
The tension values can
therefore be found under
the
controller
tags

EMGZ309:I Data
Index 0
to 3. Where the values
are assigned to the indices as follows:
Index
Value
0
Tension value in digits
1
Tension value in Newton with 3 decimals
2
Tension value in Pounds [lbs] with 3 decimals
3
Tension value in the configured unit with 3 decimals
The value with Index 4 contains the device state. The access to the data in its value
is marked red in Fig. 15.
