General
You must only use screened cable when you are connecting analog
signals. These cables reduce the effect of electrical interference. The
screen of the analog signal cable should be grounded at both ends. In
situations with different electrical potentials, it is possible that a current will
flow to equalize the potential difference. This current could interfere with the
analog signals. Under these circumstances it is advisable to ground the
screen of the signal cable at one end only.
You can use the analog output modules to supply loads and actuators with
current or voltage.
Note!
Please take always care of the correct polarity when connecting actuators!
Please leave the output clamps of not used channels disconnected and set
the
output type
of the channel to "deactivated" in the hardware configurator
from Siemens.
The modules may be parameterized by hardware configuration respectively
at run time by means of SFCs.
The modules have diagnostics capability. The following errors may release
a diagnostic:
•
Error in parameterization
•
Short-circuit recognition
•
Wire-break recognition
