Basics
For basics regarding the basic procedure for connecting loads/actuators to analog inputs
(current outputs) as well as basics of the analog value processing and specifications regarding
the analog value formats used in each case, refer to:
"Automation System S7-300, Module Data" http://support.automation.siemens.com/WW/view/
en/8859629)".
Cables for analog signals
Always use shielded twisted-pair cables for the analog signals. This reduces the noise
interference. You should ground the shield of the analog cables at both ends.
If potential differences exist between the cable ends, an equipotential bonding current may flow
via the shield and disturb the analog signals. In this case, you must provide for a low-resistance
equipotential bonding, and, if necessary, ground the shield only at one end of the cable.
Observe the generally applicable information on connecting loads/actuators in the SIMATIC
S7-300 Automation System Module Data manual on the Internet (http://
support.automation.siemens.com/WW/view/en/8859629).
