Siemens SIMATIC ET 200PA SMART User Manual

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 regarding connection of loads/actuators in the
SIMATIC S7-300 Automation System, Module Data (

Value ranges of the analog values
The behavior of the analog modules is dependent on the area of the value range in which
analog input values fall.
