Configuring The Analog Inputs - Siemens SIMATIC S7 System Manual

PLC device configuration
6.1 Configuring the operation of the PLC system
Hardware options
You can also configure the CPU to allow RUN mode operation under the following hardware
conditions:
● One or more devices specified in the hardware configuration stored in the CPU are
missing.
● A difference exists between the hardware configuration stored in the CPU and the
devices actually present, resulting in configuration errors (for example, discrete input
module in place of a configured discrete output module).
If you deselect one or both of the selections, the CPU is prohibited from entering RUN mode
if any of the disallowed conditions are true.
6.1.8

Configuring the analog inputs

Click the Analog Inputs node of the system block (Page 133) dialog to configure options for
an analog input module that you have selected in the top section.
Analog type configuration
For each analog input channel, you configure the type to be either voltage or current. The
type selected for the even-numbered channels also applies to the odd-numbered channels:
the type selection for Channel 0 also applies to Channel 1, and the type selection for
Channel 2 also applies to Channel 3.
