Wiring - Siemens SIMATIC S7-1500 Manual

This section contains the block diagram of the module and outlines various connection

options.

You can find information on wiring the front connector, creating a cable shield, etc. in the

Wiring section of the system manual S7-1500/ET 200MP

(https://support.industry.siemens.com/cs/ww/en/view/59191792).

You can find additional information on compensating the reference junction temperature in

the function manual Analog value processing

(http://support.automation.siemens.com/WW/view/en/67989094), the structure of a data

record in the section Structure of a data record for dynamic reference temperature

(Page 62).

Note

• You may use and combine the different wiring options for all channels.

• Do not insert the potential jumpers supplied with the front connector.
