Perhaps this technology connected via Profinet might do the job: SIPLUS HCS4200 PROFINET/PROFIBUS DP (siemens.com) I suggest contacting your local Siemens distributor for assistance since they have access to more information as well as direct contacts within Siemens that might suggest an optimal configuration for your specific project.

Hello, the answer is you can use for this challenge the follow modules of S7-1500:
With this modules you can measure the resistance value of the NTC-resistor. To evaluate the right temperature you calculate first the value of the analog input to the resistance value and then with the function LGF_NonLinearInterpolation Library of general functions (LGF) for SIMATIC STEP 7 (TIA Portal) and SIMATIC S7-1200 / S7-1500 With the function LGF_NonLinearInterpolation can you convert the resistance value from the resistor to a temperature value with a interpolation point table. You can find a description for the function LGF_NonLinearInterpolation at chapter 4.12.3 at the manual of the LGF. Hope this is helpful for you. |
