Watchdog: This module can interact with the watchdog, if it is used on base address 240. In this case, the last input with address 255 cannot be used. For details, please refer to the "Watchdog" section, which describes the correct use of the watchdog in conjunction with PCD3 components.6-62PCD3.W2x0Temperature measurement with Pt1000In the temperature range – 50° to + 200°C, the following formulae can be used for working to an accuracy of ± 1 % (± 1.5°C). Repeating accuracy is significantly higher.T[°C]=DV 2.08 - (0.509 • 10-³ • DV)261.8T=temperature in °CDV=digital value (0…1023)Example 1: digital value DV=562 temperature T in °C ?T[°C]=562 2.08 - (0.509 • 10-³ • 562)261,8=51.5°CDV =2.08 • (261.8 + T) 1 + (0.509 • 10-³ • (261.8 + T))DV=digital value (0…1023)T=temperature in °CExample 2: preset temperature T= –10°Ccorresponding digital value DV ?DV =2.08 • (261.8 - 10) 1 + (0.509 • 10-³ • (261.8 - 10))=464Resistance measurement up to 2.5 kΩ
