Analog Input Scale

4 posts in this topic

Dumb question here. How does mA input appear in register for 140 ACI 030 Analog input. I need to test for 10 mA. Does 3x register appear as an integer 10? No documentation found on analog inputs for any Modicon. Thx for help

The Quantum Hardware Reference Guide (downloadable from www.modicon.com) should explain all of the addressing and data for all of the hardware modules. Look in there.
