Hello. I know nothing but Allen Bradley Products. I know need to program a Modicon M340 PLC. I need to purchase the software package but I am confused when I go to there website. Is it programmed in Unity Pro or Proworx 32?
You need UnityPro you only need the S (or small) version.
UnityPro is used to program the whole current range of plcs. The versions are
S for M340
L for M340, premium and Quantum upto level 6
XL for everything
