i bought an used CX1010 to start wetting my fingers in Twincat. The CX has Twincat 2 runtime and WinCe 6.0 installed, in my laptop I installed Twincat 3 and when trying to set a route to the PLC i always get an error 1796/ADS cannot read/write. After lot of searching in internet my understanding is that Twincat 3 installation cannot get routes to earlier runtimes, and thus i need to update/upgrade it in PLC. It is possible to update by myself the PLC with WES 2009 or later, or do i need to keep WinCE installed and update the runtime from 2 to 3? Or the upgraded runtime needs to be bought directly from Beckhoff?
