Hello, Im trying to stablish a communication with a PLC s7 300 and a IM 151-3 PN using a CP 343-1 lean using TIA 13. When i was stablishing the hardware i the IM didnt detected the de PLC has master. Looking on the rack of the PLC i see that the PLC is on the slot 2 and the CP is on the slot 4 and it doesnt let me move it to slot 3.

Can you help me with this? Or should i stop using TIA and program on simatic manager?

as Daniel sugested, it's easy to write some order number of your CP343 module to upper right Search box and look for Technical data where you can see what functions and options are available to your exact type of module.
