Can the Simatic CPU 317-2 PN/DP be used for a remote control and diagnostics?
I'd like to connect to the CPU through internet, check my program and change it if I need.
But maybe Siemens doesn't offer this simple method because haven't any extra cent if this is used. You must to have static IP at you engineering PC and router must to route it to IP which belongs to PLC LAN IP adresses. How to do it - belongs from your router.
