Hello ssantiago your are trying to us the CPU's PN port for the redundancy link which is NOT (yet) supported by the Software redundancy package. Have a look at chapter 5.1, 5.2 & 6.7 of the SIMATIC S7-300/S7-400 Software redundancy for SIMATIC S7 manual which explains what Blocks to use for what type of link and what type of S7. The Which modules can you use when implementing software redundancy? FAQ tells you which CP's you can use. Ond once you established the link you may also find THIS Forum post below useful which lists some of the most common pitfalls when using SWR. I hope this helps |
