autom Posts: 89 Rating: (1)	Hello to everyone, My HWfor 1st station iscp315-2pn/dp (6ES73152EH140AB0) with cp343-1 (6GK73431EX300XE0) and 1 ET200M-RED (6ES71532AR030XA0) the second Redundant station has the same hardware. So My first question is if ican use the CP343-1 (6GK73431EX300XE0 firmware V2.2) for redundant link because There isnt in thetable lists with modules that support software redundancy. And second question is if i can use the above CP343-1 what kind of connection should i establish between two redundant plcs? In manual says ISO connection that means ISO-on-TCP Connection or ISO Transport Connection.

I checked that and has

CP 343-1

6GK7343-1BA00-0XE0
6GK7343-1EX11-0XE0

and not the new one 6GK73431EX300XE0. So i guess that is OK because the new one replace the old with the code 6GK7343-1EX11-0XE0.
Any suggestions would be great.

I would also say that an ISO on TCP link should be ok to use (even though the 1EX30 does support a "pure" ISO link), but would stay away from a "pure" TCP link (as this would require knowledge and/or control over the message lenght (see HERE for more) which you dot have sinceAG_SEND and AG_RECV are embedded inside FB104 SWR_AG_COM). The reason for the above assertion is that the employedAG_SEND and AG_RECV do not "care" about the type of CP (e.g. Profibus or Ethernet) nor about the type of configured connection (e.g. FDL, ISO, ISO-on_TCP etc.). I must admit though that I am at a loss to explain why the SWR manual (as wellas latest online info) still explicitly refers to the 343-1EX11 and ISO. Perhaps others can shed light on this and either confirm my assertions or prove me wrong (I'd like to know for sure now too). I hope this helps
