I want to comunicate CPU315-2 DP to DCS in Modbus TCP/IP via CP343-1. With the version of the CPU315-2DP how can I download library of Modbus TCP/IP FB Blocks (FB108 MODBUS CP; FB107 MB_CBSRV, FB106 MB_CPCLI) and Modbus_TCP_CP_EXAMPLE files.

Yes, with this CPU you can use "Modbus/TCP CP V5.0" (not V6.0).
