Hi Expert,

I want to setup a application for S7-300 and Drive.

I use CPU313C (6ES7313-6CG04-0AB0) as DP Master and FCD300 as Slave. So, I wonder this CPU work fine on this case or not. Because, I saw any application someone use CPU315-2DP. However, I want to save my cost on this application. That is my concern

Otherwise, what is difference config Network "PRO Typ1 Module Consistent PCD" and "PRO Typ1 word Consistent PCD"? Please advise me on this, or some documents..

Any advise

Thanks

Yes, this type of CPU will works pretty good like DP master with FCD300. In Danfoss web page exist a sample project and you can use it...

When configuring the PPO types, a distinction is made between module consistency and word consistency:

Module consistency means that a specific portion of

the PPO is defined as a connected module. The parameter interface (PCV, length of 8 bytes) of the PPO

always has module consistency.

Word consistency means that a specific portion of the

PPO is divided into individual data sectors of word

length (16 bits).

The process data of the PPO may have either module

consistency or word consistency, as desired.

Some PLCs, such as Siemens S7, require special

functions to call modules that are longer than 4 bytes

(in the case of Siemens: ”SFC”, see master manual).

This means that the PCV interfaces of the PPOs can

only be called through the SFC functions in the case

of Siemens (S7).
