KTP1000 DP to CP443-5

Hello Experts!

The plant has an S7-400 with CP443-5 as DP master of remote IOs (ET200M). They want to install an HMI (KTP1000 DP) for local monitoring of signals from the S7-400.

I've done a few DP HMIs in the past but all are connected to onboard DP of S7-300s, but there shouldn't be any difference here right?

The HMI should be able to communicate to an S7-400 via CP443-5 as one of the slave nodes in series with remote IOs ET200M right? 

Thanks!

Hi G_R_E_Y,

yes this should work. The DP Adress is the adress of the CP and for Expansion slot use the Slot of PLC at connection parameters.

 I see. So the DP address of the PLC/Master I'll configure on WinCC Flex's communication would be the CP443-5 address.

What do you mean by "for Expansion slot use the Slot of PLC at connection parameters."?

Thanks!

Hi,

I mean the connection entries in TIA / HMI.

 I can't remember an "expansion slot" configuration on WinCC Flex, and I haven't configure an HMI using TIA yet. Could you maybe send a screenshot for that? Thanks.

Attached is the screenshot of WinCC Flex connection settings. This is still the driver I should use right (well there seems no CP-particular one)? 

So I just have to put the DP address of the CP443-5, it's rack and slot number on the station side, while I can put any DP address that hasn't been used yet on the said CP443-5 DP system on the HMI side? 

How about the "only master of the bus" and "number of masters"? Is the default for both ok? 

Thanks!
