I am working on PCS-7 V8.0 ,in my HW configuration I have CP-443-1,how many ways are available to communication with third party and which protocol

------------

New subject after splitting from cp443-1.

Hello Rajiv;

For a list of supported protocols on the CP 443-1, open the following link:

What differences are there between the Industrial Ethernet CPs of SIMATIC S7-400?

The attached file shows which protocols are supported by different variuations of the CP 443-1.

The list does not include "external" software blocks, such as this Open Modbus/TCP offering from Siemens IT4Industry:

Open MODBUS/TCP for SIMATIC systems - Siemens

And look at the links provided earlier by Hamid Hosseini.

Hope this helps,

Daniel Chartier
