yes, in ET200M

2, if its possible to proceed, can I use the same program which is being used in S7 300 for configuring under S7 400H?

yes

3. While opening "Parameter" option of CP341[inside old S7 300 SWR program]  in the 'General' tab
KP offline on programming unit  S7WFPB1X  Ver 2.8

SCC offline on programming unit S7WFPB2X Ver 2.5

What does this mean?

These are the versions of the Modbus interpreter/procedure running on CP341.

Hello RIAN Che,
the module 6ES7341-1CH01-0AE0 has not got a flash and the Modbus driver is not part of the firmware. So you need to load the driver if the module was disconnected from power supply.

The Modbus driver is not stored in an SDB when you parameterize it. Therefore you need a PG to transfer it. I think the easiest way is to uninstall the current PTP-Param and to install the old version with which you set up your project.

I think it current version of PTP-Param should work as well, but I did not try it. You need to update your project and to transer the Modbus driver to the CP. If you need to be pretty sure whether this works I recommend to contact Siemens.
