Changing mode of communication modbus TCP/IP from CPU 412 5H to CP 443-1

hello experts ,

1. i need some support for Changing mode of communication modbus TCP/IP from CPU 412 5H using a new redondant module  CP443-1:
2. it was configured to communicate on redondancy with

•  DCS honeywell partner using the CPU 412 5H ,the bloc used MB_PNHSV (FB917) and MODBUS_HPARAM_PN_4 (picture attached of the blocs )
• the same CPU it communicate also with another CPU 412 5FH using put & get function 
• the same CPU communicate also profinet with module ET200 SP

question:

• i want to change the mode of modbus communication using a two newer hardware modules CP-443-1 to communicate with DCS and also i want to stay communicate with the other CPU 412 5FH  & ET 200SP over the CPU 
• how can i do that ? 
• on hardware configuration i know install the module and assign IP adress to CPs 
• how can i change the software ?
• without make interruption on communication

thanks for collaborations 

Hello,

in case you have no time to wait for answer, pls call support / write request.

Hi,

for usage of CP443-1 you need another modbus package: "SIMATIC Modbus/TCP CP". MB_PNHSV is only for communcation via internal PN interface. Without an interruption it will be not possible...

 thank you for replying 

in the liberary i can find exemple of.."SIMATIC Modbus/TCP CP" or i need to install another driver ?

i didn't understand why Without an interruption it will be not possible...??

Can you expalain more 

because as we know the operator need to have all the data on DCS Honeywell and not from siemens HMI to manage the package  

Hi ICSramzi

Here you can find the available packages:

How do you establish a Modbus/TCP communication from a SIMATIC S7-300/S7-400 and where can you find further information?

There are also download and demo installation with manual.

I hope it helps.
