Hi,
I am new to siemens system.I am working on a project .
here is the configuration in require.
Redundant CPU (Bumpless transfer)
redundant Power supply for each Redundant rack .
Distributed IO
HIM .
Please suggest me the best hardware for this.
As per my knoweledge it is only the S7-400 that supports hot backup of the cpu.I am not sure if s7-400 has redundant power supply.
I have very limited IO.totaling to 300 .
I would also like to know if there is Modbus communication module in Siemens.
My client requires an option for future integration with this system.
He needs MODBUS communication module . No AB PLC for this.
I hope to hear from you soon.
