Modbus RTU configuration
Hello all,
Our Modbus RTU configuration is like this, 3 packages transfer serial data between one CPU pm864 800xa in DCS and all other cpu on control network also communicate with other packages like this. because of some interruption in Modbs transfer we are thinking if we could separate in serial communication cards i.e. ci853 and install it on one redundant cpu that we are going to install on control network. I mean we are going to install a individual redundant CPU specific and inclusive or modbus communication. All modbus cards in system structure removed and install on a separate redundant CPU. Now my question is that this kind of installation and configuration would affect whole system or not. Do nt consider the modbus issue and say fix the modus problem, because have lots of modbus packages and this issue can not be solved very quickly. so if you have any idea that this separation of modbus is acceptable or not I would appreciate your response. Thank you very much.
