How to select servers for DCS/PLC system?
For DCS systems : You have to follow as per Vendor/OEM suggestion. As they know which server/os suits their software. we don’t use any custom/own servers especially for DCS systems.
For PLC system : either you can follow vendor/OEM or you can have your setup. some PLC vendors software do not need servers, normal workstations/pc will work. Just make sure their PLC software minimum requirements for the workstations/servers to install.
But in DCS configuration, do we need to consider the IOs of the process while selecting server?
If any limitation is there then it is with respect to DCS software license.
Server has nothing to do with this.
If we buy for more I/O’s then just add license to the DCS software.
DCS CPU’s in system cabinets must have their I/O’s limits, its hardware related, if need more then we have to select next higher end CPU model with more I/O’s.
Thank you so much for your help.
