Many PLC vendors offer proprietary networking systems that are unique and will not communicate with another make of PLC. This is because of the different communications protocols, command sequences, error-checking schemes, and communications media used by each manufacturer. However, it is possible to make different PLCs “talk” to one another based on the network design.
In PLC Network the major components are, CPU, Remote I/O System, HMI, Field Devices, Field instruments and Network conversion kits. These are wired in different ways either peer to peer of different topology. We are providing services to design network design to use multi-vendor devices in a single system. Based on the IO population and different locations of the field devices we can introduce remote I/O to avoid additional CPU’s. These networks can be design based on the following parameters
