Internal bus for programmable controller, supporting the TCP/IP protocol, uses multichannel bus that has channel for TCP/IP and has intelligent controller modules with local IP address and TCP/IP stack
Internal bus for programmable controller, supporting the TCP/IP protocol, uses multichannel bus that has channel for TCP/IP and has intelligent controller modules with local IP address and TCP/IP stack
The internal bus (5) connects all the intelligent modules (20,30) of a programmable controller (50) and allows them to communicate using the TCP/IP protocol. Each module has an IP address (24,34) and a TCP/IP stack(22,32). The bus carries multiple communication channels, allowing simultaneous communication under other protocols in addition to TCP/IP.
