For
years Modbus over RS-232 or RS-485 serial has been the defacto "safe and
(almost) sane" way to specifiy a multi-vendor systems with the maximum
flexibility in supply. Now, the growing industrial accptance of Ethernet,
the recognition and support for TCP/IP, and the introduction of Modbus/TCP
offers a whole new world of high-speed multi-vendor flexibility. This application
explains what Modbus/TCP is, how easy it is to implement, and easily it
will expand & integrate with existing Modbus/RTU systems.
