Since Modbus is a client/server (formerly master/slave) protocol, there is no way for a field device to get data by the event handler mechanism (except over Ethernet TCP/IP, called open-mbus) as the client node must routinely poll each field device and look for changes in the data. Meer weergeven Modbus is a data communications protocol originally published by Modicon (now Schneider Electric) in 1979 for use with its programmable logic controllers (PLCs). Modbus has become a de facto standard communication … Meer weergeven Versions of the Modbus protocol exist for serial ports, and for Ethernet and other protocols that support the Internet protocol suite.
