The Modbus Suite for KEPServerEX is a collection of Modbus drivers, bundled together for convenience. Es basiert auf Master / Slave Kommunikation. Since Modbus is a master/slave protocol, there is no way for a field device to "report by exception" (except over Ethernet TCP/IP, called open-mbus)- the master node must routinely poll each field device, and look for changes in the data. This app also accesses your devices' sensor data. In the example In the example below the new Slave Address will become 0x51 (81 decimal) after power reset: Description. The MND Modbus display works with up to 10 Modbus sensors as a master, a slave, a snooper, or even a power source.
