The updated NET Concentrator System® (NCS) from Moore Industries provides users with increased options for communications. With the addition of the new EMM Interface Module, the process control and distributed I/O network now comes standard with an Ethernet (MODBUS/TCP) port and dual, independent MODBUS RTU (RS-485) ports. One or both of the MODBUS RTU ports can be configured as MODBUS master ports, allowing the NCS to poll other MODBUS RTU slaves with the network polling functions of a typical MODBUS master.
Previously, the NCS could only act as a MODBUS slave. The update allows the NCS to be used as either a single or dual MODBUS master, allowing it to provide simultaneous Ethernet and dual MODBUS RTU master/slave communications.
