nanoLine - Class Leading Connectivity
The nanoLine supports a new level of connectivity in its product class with the inclusion of Modbus TCP and Modbus RTU server support. Modbus TCP is used to monitor the nanoLC at a distance by a host computer, larger PLC or advanced HMI, or to integrate the nanoLC into larger systems. Modbus RTU provides connectivity for additional local control or an additional HMI.
With Modbus TCP and RTU, all I/O points, registers, timers, counters, program flags and system flags can be read and written remotely and independently of the program. Multilevel password access control and watchdog timer support are also provided.
The Ethernet communication expansion module supports Modbus TCP. This module is attached to the left side of the nanoLC. Serial communications options modules are inserted into the base unit to provide Modbus RTU connectivity via RS-232 or RS-485.
A USB serial communications option module is also available for configuration, programming and simulation. This module can also provide Modbus RTU connectivity during development and testing.
