M100 485 Series Modbus (3G or Verizon CDMA) allows Modbus RTU slave devices with RS-485 interfaces to operate on a TCP/IP network as full Modbus TCP slaves. All Modbus devices with an RS-485 bus can be connected to the TCP/IP network via the M100 485 Series, allowing them all to be accessed by Modbus TCP/IP devices on the network.
Traditional Modbus RTU/ASCII master devices also can be connected to TCP/IP networks using Maestro 100 485 Series, making the device appear to be a full Modbus TCP master on the network. It can directly access Modbus TCP slave devices. It also can access other Modbus RTU/ASCII slaves that are connected to the network via other Maestro modems, as if it is talking directly to a Modbus RTU/ASCII slave. (Consult us for master mode)
