Dynamic IP Assignments for Cellular RTUs
For most cellular solutions, each remote modem as well as the central SCADA server are assigned static public
IPs when establishing bi-directional communication. Yet cellular network carriers charge higher monthly fees
for static, public IPs than dynamic, private ones. Moxa’s ioLogik W5300 series and patented Active OPC Server
allow users to implement dynamic IP assignments for the RTUs. The ioLogik W5300 can automatically establish
communications with the Active OPC Server using a fixed IP, and the Active OPC Server will receive and register
the ioLogik W5300’s IP address and receive or record tag updates accordingly.
