A good cellular automation solution based on TCP/IP networking provides anywhere/anytime connectivity and also offers security features that meet the most stringent requirements of industrial standards associations. Cellular automation is a cost-effective solution to customer problems, which integrating cellular data networking to enable SCADA data to be securely communicated from the networking back to the control center, thereby improving safety, productivity and profitability.
Today, most – if not all – remote sites contain legacy serial devices that need to be converted to IP-based services. Some of these devices require special treatment by the gateways they are attached to so that the serial interface can be properly converted to IP, but most solutions don’t offer that type of flexibility.
