Security and visibility are becoming increasingly important in today’s Modbus installations. Engineers are being asked to provide more visibility to Modbus installations, and at the same time, are also being asked to keep devices secure from unauthorized access and errant configuration changes. To make things more challenging, they are also being asked to do more with existing equipment. And let’s not forget the all-too-common limited budgets and tight schedules.
So, how does one add a SCADA or HMI system to an existing Modbus network without compromising the security of existing Modbus devices? How does one design a Modbus installation that limits control of Modbus slave devices to a single Modbus master and yet can provide status information from those same device(s)? How does one add additional equipment quickly, easily and economically? And how does one maintain such an installation once it is operational? That is not easy – unless if you have a DeviceMaster UP running Modbus Router.
At Comtrol, we are constantly looking for innovative ways to help solve such challenges. Unique and extensive functionally designed to solve the most difficult problems with ease-of-use, robustness, and maintainability – that is what we are all about.
