The RTU should not only report alarms over the SCADA network on a priority basis, it should also keep a date-and-time-stamped record of all alarms and events locally in memory. If the RTU is not in a physically secure zone, a major risk is that anyone can plug-in to—or wirelessly access—the local port that is intended for configuration, taking readings and other, local operations via a PC. The term “RTU” will be used for the electronic monitoring and control device at these locations. As Bill pointed out, if someone can eavesdrop and learn to recognize messages, the party can likely also practice “spoofing,” that is, inject commands, which can operate process equipment or corrupt proprietary information. If the user forgets to sign off, the RTU should automatically do this after a set time. You can expect a maximum of a five-year lifetime from lead acid cell batteries but you should check them at least once per year. If access control is violated and someone manually changes a process equipment setting, the RTU could detect it and report an alarm. … In case the host computer or network fails, the RTU should independently monitor and control the process.
