Introduction2.General information about the COM600 series2.1.The COM600 product series are versatile Substation Management Units that help realizesmart substation and grid automation solutions in industrial and utility distribution net-works.They get deployed together with protection and control IEDs, substation devices suchas RTUs, meters and PLCs in dedicated cabinets and switchgear.The COM600 product is an all-in-one unit that functions as:• Communication gateway• Web Human Machine Interface (WebHMI)• Automation controller• Real-time and historical data management unitThe COM600 product series use process information and device data, acquired overEthernet or serial communication protocol interfaces to execute specific substationfunctions and applications. Thus, they are critical building blocks to realize substationsecondary system solutions and in the process solving diverse customer needs.COM600 product series variants and rationale2.2.To facilitate substation and grid automation solutions in IEC and ANSI market areas, avariant-based system similar to Relion® 615 and 620 series is being followed fromCOM600 5.0 release.The main reasons for such an approach are the following:• To ensure all COM600 product series features are advantageously used in end-cus-tomer projects in the medium voltage substation automation domain.• To ensure an optimum feature set to be bundled together to realize specific applica-tions required in IEC and ANSI market areas.• To ensure a future-proof product approach.This release then comprises of two variants, based on the primary intent or applicationare defined as follows:• COM600S IEC – COM600 for substation automation, analysis and data management(for IEC markets)• COM600S IEC is a substation automation, analyzer and data management unitthat integrates devices, facilitates operations, manages communication and runsanalysis applications pertinent to equipment or operations in utility or industrialdistribution substations.• COM600F ANSI – COM600 as distribution automation controller (for ANSI markets)101MRS758267COM600 series 5.0Cyber Security Deployment Guideline
