Product Overview
The ABB 560CMR01 R0001 (ordering code 1KGT036200R0001) is the Communication Unit, or CMU, at the heart of ABB’s RTU560 remote terminal unit platform. In an RTU560 rack it is not just another card — it is the processor and communications manager that everything else hangs on. Downward, the 560CMR01 R0001 owns the internal Serial Peripheral Bus (SPB) backplane link, polling the binary, analog, command and I/O modules in the rack, time-stamping the changes and presenting a coherent real-time data image to the rest of the system. Upward, it is the gateway: two software-selectable RS-232/RS-485 serial ports and two independent 10/100BaseT Ethernet ports give the RTU a path to the substation SCADA, the DMS/EMS, a local HMI, a second redundant RTU or a bank of serial IEDs, all at the same time.
What sits on the board is a 32-bit ARM-class processor running a deterministic real-time environment, paired with 128 MB of working memory and boot flash, and a removable SD card that carries the firmware image, the protocol and function licenses and the site configuration. That separation is deliberate and operationally important: the hardware is generic, and the 560CMR01 R0001 becomes the station you need it to be by loading the licensed protocol stack — IEC 60870-5-101/104, DNP3, Modbus RTU/TCP, IEC 61850 client or generic ASCII master/slave configurations are all provisioned this way rather than soldered to a model suffix. The R0001 hardware revision is the standard-security build; an R0002 variant adds the hardened-security element for sites with stricter key-management requirements.
The value of the ABB 560CMR01 R0001 is the headroom it gives a single rack. RTU560 is specified for up to 16 CMUs across a system, so one station can be a compact pole-top RTU today and a multi-protocol substation hub tomorrow, simply by adding a second 560CMR01 R0001 as the redundant partner and populating more I/O behind it. The module is plug-in, hot-swappable in a redundant pair, and carries a battery-backed real-time clock so event sequences, SOE records and DNP3 time tags stay meaningful through a power interruption. A Micro-USB port gives local webserver and diagnostic access when the network is down or the laptop is air-gapped, which is exactly the interface you want during a commissioning weekend or a storm-driven outage.
ABB positions RTU560 firmly in grid automation rather than general factory automation, and the inherits that discipline: wide operating temperature, conformal-coated industrial construction, a 24 VDC tolerant supply, and the kind of silent, fanless, 24/7 reliability that a transmission substation expects from a device it cannot afford to reboot. The platform is mature and the part is sourced through spares channels now, but the number of installed RTU560 stations — and the fact that a CMU failure takes the whole station offline — is why a tested, license-aware replacement is one of the highest-value spares a utility or EPC will ever keep on the shelf.
