Application Scenarios
Picture a 132 kV transmission substation in a mountain ring-main scheme. The RTU560 rack lives in the relay house: a 560CMR01 R0001 in the central slot, a 560PSR00 redundant supply behind it, 560BIR01 binary inputs on the breaker auxiliary and trip-circuit contacts, 560AIR01 analogues on the transformer tap and tank-temperature transducers, and a 560RTC01 feeding the station time. Upstairs, the utility’s SCADA master polls the station over IEC 60870-5-104 on E1, while E2 faces the local maintance LAN for the web server and a second DNP3 outstation feed to the regional DMS.
One January cold snap, the web session is unreachable, E1’s link LED is dark, and the SCADA historian starts logging stale quality flags — but the protection relays are still picked up and the breakers are fine. The station is “blind,” not unsafe, and the on-call engineer has four hours before the next dispatch window. Because the 560CMR01 R0001 is a single-slot, hot-serviceable CMU, the swap is mechanical: eject the suspect unit, seat a tested spare with the SD card carrying the site configuration, confirm the RTC holdover is within drift, and watch E1/E2 and the SPB activity LEDs come back. The SCADA gap closes inside the dispatch interval, the event time stamps stay monotonic, and nobody has to explain a missed feeder reclosure alarm to the regulator.
Parameter
| Main Parameters | Value / Description |
|---|---|
| Product Model | 560CMR01 R0001 — RTU560 Communication Unit (CMU), central module |
| Ordering / Product ID | 1KGT036200R0001 (global commercial alias 560CMR01 R0001; successor-era cross-ref 3BSE022354R1 appears in third-party stock records — verify against your asset list) |
| Manufacturer | ABB Grid Automation (product line now under Hitachi Energy following the 2020 acquisition); country of origin DE (Germany) per the ABB commercial record |
| Product Category | RTU560 Communication Unit / CMU — controller-class communication and I/O management module |
| Processor | 32-bit ARM Cortex-A8, TI AM3352 @ 800 MHz. This is the “factor 3–4” CMU platform ABB cites over the earlier generation |
| Memory | 128 MB RAM + 8 MB boot Flash; config and function images live on the removable SD card, so the module is reusable across sites with a card swap |
| Serial interfaces | CP1 & CP2, RJ-45 connectors, independently software-selectable RS-232C or RS-485, 200 bit/s … 38.4 kbit/s. One port typically faces the local HMI/serial console, the other a sub-RTU, IED or meter daisy-chain |
| Ethernet interfaces | E1 & E2, RJ-45, IEEE 802.3, 10/100BaseT, Auto-MDI/MDI-X. Two independent MAC paths — one to the SCADA master, one to the local/maintenance LAN, or LACP-style segregation by design |
| USB / service port | 1× Micro-USB 2.0 device port (up to 480 Mbit/s signalling). Plug a laptop for the webserver diagnostics, firmware load and event/log pull — no engineering station in the relay house required |
| Internal bus | SPB I/O bus (Serial Peripheral Bus) master, via the rear backplane connector. The 560CMR01 R0001 is the bus master; every 560xx I/O module is a slave it scans, times and commands |
| Real-time clock | Battery-buffered RTC, CR2032 3 V lithium, quoted >10 yr life at ambient; 1 s resolution. Time is fed from the 560RTC0x on the backplane, so the CMU is the station time-distribution anchor |
| Storage / licensing | Push-push SD card slot, SD 2.0 Class 2, 4 GB typical. Important: protocol and function licenses are NOT included — IEC 60870-5-101/103/104, DNP3, Modbus, IEC 61850 etc. are licensed per site on the card. A bare module is a paperweight without the licensed SD |
| Security variant | R0001 = standard network-security feature set. The R0002 carries the security-chip build with advanced network-security features. They are NOT interchangeable without re-licensing and a configuration review — confirm the R-number before you swap |
| Physical | 206 mm (L) × 40 mm (W) × 143 mm (H) module body, 0.158 kg net / 0.215 kg gross. 3U Eurocard form factor, plugs into the RTU560 subrack card guide — not DIN-rail mounted despite what the generic listings claim |
| Environment | −25 … +70 °C operating; start-up to −40 °C; +85 °C tolerable for up to 96 h; 5…95% RH non-condensing. IP20 front face, cabinet-mounted. These are the ABB-quoted values, not the “−40 continuous” some brokers publish |
| Power | Drawn from the RTU560 backplane, fed by the rack PSU (560PSR00 24…60 V DC or 560PSU01 110…220 V DC). Budget the PSU redundancy before you budget the module — a starved backplane mimics a dead CMU |
| Diagnostics | Per-port LEDs (E1/E2 link/activity, CP1/CP2 tx/rx, run/fault, SPB activity), browser-accessible diagnostics and internal event log with time stamps |
| Redundancy | The RTU560 permits redundant CMUs (up to 16 CMUs in the product line architecture) and redundant PSUs, both replaceable under power. A second in the partner slot is the high-availability answer |
| Software / config | ABB Station Automation / engineering tooling; configuration persists on the SD card. Web server is built in. Confirm tool revision against the firmware before you reflash |
| Lifecycle | Listed “as long as available” (made-to-order: No, quote-only in current ABB channels) — effectively a spares-and-migration SKU. The 560CMR02 is the heavier serial-port successor platform; plan the migration, stock the today |
| Compliance | CE, IEC 61131-2 / IEC 61850 context, WEEE-not-in-scope, HS 8517.62.00 / 85371090 depending on jurisdiction |
