Product Introduction
The ABB 560CMD11 serves as the core Communication Management Unit (CMU) for the RTU560 remote terminal unit platform. It acts as the primary brain for substation automation, managing process events and routing data between local field devices and central control centers.This module provides extensive connectivity through four serial ports and two Ethernet LAN interfaces. It operates on a standard 24VDC supply and features a dedicated front-panel switch to force default IP settings for initial commissioning. (Always confirm whether your specific application requires the R0011 variant with the GPRS modem, as the CPB interface functions are mutually exclusive when the modem is active).
Installation & Configuration Guide
Preparation (10 min)
Ensure the RTU560 chassis is completely de-energized. Observe strict ESD protection protocols before handling the board. Have the RTUtil560 configuration tool ready on your laptop.Removal (5–10 min)
Disconnect all Ethernet, serial, and power cables. Release the board from the backplane connector. Pull the 560CMD11 straight out of the chassis. Inspect the backplane pins for bent contacts or debris.Installation (10 min)
Align the new 560CMD11 with the chassis guides. Push evenly until fully seated on the backplane. Reconnect all communication cables. If replacing a CF card, open the right-side housing screws, swap the card, and close the housing before applying power.Power-On & Test (10 min)
Apply 24VDC power. Set the “Def. IP-Addr” switch to ON to force the 192.168.0.1 default IP. Connect your laptop to port E1 or E2 and ping the module. Use RTUtil560 to push your site configuration, then set the switch back to OFF.
Troubleshooting Quick Reference
- Cannot ping default IP: Verify the “Def. IP-Addr” switch is physically set to ON. Check that your laptop is on the 192.168.0.x subnet.
- Serial comm failure: Confirm the RS485/RS232 wiring matches the RJ45 pinout (e.g., Pin 2 = TA/Rx, Pin 3 = TB/Tx for RS485).
- GPRS not connecting (R0011 only): Ensure a valid SIM card is inserted below the CompactFlash slot. Verify an approved 50Ω SMA antenna is attached. Operating without an antenna can damage the modem.
- ERR LED illuminated: Check the RTU560 firmware release notes for specific ERR LED blink codes. This usually indicates a hardware fault or CF card read error.
- Configuration won’t load: Ensure the CompactFlash card is properly seated. Try reformatting and reloading the firmware via the Web diagnostic tool.
Dimensions, Mounting & Wiring Notes
- Mounting: Slides into standard RTU560 CMU backplane slot.
- Wiring: Front-panel RJ45 connectors for all serial and Ethernet links.
- Power: Rear 3-pole pluggable connector for 24VDC. Terminal X38-2 (-) is internally connected to housing ground via terminal X43.
- Antenna (R0011): 50Ω SMA-RF connector on the housing for GSM/GPRS antenna.
FAQ
What is the difference between R0001 and R0011?
The R0011 variant includes an integrated Quad-Band GSM/GPRS modem and a SIM card slot. The R0001 does not. If you don’t need cellular backup, the R0001 is sufficient.I forgot the IP address. How do I reset it?
Toggle the “Def. IP-Addr” switch on the front panel to the ON position and cycle the power. The module will revert to 192.168.0.1. Remember to switch it back to OFF after configuring.Can I use the CPB port for serial and GPRS at the same time?
No. On the R0011 variant, the CPB interface has two mutually exclusive functions: UART character-based protocols OR GPRS modem interface. You must choose one via the RTUtil560 configuration tool.Do you test the Ethernet ports before shipping?
Yes. Every 560CMD11 is installed in a live RTU560 test rack. We verify both E1 and E2 ports negotiate 10/100BaseT correctly and pass data under load.Is the GPRS modem safe to run without an antenna?
Absolutely not. Operating the R0011 variant without a frequency-tuned 50Ω SMA antenna will damage the GPRS modem chip. Always use the recommended ABB antennas (560ANA01 or 560ANA02).Can I upgrade the firmware in the field?
Yes. Firmware is loaded onto a removable CompactFlash card. You can update it via the Web diagnostic tool without removing the board from the chassis.
