Functional Description
The ECCP60-01 executes IEC 61131-compliant ladder and structured control logic for legacy B&R distributed automation racks. It communicates with all I/O, communication, and auxiliary modules via the MULTI/MIDI backplane bus without external gateway hardware.
The front panel features a small digital status readout, manual reset button, and a 9-pin D-Sub TTY port for direct PC programming and live online diagnostics. The galvanic isolation on the TTY port mitigates ground loop noise in plant wiring environments. The hardware watchdog triggers a controlled CPU reset if logic scan execution exceeds configured timeout thresholds to prevent unregulated output states during faults.
All register and flag remanent data persists through full system power loss via an onboard lithium coin cell battery. The real-time clock enables timestamping of alarms, production batch logs, and fault event logs without external timing hardware.
Compatibility Matrix
- Valid Rack Hardware: B&R MULTI-series backplane chassis, B&R MIDI multi-slot racks
- CPU Family Restriction: Must operate within Type B MULTI CPU rack slots; cannot mix Type A and Type B CPUs in the same backplane
- Memory Add-Ons: Requires separate PROM module for permanent program storage; onboard SRAM loses logic on power cycle without external memory
- Field Communication: No native Ethernet/CANopen; TTY port only supports serial programming; fieldbus expansion requires separate rack-mounted communication cards
- System Generation: Designed exclusively for vintage pre-2000 B&R MULTI/MIDI platforms; no backward or forward compatibility with modern B&R X20, X67, or APROL hardware

Pricing Guidance
Listed reseller pricing ranges 330–680 USD, dependent on unit condition, remaining stock quantity, and warranty length.Price subject to market surplus availability; contact supplier for a firm quote with exact unit testing documentation.
Industrial Application Notes
- The onboard backup lithium battery has a rated service life of 5 years; schedule preventive battery replacement during annual plant shutdowns to avoid data loss.
- TTY programming cables require custom pinout wiring; standard RS232 serial cables will not establish communication without signal cross-over modification.
- Maximum scan throughput drops 30% when operating at the 2 MHz clock setting; use 3 MHz mode for high-speed packaging, material handling, or machine tool control.
- The module does not support hot-swapping; full rack power shutdown is mandatory for installation or removal to prevent backplane bus damage.
- Operating temperature range is 0 °C to 60 °C; install forced air cooling for rack enclosures with sustained ambient temperatures above 50 °C. Verify with OEM datasheet for extreme cold storage limits.
Frequently Asked Questions
Q: Does the ECCP60-01 store control logic permanently without an external PROM module?A: No. Onboard SRAM only holds logic while powered. All control programs require a separate PROM/EPROM module for non-volatile storage through power cycles.
Q: Can this CPU run motion control for servo axes natively?A: No. Motion control requires dedicated MULTI/MIDI rack servo axis modules paired with this CPU; the ECCP60-01 only handles high-level motion sequencing logic.
Q: Is the TTY port compatible with modern USB-to-serial adapters?A: Yes, but galvanic isolation circuitry requires a shielded serial adapter; unshielded USB serial converters create communication dropouts in electrically noisy plant environments.
Q: Can multiple ECCP60-01 CPUs run in the same MULTI rack for redundant control?A: The hardware supports multi-CPU coexistence on the backplane, but native hot-redundancy logic is not included. Custom user logic must be written to implement failover between paired CPUs.
