Product Description:

The 7CP770.60-1 central processing unit is built by B&R Automation for the System 2003 Controllers series. It provides sequence control, data handling, and field communication functions that coordinate distributed I/O modules on a machine or process line. Within an automation cabinet, it serves as the master device, executing application code and exchanging signals with expansion cards so that sensors, actuators, and higher-level supervisory systems remain synchronized.

The processor completes one instruction in 1.6 µs, and its deterministic task loop repeats every 1 ms, giving motion and logic operations uniform response times. Program code is stored in a 256 KB FlashPROM section, while dynamic variables reside in 100 KB SRAM, allowing moderate-sized applications to run without external memory. Fieldbus capacity is anchored by a CAN port that transmits at 500 kBit/s. The port appears together with an RS232 channel on the rear connectors, so discrete devices and drive inverters can be addressed at the same time. Four analog card positions, integrated battery monitoring, a hardware watchdog, and a 1-second real-time clock resolution support orderly shutdown, fault containment, and basic time stamping of logged values.

The second communication port delivers serial data at 57.6 kBit/s through the 9-pin DSUB socket assigned to the RS232 interface. This arrangement supports human-machine panel updates or modem links without changing the local bus structure. Enclosure sealing conforms to IP20, and overall consumption tops out at 20.0 W, which suits standard control cabinets. The backplane can energize field terminals for sensor excitation and LED indicators. Up to 8 expansion modules, including the four dedicated analog slots, can be mounted on the local bus while staying within the available RS232 and CAN interface limits.
