ABB G3HP HENF331132R0021 Digital Signal Processing Module

G3HP HENF331132R0021 Digital Signal Processing Module 

The signal processing module G3HP contains essentially the functions for generating the digital outgoing transmitter signal and evaluating the incoming recelver signal, the alarm display and the programming switches.

The diagnostic connector for a pocket terminal or a PC is located on the front of the module.

The DSP module hardware comprises the signal processor with the data and program memories, the various digital input and output units, the clock supply, a serial interface and a "watchdog".

The digital inputs/outputs and the serial diagnostic interface are controlled via an 8 bit bus, which is completely isolated from the fast 16 bit processor bus. Also connected to this bus are the 4 switches for programming the equipment and the LED displays on the frontplate. The input/output buffers for communicating with the other modules are protected by series resistors and are short-circuit proof up to 24 V.

The signal processor is monitored by a watchdog, which upon picking up instantaneously actuates a common alarm. The alarm relay are located on the alarm interface G3HE and on every relay interface G3HC/D. Their contacts can be selected to be normally open (N/O) or normally closed (N/C).

The input and output of characters via the diagnostic interface is performed by the UART unit and the RS-232 interface converter. As soon as the UART receives a character, it informs the processor by means of a hardware interrupt. The processor reads the character via the 8 bit bus and sends the first character of the text to be transferred back to the UART. The UART requests more characters with further interrupts until the text to be transferred is complete.

The data interface of the receiver converts the line signal to a serial data format. These data are transferred to the processor via the lines FSR, DR and CLKR for further processing. In the transmitter, the data signal DX generated by the processor is read from the DSP's serial shift register with the aid of the clock and the framework information (CLKX and FSX) and transferred to the data interface which converts it to the corresponding line signal for transmission.
