Control Board SDCS-CON-4
Layout of the control board SDCS-CON-4
Memory circuit
SDCS-CON-4 board is equipped with FlashPROM which contains the firmware plus the stored
parameters. Parameters handled by DCS800 panel or DWL, PCtool or by Serial communication
parameter service are stored immediately in the FlashPROM.
Parameters handled by cyclic serial communication (dataset table Group 90 - 92 and pointers group
51) are not stored in the Flash PROM. They must be stored by means of ParApplSave (16.6) service.
The faultlogger entries are stored in the FlashPROM during power down (auxiliary power supply OFF).
Watchdog function
The control board has an internal watchdog. The watchdog controls the running of the control board
program. If the watchdog trips, it has the following effects:
• Writing to FPROM is disabled.
• Thyristor firing control is reset and disabled.
• Digital outputs are forced low.
• Programmable analogue outputs are reset to zero, 0V.
