Control board SDCS-CON-F
Layout
Location
The SDCS-CON-F is mounted on an electronic tray. The electronic tray is put in the housing by means of four
hinges and the SDCS-CON-F is connected with the SDCS-PIN-F through three flat cables.
Memory circuit
The SDCS-CON-F is equipped with a flash PROM that contains the firmware and the stored parameters. It is
possible to handle the parameters by DCS Control Panel, DWL or overriding control. Changed parameters are
stored immediately in the flash with the exception of parameters for cyclic communication via the dataset table
in groups 90 to 92 and pointers in group 51.
In addition, the fault logger entries are stored in the flash during de-energizing the auxiliary power.
Watchdog function
The SDCS-CON-F has an internal watchdog. The watchdog controls the proper function of the SDCS-CON-F
and the firmware. If the watchdog trips, it has the following effects:
− the thyristor firing control is reset and disabled,
− all DI’s are forced low (zero) and
− all programmable AO’s are reset to zero (0 V).
