F3430 German HIMA controller control card

Description

F3430 The 5V DC power supply does not have to be wired separately as it is al

ready installed as part of the subrack.

The 5V DC power is needed by the CPU, the control of the interfaces, and

the I/O modules. It is generated F3430 by a clocked 24 V DC/5 V DC power sup

ply module bearing the F 7130A identification.

The 5 V DC output voltage of the power supply module (for the CPU, I/O,

and the interfaces) are monitored on the central unit checking undervolta

ge or failure.

In case of a faulty power supply module the operating system supplies the

user’s program via a system variable with this information.

In case the 5 V DC system power fails hardware clock and sRAM on the

F3430 central module are buffered by a lithium battery which is also on the cen

tral module.

F3430 two clock-synchronised micro processors

– each mikroprocessor with an own memory, one processor operates

with real data and program and the other one with inverted data and

program

– testable hardware comparer for all the external accesses of both micro

processors, in case of a fault the watch dog will be set to the safe sta

tus and the status of the F3430 processor is announced

– Flash-EPROMs of the program memory for the operating system and

the user’s program usable for min. 100.000 writing cycles

– Data memory in sRAM

– Multiplexer to connect I/O bus, DPR and redundant CU

– Battery backup of the sRAMs via batteries on the central module with

monitoring and on the bus board

– 2 interfaces RS 485 with galvanic isolation. Transm. rate: max. 57600

bps. F3430 Set to 9600 bps and to 57600 bps by switch, or setting also of

other transm. rates by software (the software values have priority)

– Diagnostic display and 2 LEDs for information out of the system, I/O

level and user’s program

– Dual Port RAM for fast memory access to the second central module

– hardware clock, battery backed

– I/O bus logic and connection to the input-/output modules

– Fail-safe watchdog

– power supply monitoring, testable (5 V system voltage)

– Battery monitoring
