F3331 HIMA 8-channel safety related output module

Description

F3331 The 5 V DC power supply does not have to be wired separately as it is al

ready installed as part of the subrack.

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

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

modules bearing the F 7130A identification. F3331 The subrack is equipped with

two power supply modules. The power supply modules are paralleled. If

one of them fails, the other supplies the PES.

The 5 V DC output voltage of the power supply modules (for the CPU,

I/O, and the interfaces) are monitored on the central unit checking under

voltage 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

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

tral module.

F3331 The central module of the PES H41q-HR contains the essential functions

demonstrated in the structure of the central module:

– Microprocessor

– 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

– Dual Port RAM for fast memory F3331 access to the second central module

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

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

also of other transmission rates by software (the software values have

priority)

– F3331 Diagnostic display and 2 LEDs for information out of the system, I/O

level and user’s program

– Power supply monitoring

– I/O-Bus logic for the connection to the input/output modules

– Hardware clock, battery backed

– Fail-safe watchdog

– Battery backup of the sRAMs via batteries with monitoring
