Description

The 5V DC power supply does not have to be wired separately as it is already 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 a clocked 24 V DC/5 V DC power supply module bearing the F 7130A identification. 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 undervoltage and 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 RAM on the central module are buffered by a lithium battery which is also on the central unit.

– 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 state and the status of the 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. 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 project

– 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
