HIMA F7553 984755302 PLC coupling module

Description

F7553 The 5 V DC power supply does not have to be wired extra as it is already

part of the installation.

To supply the I/O racks the 5V DC power supply with corresponding GND

is available at the rear side of the central rack.

The 5 V DC power needed for the microprocessor system and as control

current for the I/O modules is F7553 generated from the 24 V DC power of the

system via clocked 24 V DC / 5 V DC power supply modules bearing the

F 7126 identification. One central rack can be equipped with a maximum

of 3 power supply modules. F7553 The power supply modules are switched in

parallel. One or two power supply modules are usually able to supply the

PES. A further power supply module is used to increase availability.

F7553 The output voltage of the power supply modules is checked as to under

voltage or failure by the monitoring module F 7131.

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 F7553 hardware clock and sRAM on the

central module are buffered by one lithium battery on the central module.

Two lithium batteries on the power supply monitoring module F 7131 are

to buffer the sRAM on the coprocessor module.

4.5.8 The I/O Bus F7553

The data connection of the I/O level with the central device is established

via the I/O bus. The I/O bus coupling modules are already integrated in the

central rack. With the I/O rack the connection to the I/O bus is via a cou

pling module F 7553 installed in slot 17. The connection of the bus bet

ween the individual subracks is establiblished at the rear side via the

BV 7032 data cable.

In case of an error the plant is to be driven in the safe state. For systems

with a defined safety state this is the lowest energetic state. According to

the defined reaction on faults during operation (refer to the table in chapter

4.1) different levels of shut down are executed.
