The H41q and H51q System Families

Hints to the Structure of the Catalog and

How to Use it

The catalog contains the description of the HIMA Programmable Electronic

Systems (PES) of the system families H41q and H51q.

The introduction contains general hints to the PES and is followed by the

description of the individual types of PES. All the descriptions have the

same structure so that they can each be used independently as device documentation.

The data sheets of the assembly kits complete the device

documentation. They are listed in the order of their component identification

numbers (B xxxx). Each type of PES has a corresponding assembly

kit (see 3.9 and 4.9, overview of assembly kits).

The data sheets of the central modules and IO modules which are usable

in the PES are part of the appendix.

Furthermore, this catalog contains the data sheets for the connection cables

(BV xxxx), hints to external circuits, technical data of the PES and

hints for application.

The programming of the HIMA PES with programming system ELOP II,

startup and maintenance, functions of the operating system, using in safety

systems etc. are described in own manuals. A schedul of all HIMA documentations

is listed in the USD (Update Service Documentation.

10 The HIMA PES

The HIMA PES mainly consists of the H41q and H51q system families.

Both system families are based on the same hardware and software, and

they are the 3rd generation of the field-proven HIMA PES to control preferably

process engineering plants. Additionally personal computers are

used for configuration, logging, operation, and trend recording.

Digital and analog inputs can be processed. Some input modules are designed

for intrinsically safe circuits as well as for electric position sensors

(proximity switches) according to DIN 19234. Digital and analog outputs

are also available.

The HIMA PES are installed in subracks 19 inch 5 resp. 4 units high. The

H41q system family is a compact system consisting of a subrack holding

all components such as central unit, power supplies, fusings, and power

distribution, as well as input/output modules.

The H51q system has a modular structure. A central rack 5 units high containing

the central unit, interface port extensions, monitoring, and power

supplies may have up to 16 associated input/output subracks 4 units high.

The following diagram provides support in selecting the appropriate system

for your PES task (see to the following page):

Conception of the HIMA PES

The HIMA PES of the H41q and H51q system families consist of module

for central devices assembled in one subrack 5 units high 19 inch and of

modules for binary and analog input/output signals which are assembled

in H51q in 4 units 19 inch subracks.

The HIMA PES use personal computers with the programming system

ELOP II for the configuration, monitoring, operation and documentation.

The entry of the user’s program and the compilation into the machine code

is done only on the personal computer without connected PES. To load,

test and to monitor the PLC the personal computer is connected via a serial

interface or a bus system together with the PES.

2.1 Safety and Availability

HIMA PES are designed both for safety related applications up to requirement

class 6 (class derfinition according to DIN V 19250) and for

high availability. Depending on the required safety and availability, HIMA

PES can be supplied as one-channel or two-channel (redundant) devices

with the same modules in the central device as well as in the input/output

level. Redundant modules increase the availability as in case of the failure

of one module this is automatically switched off while the redundant module

continues operation.

2.2 Designs and Types of the PES

The controls can be adapted to the requirements of the plant by equipping

them with the appropriate central modules. The following structures are

possible with the H41q resp. H51q system family:

3 The H41q System Family

The H41q system families comprises compact designed PES in single

channel and redundant models, also with TÜV safety certificate .

All testable input/output modules can be used with both redundant and

single channel models of the central modules.

All modules of the H41q system family meet the requirements for Electromagnetic

compatibility and immunity according to article 10 of the EGguidline

89/336/EWG for the electromagnetic conformity. This is demonstrated

with the vsign within the data sheets of the modules. Also

the systems and modules are wearing a sticky label with this sign.

All models of the H41q system family have all the components required for

control tasks in a 19 inch subrack 5 units high with an integrated cable

tray.

– Depending on the system model, one or two central modules controlled

by micro processors

– Two interfaces RS485 on the central module for a transfer rate of up to

57600 bps

– The central module generates a watchdog signal to switch off the

testable output modules as the second way of switch off in the case of

a fault

– One or two power supply modules 24 V DC/5 V DC to generate the

5 V DC operating voltage for the central modules and the control

voltage for the input/output modules

– Batteries mounted on the rear of the subrack to buffer the sRAM area
