2.1.1 Subject to Changes

WAGO Kontakttechnik GmbH & Co. KG reserves the right to provide for any

alterations or modifications that serve to increase the efficiency of technical

progress. WAGO Kontakttechnik GmbH & Co. KG owns all rights arising from

the granting of patents or from the legal protection of utility patents. Third-party

products are always mentioned without any reference to patent rights. Thus, the

existence of such rights cannot be excluded.

2.1.2 Personnel Qualifications

All sequences implemented on Series 750 devices may only be carried out by

electrical specialists with sufficient knowledge in automation. The specialists

must be familiar with the current norms and guidelines for the devices and

automated environments.

All changes to the coupler or controller should always be carried out by qualified

personnel with sufficient skills in PLC programming.

2.1.3 Use of the 750 Series in Compliance with Underlying

Provisions

Couplers, controllers and I/O modules found in the modular WAGO-I/O-

SYSTEM 750 receive digital and analog signals from sensors and transmit them

to the actuators or higher-level control systems. Using programmable controllers,

the signals can also be (pre-) processed.

The components have been developed for use in an environment that meets the

IP20 protection class criteria. Protection against finger injury and solid impurities

up to 12.5 mm diameter is assured; protection against water damage is not

ensured. Unless otherwise specified, operation of the components in wet and

dusty environments is prohibited.

Operating 750 Series components in home applications without further measures

is only permitted if they meet the emission limits (emissions of interference)

according to EN 61000-6-3. You will find the relevant information in the section

on "WAGO-I/O-SYSTEM 750"  "System Description"  "Technical Data" in

the manual for the used fieldbus coupler/controller.

Appropriate housing (per 94/9/EG) is required when operating the WAGO-I/O-

SYSTEM 750 in hazardous environments. Please note that a prototype test

certificate must be obtained that confirms the correct installation of the system in

a housing or switch cabinet.

2.1.4 Technical Condition of Specified Devices

The components to be supplied Ex Works, are equipped with hardware and

software configurations, which meet the individual application requirements.

WAGO Kontakttechnik GmbH & Co. KG will be exempted from any liability in

case of changes in hardware or software as well as to non-compliant usage of

Installation only in appropriate housings, cabinets or in electrical operation

rooms!

The WAGO-I/O-SYSTEM 750 and its components are an open system. As such,

install the system and its components exclusively in appropriate housings,

cabinets or in electrical operation rooms. Allow access to such equipment and

fixtures to authorized, qualified staff only by means of specific keys or tools.

Protect the components against materials having seeping and insulating

properties!

The components are not resistant to materials having seeping and insulating

properties such as: aerosols, silicones and triglycerides (found in some hand

creams). If you cannot exclude that such materials will appear in the component

environment, then install the components in an enclosure being resistant to the

above-mentioned materials. Clean tools and materials are imperative for handling

devices/modules.

Pos: 20.1 /Serie 750 (WAGO-I/O-SYSTEM)/Gerätebeschreibung/Einleitung/Anwendung/SO/Anwendung 750-0652 _Date nausta usch klemm e @ 15\mod_1366288638779_21.docx @ 117310 @ @ 1

The I/O module 750-652 (Serial Interface RS-232 / RS-485) allows the optional

connection of devices with a RS-485, RS-422 or RS-232 interface.

It also provides gateways between the serial interface and the fieldbus systems

supported by the WAGO-I/O-SYSTEM 750.

No higher protocol level is required by the module. Communication to the

associated fieldbus master is completely transparent. This provides for a broader

application scope for the serial interface module. If required, communication

protocols can be configured via fieldbus master.

The 2560 byte input buffer provides for high data baud rates. At lower baud rates,

the data received in lower priority tasks is evaluated without data loss.

The 512-byte output buffer provides fast transmission of larger data strings.

The operating mode of the I/O module can be configured with the start-up tool

WAGO-I/O-CHECK 3.3 (firmware version 03 or higher requires WAGO-I/O-

CHECK version 3.5.3 or higher).

NOTE

The default operating mode is RS-485 half-duplex. The default data transmission

rate is 9600 baud. 1 start bit, 8 data bits and 1 stop bit are send. There is no parity

generation and dataflow control.

Before starting operation, the connections of the I/O module must be cabled

appropriately. (see "Connection examples" section)

In RS-232 mode, the interface works in accordance with the TIA/EIA-232-F and

CCITT V.28/DIN 66259-1 standards.

In RS-485/RS-422 mode, the interface works in accordance with the TIA/EIA-

485-A, DIN 66259 standards.

The connected device can communicate directly with the control unit via the

fieldbus coupler/controller used.

The active communication channel works independent of the fieldbus system used

in full or half-duplex operation at up to 115200 baud.

In the data flow control through RTS/CTS in RS-232 mode, a lead time or follow-

on time can be configured for the I/O module for the RTS signal. This function is

available with firmware version 03 or higher.

Direct data exchange between different fieldbus nodes of the 750 series is possible

in conjunction with a second I/O module. This function is available with firmware

version 03 or higher.

Do not exceed maximum current via power contacts!

The maximum current to flow through the power contacts is 10 A.

Greater currents can damage the power contacts.

When configuring the system, ensure that this current is not exceeded. If

exceeded, an additional potential feed module must be used.
