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

2.1.2 Personnel Qualifications

All sequences implemented on WAGO-I/O-SYSTEM 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 WAGO-I/O-SYSTEM 750 in Compliance with

Underlying Provisions

Fieldbus couplers, fieldbus 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 actuators or higher-level control systems. Using programmable

controllers, the signals can also be (pre-) processed.

The devices 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 devices in wet and dusty

environments is prohibited.

Operating the WAGO-I/O-SYSTEM 750 devices 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 “Device Description” > “Standards and Guidelines” in the manual

for the used fieldbus coupler/controller.

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 using the WAGO-I/O-

CHECK startup tool. Learn what version on WAGO-I/O-CHECK you need in the

table “WAGO-I/O-CHECK Minimum Requirements” in the “Commissioning”

section.

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 sent. There is no parity

generation and dataflow control.

Before starting operation, the connections of the I/O module 750-652 must be

cabled appropriately (see section “Connect Devices” > … > “Connection

Examples”).

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.

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

in conjunction with a second I/O module 750-652. This function is available with

firmware version 03 or higher.

Do not exceed maximum current via power jumper contacts!

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

Greater currents can damage the contacts.

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

exceeded, insert an additional supply module.
