Safety Notes
WAGO-I/O-SYSTEM 750
I/O Modules
1.4 Safety Notes
Warning
Switch off the system prior to working on bus modules!
In the event of deformed contacts, the module in question is to be replaced, as
its functionality can no longer be ensured on a long-term basis.
The components are not resistant against materials having seeping and
insulating properties. Belonging to this group of materials is: e.g. aerosols,
silicones, triglycerides (found in some hand creams).
If it cannot be ruled out that these materials appear in the component
environment, then additional measures are to be taken:
- installation of the components into an appropriate enclosure
- handling of the components only with clean tools and materials.
Attention
Cleaning of soiled contacts may only be done with ethyl alcohol and leather
cloths. Thereby, the ESD information is to be regarded.
Do not use any contact spray. The spray may impair the functioning of the
contact area.
The WAGO-I/O-SYSTEM 750 and its components are an open system. It
must only be assembled in housings, cabinets or in electrical operation
rooms. Access must only be given via a key or tool to authorized qualified
personnel.
The relevant valid and applicable standards and guidelines concerning the
installation of switch boxes are to be observed.
ESD (Electrostatic Discharge)
The modules are equipped with electronic components that may be destroyed
by electrostatic discharge. When handling the modules, ensure that the
environment (persons, workplace and packing) is well grounded. Avoid
touching conductive components, e.g. gold contacts.
1.5 Scope
This manual describes the Digital Input Module 750-630 SSI Transmitter
Interface of the modular WAGO-I/O-SYSTEM 750.
Handling, assembly and start-up are described in the manual of the Fieldbus
Coupler. Therefore this documentation is valid only in the connection with the
appropriate manual.

Description
WAGO-I/O-SYSTEM 750
I/O Modules
2.1.1.3 Description
This module is an SSI interface for the direct connection to an SSI transmitter.
The power supply for the transmitter is derived internally from the power
jumper contacts.
After the interface has given a clock pulse to the sensor, the interface reads the
incoming data and transmits it directly in the form of a data word into the
process image of the PLC or PC. It is possible to factory adjust different
operating modes, transfer frequencies and data widths by means of the control
register.
The operational readiness of the module is indicated via a green function
LED.
Any configuration of the specialty modules is possible when designing the
fieldbus node. Grouping of module types is not necessary.
The field side supply voltage of 24 V for the output module is derived from
adjacent I/O modules or from a supply module.The supply voltage for the
field side is made automatically through the individual I/O modules by means
of power jumper contacts.
Attention
The module has no power jumper contact for receiving and transmitting the
ground (earth) potential. A supply module is required, if the adjacent
modules need to be connected to the earth.
Warning
The maximum current of the internal power jumper contacts is 10 A. When
configuring the system it is important not to exceed the maximum/sum
current. However, if such a case should occur, another supply module must
be added.
The module 750-630 and its variations can be used with all
couplers/controllers of the WAGO-I/O-SYSTEM 750 (except for the economy
types 750-320, -323, -324 and -327).
This description is valid from hardware and software version XXXX3A05...
and up. The version is specified in the manufacturing number, which is part of
the lateral marking on the module.

Process Image
WAGO-I/O-SYSTEM 750
I/O Modules
2.1.1.7 Process Image
Using the I/O module 750-630, a 5 byte input and output process image can be
transferred to the fieldbus coupler / controller via one logical channel. The
data received by the transmitter are stored in 3 input bytes (D0 ... D2). Neither
the input byte (D3) and four output bytes (D0 ... D3) nor the control byte (C0)
are used. The status byte (S0) indicates transmitter or cable errors (only
versions 750-630/000-004, /000-005 and /000-007).
Processing the status byte via the coupler / controller is optional, which means
that accessing or parsing the status information depends on the fieldbus sys-
tem.
Attention
The representation of the process data of some I/O modules or their variations
in the process image depends on the fieldbus coupler/-controller used. Please
take this information as well as the particular design of the respective
control/status bytes from the section "Fieldbus Specific Design of the Process
Data" included in the description concerning the process image of the
corresponding coupler/controller.

2.1.1.8 Adjustable Variation 750-630/003-000
The serial interface module 750-630/003-000 may be parameterized with the
software tool WAGO-I/O-CHECK 2 (Item-No.: 759-302).
The presetting is Baud rate: 9600 baud, data bits: 8, Parity: none, stop bits: 1.
In this mode of operation the module has the same behavior and also the same
process values as the base module 750-630. If another mode of operation is
selected by changing the parameters, then the module behaves according to
the variation with the selected mode of operation.
The parameter dialog box in WAGO I/O CHECK 2 offers selection fields for
the available settings of this I/O module.
The following description is valid for software version 41.
