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 Special Module 750-511, (/xxx-xxx) Pulse Width
Output Module of the modular WAGO-I/O-SYSTEM 750.
Handling, assembly and start-up are described in the manual of the Fieldbus

2.1.2.3 Description
The Pulse width output module 750-511 or 750-511/000-002 is able to
modulate Signed-Integer values to pulse width modulated 24 V output signals
with a constant pulse frequency or periodic time. The On/Off time is given by
values of 16 bits.
The module has two output channels and enables the direct wiring of two
loads with ground (earth) to the connections DO 1 or DO 2, the common 0 V
ground potential and ground (earth), if necessary.
The outputs are short-circuit-protected.
The basic frequency or the period can be parameterized for both channels of
the module together. For the module 750-511 the initial pre-programmed base
frequency is 250 Hz, for the module 750-511/000-002 it is 100 Hz.

Display Elements
WAGO-I/O-SYSTEM 750
I/O Modules
The operational readiness and the trouble-free internal data bus
communication of the channels are indicated via a green function LED.
An optocoupler is used for electrical isolation between the bus and the field
side.
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.
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.
Note
Use an appropriate supply module (e.g. 750-602) if an electrically isolated
voltage supply is required!
The specialty module 750-511 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 for the XXXX3A04... hardware and software
versions. The version is specified in the manufacturing number, which is part
of the lateral marking on the module.

I/O Modules
2.1.2.7 Process Image
Using the I/O module 750-511 or 750-511/000-002, a 6 byte input and output
process image can be transferred to the fieldbus coupler / controller via two
logical channels. The setting of the On/Off times occur in the four output
bytes (D0, D1) or (D2, D3). The four input bytes (D0, D1, D2, D3) and the
status bytes (S0, S1) are not used for the On/Off time settings.
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.
Input data Output data
S0 Status byte 0 C0 Control byte 0
D0 X (no evaluation) D0 On/Off time 1 (low Byte)
D1 X (no evaluation) D1 On/Off time 1 (high Byte)
S1 Status byte 1 C1 Control byte 1
D2 X (no evaluation) D2 On/Off time 2 (low Byte)
D3 X (no evaluation) D3 On/Off time 2 (high Byte)
The programming of the On/Off times occur with the resolution of 10 bits.
The five LSB of the 16 bit are not defined. In the table these bits are
represented with a 'X'. The indication of the hexadecimal and the decimal
numerical values in the table considers the condition ' 0 ' for the first five low
order bits in each case. If these five bits accept the condition ' 1 ', the decimal
numerical value is higher around 31, than indicated in the table.
The MSB will hold the sign and is preset to the null state.

WAGO-I/O-SYSTEM 750
I/O Modules
2.1.2.9 Parameterizing the Period / Pulse frequency
2.1.2.9.1 Register
Either the period or the basic frequency can be predetermined at any time by
the PLC (host) via 2 writeable, non-retentive registers (not protected against
voltage loss):
Register 2: Period (16 bits)
Register 3: Basic frequency (16 bits).
As soon as the basic frequency has been entered, the period is calculated
automatically and entered in register 2.
The modification effects both channels of the bus module.
Default-Value 750-511
Designation Register Value Resolution Value Register
Period of oscillation 2 4000 µs 1 µs / Digit 4000 [0x0FA0]
Pulse frequency 3 250 Hz 1 Hz / Digit 250 [0x00FA]
Default-Value 750-511/000-002

Period of oscillation 2 10000 µs 8 µs / Digit 1250 [0x04E2]
Pulse frequency 3 100 Hz 1 Hz / Digit 100 [0x0064]
The pulse width bus module loads the default values in the registers after
"power-on". The PLC (host) must take this case into account if the required
values differ from the default values.
2.1.2.9.2 Control- / Status byte
The PLC can read and set the registers via the control and status byte (C0, S0)
and the output bytes (D0, D1) in the process image.
The control byte is transferred from the PLC to the module and the status byte
from the module to the PLC.

2.1.3.2 Description
The pulse width output module 750-511/000-001 generates a pulse-width-
modulated 24 V output signal with a variable frequency from 2 Hz to 2 kHz.
The frequency is given by a 10 Bit value with a resolution of 2 Hz per digit.
The On/Off ratio is preset by 50%.
The module enables the wiring of a load with pulse and directional signal. The
pulse signal and the directional signal are each displayed via one output
channel. The direct wiring of loads with ground (earth) is possible to the
connections DO 1 (pulse signal) and DO 2 (directional signal), the 0 V ground
potential and ground (earth), if necessary.
The outputs are short-circuit-protected.
The operational readiness and the trouble-free internal data bus
communication of the channels are indicated via a green function LED.
An optocoupler is used for electrical isolation between the bus and the field
side.

I/O Modules
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.
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.
Note
Use an appropriate supply module (e.g. 750-602) if an electrically isolated
voltage supply is required!
The special module 750-511/000-001 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 for the XXXX3A04... hardware and software
versions. The version is specified in the manufacturing number, which is part
of the lateral marking on the module.
