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.

Appropriate housing (per 2014/34/EU) is required when operating the WAGOI/O-SYSTEM 750 in hazardous environments. Please note that a prototype test

24 V or AI2 … AI8 and each 24 V. The channels have a common reference potential. The assignment of the connections is described in the “Connectors” section. Connection examples are shown in section “Connect Devices” > … >

“Connection Example(s)”.

The input signal is electrically isolated and is transmitted with a resolution of 12 bits.

The field voltage and the system voltage are electrically isolated from each other.

The operational readiness and the trouble-free internal data bus communication of the channels are indicated via a green function LED.

One red error LED per channel indicates a short circuit or a measurement underrange/overrange.

For sensor types 3.6 ….. 21 mA and 4 … 20 mA, the red error LED also indicates a wire break.

The meaning of the LEDs is described in the “Display Elements” section.

Power to the internal electronics is supplied via both the internal data bus and the field supply.

The I/O module 750-496 (8AI 0/4-20mA S.E.) receives the 24 V voltage supply for the field level from an upstream I/O module or from the fieldbus coupler/controller via blade-formed power jumper contacts. It then provides these potentials to subsequent I/O modules via spring-formed power jumper contacts.

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.

The 750-496 I/O module provides 1 status byte (8 bits) and 1 data word (16 bits) per channel.

The I/O module supplies the input current range 0 … 20 mA or 4 … 20 mA or

3.6 … 21 mA (sensor type NAMUR NE43) at a resolution of 13 bits.

The digitalized measured value is transmitted to the process image of the coupler/controller in a data word (16 bits) as input byte “0” (low) and input byte “1” (high). This value is mapped with a resolution of 12 bits on bit B3 ... B14. Status information, which can be evaluated for fault detection, is contained in the two least significant bits (B0 ... B1).

In the case of a measurement underrange or overrange, bits B0 and B1 are set = 1. Bit 2 is not defined and is not evaluated.

4.1 Overview

Presentation of control/status bytes a function of fieldbus coupler/controller!

The I/O module always makes its complete process image incl. control/status bytes available to the fieldbus coupler/controller. The WAGO-I/O-CHECK commissioning tool accesses the complete commissioning process image. The fieldbus coupler/controller uses a different process image to stage cyclic process data via the fieldbus. In the other process image, depending on the fieldbus coupler/controller, the representation of control/status bytes can be suppressed.

5.1 Mounting Sequence

Fieldbus couplers/controllers and I/O modules of the WAGO-I/O-SYSTEM 750 are snapped directly on a carrier rail in accordance with the European standard EN 50022 (DIN 35).

The reliable positioning and connection is made using a tongue and groove system. Due to the automatic locking, the individual devices are securely seated on the rail after installation.

Starting with the fieldbus coupler/controller, the I/O modules are mounted adjacent to each other according to the project design. Errors in the design of the node in terms of the potential groups (connection via the power contacts) are recognized, as the I/O modules with power contacts (blade contacts) cannot be linked to I/O modules with fewer power contacts.

Risk of injury due to sharp-edged blade contacts!

The blade contacts are sharp-edged. Handle the I/O module carefully to prevent injury.

Insert I/O modules only from the proper direction!

All I/O modules feature grooves for power jumper contacts on the right side. For some I/O modules, the grooves are closed on the top. Therefore, I/O modules featuring a power jumper contact on the left side cannot be snapped from the top. This mechanical coding helps to avoid configuration errors, which may destroy the I/O modules. Therefore, insert I/O modules only from the right and from the top.

Don't forget the bus end module!

Always plug a bus end module (750-600) onto the end of the fieldbus node! You must always use a bus end module at all fieldbus nodes with WAGO-I/OSYSTEM 750 fieldbus couplers/controllers to guarantee proper data transfer.

6.1 Connecting a Conductor to the Push-in CAGE CLAMP

The Push-in CAGE CLAMP® connection is appropriate for solid, stranded and finely stranded conductors.

Only connect one conductor to each Push-in CAGE CLAMP® connection!

Only one conductor may be connected to each Push-in CAGE CLAMP® connection. Do not connect more than one conductor at one single connection!

If more than one conductor must be routed to one connection, these must be connected in an up-circuit wiring assembly, for example using WAGO feedthrough terminals.

Terminate both solid and stranded or ferruled conductors by simply pushing them in - no tool required. For all other types of conductors, Push-in CAGE CLAMP® must be opened for connection with an operating tool with a 2.5 mm blade (order no. 210-719).

1. To open the Push-in CAGE CLAMP® insert the actuating tool into the

opening above the connection.

2. Insert the conductor into the corresponding connection opening.

3. To close the Push-in CAGE CLAMP® simply remove the tool - the

conductor is then clamped firmly in place.

• Graphical display of bus nodes

• Display of the measured values

• Settings for the application

• Configuration of the I/O module operating modes

• Parameterization of module, channel and scaling settings

• Calibration of channels and adjustment of analog inputs

• Monitoring

WAGO-I/O-CHECK

You can obtain the WAGO-I/O-CHECK software on a CD under Item No. 759-

302. This CD contains all the application program files and an explanation. You can find a description at the internet page at http://www.wago.com

7.2 Calibrating Measured Values

User calibration serves to compensate for tolerances in electrical components. Calibrate the I/O module by channel to achieve maximum measurement accuracy for each channel.

User calibration by channel required!

Calibrate separately for each channel.

The following sensor types are specified:

The variables in the following equations have the following meaning:

The “Gain” and “Offset” values are required to perform user-defined calibration. The calibration gain is the gain factor. The calibration offset is the offset on the y axis. The following general calibration equation applies:

y = (x + b) × m

The general calibration equation yields the following two equations for calculating the two values sought:

Calibration gain: m = (y2 – y1) / (x2 – x1)

Calibration offset: b = (y1 / m) – x1

Manual Version 1.2.0

Page 67

WAGO-I/O-SYSTEM 750 Commissioning 67 750-496 8AI 0/4-20mA S.E.

7.2.1 Example of Determining Gain and Offset

A two-point calibration method is used. Perform the following steps in WAGOI/O-CHECK:

1. Select a sensor type.

In this example, sensor type 0 … 20 mA (ID1) was selected.

2. Activate user calibration.

3. Set the value for the calibration offset to “0”.

4. Set the value for the calibration gain to “1”.

5. Apply a 24 kOhm resistor in series with a ammeter to an I/O module channel.

Read the current of the measurement device and I/O module.

Example:

Reference current 1 (y1)= 0.9 mA At 1 V is x1 = 0.915 mA

6. Apply a second 1.1 kOhm resistor in series to the same I/O module channel.

Read the current of the measurement device and I/O module.

Example:

Reference current 2 (y2)= 13.7 mA At 9 V is x2 = 13.8 mA

7. Insert all read values into the respective equations to obtain the values for the

calibration gain and offset sought.

Example:

Calibration gain: m = (y2 – y1) / (x2 – x1)  m = (13.7 mA – 0.9 mA)) / (13.8 mA – 0.915 mA) = 0.993

Calibration offset: b = (y1 / m) – x1  b = (0.9 mA / 0.993) – 0.915 mA = −0.008 mA

8. Enter the value calculated for calibration gain (0.993) in WAGO-I/O-CHECK.

9. Convert the result for the calibration offset from milliamps to microamps.

10. Enter the value calculated for calibration offset in microamps (−8 µA) in

WAGO-I/O-CHECK.

7.3 Scaling Measured Values

User scaling serves to adjust the process values. When user scaling is used, the required accuracy of the process value resolution is changed, but not fundamentally limited. User scaling is optional.

The values for “Gain” and “Offset” are required to perform user-defined scaling. The scaling gain is the gain factor. The scaling offset is the offset on the y axis. When these two values are input, a scaled process value is yielded as the result. The following general scaling equation applies:

• y2 = y1 × (Gain / 1024) + Offset

The variables have the following meaning:

The y1 value (unscaled process value) serves as the input value for the user scaling. With user scaling switched off, the y1 value is transferred unchanged to y2.

8.1 I/O Module Behavior in the Event of an Error

The response of the I/O module if a diagnostic is present depends on the configuration for wire break monitoring, short circuit monitoring, underrange/overrange monitoring and upper/lower limiting value monitoring. You can activate or deactivate these diagnostics separately in WAGO-I/O-CHECK (see section “Startup” > … > “Parameterization with WAGO-I/O-CHECK”). The I/O module only allows one error to be indicated. A dedicated bit in the status byte is assigned to each error. The associated status bit is set if an error status is detected. Certain errors cause multiple error statuses to occur. This is why error statuses are given priority levels. In the event of several errors being present, the error with the highest priority will always be displayed.

The following priority levels apply:

The limiting values for detecting an underrange / overrange, a wire break, short circuit or a limiting value underrange / overrange and the output process values are specified in the process image tables (see section “Process Image”).

A general error signals a diagnosed error status. A general error is displayed if one or more of the error statuses named in this section occur or other internal error statuses for the I/O module are present. If there are any of the diagnostics for range violation, short circuit or wire break, the bit for general error is always set.

Note how long diagnostics are displayed!

A diagnosed error status is displayed at least 100 ms even if the detected error status is no longer present in this period. If a higher-priority error status occurs in this period, the higher-priority error status is displayed for 100 ms and the lowerpriority error status is lost.
