Quick start

No special measures are required for the initial commissioning of the EL3783.

The EL3783 can be operated with different types of function. The course of decision making and action of the commissioning is shown below.

The introductory chapters on
- Technology
- Method of operation
- Wiring example and measuring methods
- Example programs

are to be observed for understanding.

1. Mounting

Install the EL3783 as described in chapter Mounting and wiring.

2. Configuration

Create a configuration in the TwinCAT System Manager by manually inserting the terminal or scanning it online. Refer to installation chapter TwinCAT regarding this.

	EtherCAT XML Device Description If the XML description of the EL3783 is not available in your system you can download the latest XML file from the download area of the Beckhoff website and install it according to the installation instructions.

3. Delivery state

The EL3783 is inserted by default in the TwinCAT System Manager with the following settings

Trigger activated by Distributed Clocks
20-fold oversampling
No automatic current measurement range switching, 1 A measuring range setting is fixed

4. Setting the parameters and process data

Distributed Clocks

Deactivate Distributed Clocks if necessary (TwinCAT Reiter „DC” -> „Advanced Settings“ -> Checkbox „Enable“). This is recommended only if the EtherCAT system is to be operated without Distributed Clocks functionality.

Oversampling factor

Specify the oversampling factor within the range of permissible values.

The TwinCAT pull-down menu "Predefined PDO Assignment" sets the valid PDOs for the n-fold "Synchronous Oversampling" here (see illustration).

Quick start 2: — Synchronous oversampling setting, "Process Data" tab

If "DC Oversampling" is desired, select "DC (activate Mode on DC tab)" and adjust the "DC Oversampling" factor on the "DC" tab (see illustration).

Quick start 3: — DC oversampling setting, "DC" tab

Quick start 4: — Possible oversampling factors

CoE parameters

If the default CoE parameters are to be changed, they must be saved for each channel in the CoE.

	Parameterization via the CoE list (CAN over EtherCAT) The terminal is parameterized via the CoE - Online tab (double-click on the respective object) or via the Process Data tab (allocation of PDOs). Please note the following general CoE notes when using/manipulating the CoE parameters: - Keep a startup list if components have to be replaced - Differentiation between online/offline dictionary, existence of current XML description - use “CoE reload” for resetting changes

The CoE settings can also be loaded via the SPS/PLC/Task at runtime.

5. Operation

With voltage/current present, the measured values are now transmitted via the process data, for example in the TwinCAT free-run mode, after restarting TwinCAT.

	Data visualization with TwinCAT Scope2 The TwinCAT Scope2 supports the import of oversampling variables in the case of the EL3783 as well. Please observe the corresponding notes for this.
