To upgrade the FW of wcc lite, in the web interface go to system -> backup/flash firmware and upload the downloaded sysupgrade file by browsing for it and then pressing flash image. The keep settings box can be marked if the old settings are needed and the FW ...

IEC 61499-1 defines the architecture for distributed systems. In IEC 61499 the cyclic execution model of IEC 61131 is replaced by an event driven execution model. The event driven execution model allows for an explicit specification of the execution order of f...

Overview The WCC Lite contains several internal data points for readout and control which can be accessed via the Pooler service. Configuration Devices section In the devices section, only the protocol, scan_rate_ms and poll_delay_ms are to be configured f...

IEC 64199 standard introduced requirements for a distributed control. This means that multiple devices can change information between them and make their own decisions based on the data they receive from other sources. This enables distributed applications bet...

After the PLC design is finished and debugged, such design can be compiled into FBOOT file and uploaded to one or multiple devices to be used in production. As application being debuggged is not automatically considered as a default application, one should be ...

After a project has been built and binded to an existing Excel configuration, a user would normally want to check if every part is working according to the prior requirements before compiling finished project and uploading it to production. Both 4Diac framewor...

To use WCC Lite as a programmable logic controller, it needs to be configured in a particular way. The PLC functionality of the WCC Lite only allows for the use of data that is has been configured in the Excel configuration spreadsheet. This has been done for ...

The best way to understand basics of 4Diac and WCC Lite collaboration is through an example project. This user manual intends to show the pieces needed to run PLC applications on WCC Lite. It is not intended to be definitive guide on how to use 4Diac IDE or ho...

The PLC functionality in the WCC Lite is implemented using Eclipse 4diac framework, consisting of the 4diac IDE and the 4diac FORTE runtime. The system corresponds to IEC 61499, an extension of IEC 61131-3. For more in-depth instructions and function block r...

Introduction MQTT (short for MQ Telemetry Transport) is an open OASIS and ISO standard (ISO/IEC PRF 20922) lightweight, publish-subscribe network protocol that transports messages between devices. The protocol usually runs over TCP/IP, although its variant, M...

This document is intended to act as a user manual and explain WCC Lite usage in detail. It is expected the person referring to this manual is experienced in programmable logic controllers (PLC), networking (IPv4, ethernet) and the use of the operating system o...

General Various protocols are made to transmit data points as they are generated. This is enough for a lot of systems (e.g. SCADAs) that have their own databases and devices only have to buffer fairly recent messages in case of connection or transmission erro...

Devices that send unencrypted data are susceptible to attacks which might cause deliberate damage to the user system. Therefore it is highly advised to use cryptography to secure the sensitive data. WCC Lite offers means to easily store certificates for their ...

IEC 60870-5-104 Slave is designed not to lose data acquired from Master protocols. The data that arrives from Master protocols is stored in the cache. This data is checked every second to manage further data sending. The data that leaves IEC 60870-5-104 Slave ...

IEC 60870-5-104 protocol (in short IEC 104) is a part of IEC Telecontrol Equipment and Systems Standard IEC 60870-5 that provides a communication profile for sending basic telecontrol messages between two systems in electrical engineering and power system auto...

The IEC 60870-5-103 protocol is a companion standard for the informative interface of protection equipment. Standard IEC 60870-5-103 was prepared by IEC technical committee 57 (Power system control and associated communications). It is a companion standard for...

Configuring datapoints (slave) To use IEC 60870­-5­-101 Slave in WCC Lite, it has to be configured via an Excel configuration. This configuration contains two Excel sheets where parameters have to be filled in ­Devices and Signals. IEC 60870-­5-­101 slave pa...

The IEC 60870-­5-­101 protocol is a companion standard for power system monitoring, control associated communications for telecontrol, teleprotection, and associated telecommunications for electric power systems. Standard IEC 60870-­5­-101 was prepared by IEC ...

IEC 60870 part 5 is one of the IEC 60870 set of standards which define systems used for telecontrol (supervisory control and data acquisition) in electrical engineering and power system automation applications. Part 5 provides a communication profile for sendi...

Devices sheet contains all devices to be configured on the gateway. Each row represents one device and its settings. Following options are required for each device: name - Name of the device. Used for representation only. description - A short description ...
