Firmware Upgrade
To upgrade firmware in ConMod its interface has to be reachable via the Wi-Fi. To do so, connect the ConMod to the meter, turn it on, or connect it to a power source and turn on the wi-fi switch. ConMod then becomes a Wi-Fi access point. To connect to ConMod c...
21 Lua script runner
Introduction Lua is a powerful, efficient, lightweight scripting language. It has been used in many industrial applications with an emphasis on embedded systems. Lua has a deserved reputation for performance. To claim to be "as fast as Lua" is an aspiration o...
20.7 Distributed control application
IEC 64199 standard introduced requirements for 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 betwe...
20.6 Generating and uploading FORTE logic file
After the PLC design is finished and debugged, such a design can be compiled into an FBOOT file and uploaded to one or multiple devices to be used in production. As the application being debugged is not automatically considered as a default application, one sh...
20.5 Debugging an IEC 61499 application
After a project has been built and bound to an existing Excel configuration, a user would normally want to check if every part is working according to the prior requirements before compiling the finished project and uploading it to production. Both the 4Diac f...
20.4 Configuring data endpoints
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 has been configured in the Excel configuration spreadsheet. This has been done for sec...
20.3 Example project
The best way to understand the 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 a definitive guide on how to use 4Diac IDE...
20.2 4Diac framework
The PLC functionality in the WCC Lite is implemented using the 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 blo...
20.1 IEC 61499
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...
22 MQTT
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...

23 Data Export
General Various protocols are made to transmit data points as they are generated. This is enough for a lot of systems (e.g. SCADA) that have their databases and devices only have to buffer fairly recent messages in case of connection or transmission errors. H...
24 Certificates
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 sensitive data. WCC Lite offers means to easily store certificates for their late...
25 Cyber security
WCC Lite is based on the OpenWRT operating system. OpenWrt is described as a Linux distribution for embedded devices. WCC Lite has the same functionality as Linux OS including user management. Basic configuration on WCC Lite can be done using a web-based fron...
15.3 IEC 61850 Client
WCC Lite can be used as a master station to collect data from IEC 61850 compatible server devices such as protection relays. As relays require fast, secure and responsive interfaces, WCC Lite can be considered as a valid option. For additional security, a user...
15.2 IEC 61850 Server
WCC Lite can act as an IEC 61850 server to serve data to remote SCADA systems. For example, WCC Lite can be used to acquire data from various protocols (Modbus, IEC 60870-5-103, etc.), this data can be redirected and propagated further to a single or multiple ...
15.1 Introduction
IEC 61850 is an international standard defining communication protocols for intelligent electronic devices at electrical substations. It is a part of the International Electrotechnical Commission’s (IEC) Technical Committee 57 reference architecture for electr...
1 Overview
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...
IOMOD Utility
Overview IOMOD Utility is a tool created to configure IOMODs with firmware version 2. This tool allows users to connect, configure, and diagnose IOMODs such as 8DI8DO, 8DI4RO, 16DI, 8AI, 4RTD, 4CS4VS, METER, and FPI. The Utility's interface allows users to co...
19 WCC Lite internal signals
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...
