IOMOD HT User Manual Modbus
Introduction IOMOD HT is used for temperature and humidity data monitoring over Modbus (RTU), IEC 60870-5-103 or IEC 60870-5-101. The advanced version of the device is also capable of switching relays automatically (thermostat function) as configured. Featur...
25 Cyber security
WCC Lite is based on OpenWRT operating system. OpenWrt is described as a Linux distribution for embedded devices. WCC Lite has same functionality as Linux OS including user management. Basic configuration on WCC Lite can be done using web based frontend. More...
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...

26.1 Introduction
SMS receiver is a service responsible for command execution that were received via text message. The service is available on WCC Lite with modem. To use this service a working SIM card is also required. This chapter will describe command types, configuration f...
Cronjob example
Lua device can be configured using cron time expression. This way script execution can be scheduled or executed at certain times. To create such solution, device sheet of Excel configuration should look like this: As seen in this configuration, execution type...
Mathematical Operations With Lua (FW version 1.7)
Mathematical operations can be applied to Lua signals as in any other protocol. This can be done by configuring WCC Lite according to solution needed. To create an example which would test multiple mathematical operations, Excel configuration and Lua script is...
Signal Delay with Lua
For delaying the response of command execution, Lua runner could be used as one of the solutions. In this example IEC104 and Modbus TCP are used. IEC104 protocol sends the command to Modbus and Lua signals and the results are represented as two separate signal...
