18.4 Uploading configuration
As of WCC Lite version v1.4.0, there are three separate ways to import the configuration: import an Excel file via the web interface, generate compressed configuration files and later upload them via the web interface; or generate compressed configuration file...
13.2 Modbus Master
Modbus communication contains a single Master and may include more than 1, but not more than 247 devices. To gather data from peripheral devices, master device request a cluster of slave devices for data. If any device understand that this message is addressed...
13.1 Introduction
Modbus is a serial communications protocol for use with its programmable logic controllers (PLCs). Modbus has become a de facto standard communication protocol and is now a commonly available means of connecting industrial electronic devices. It was developed ...
12.3 DNP 3.0 Slave
Default group and variation sets are used to send static and event values. If master devices support different groups and variations, they can be adjusted in Excel configuration. Wcc-Lite supported variations are provided in Static and Event variations and Co...
12.2 DNP 3.0 Master
Default group and variation sets are used to send commands. If slave devices support different groups and variations, they can be adjusted in Excel configuration. For more information check section Excel configuration. Configuring datapoints To use DNP3 Mast...
12.1 Introduction
DNP3 (Distributed Network Protocol) is a set of communications protocols used between components in process automation systems. Its main use is in utilities such as electric and water companies. It was developed for communications between various types of data...
14.6 IEC 60870-5-104 Slave
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 ...
14.3 IEC 60870-5-101 Slave
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...
18.3 Mathematical functions
Signal value might require some recalculation or signal update prior to being sent. Understandably, existing columns in Excel configuration like multiply, add, bit_select might not be flexible enough. To overcome these limitations, symbolic mathematical expres...
