WCC Lite is a single-box device not require any vendor-specific power supply or other components and can work as a standalone device for applications such as protocol converting, mini RTU without I/O’s, datalogger, etc. WCC Lite is ideal for retrofit projects – as its small footprint allows to fit it into any existing cabinet, while its wide variety of supported protocols and possibility for converting them to each other gives a perfect fit. Additional DI and relay output allow to send information to the SCADA system about power outages and indicate errors on cabinet doors or to use as a simple single command.

Due to the integrated modem feature, WCC Lite with the smallest in the market footprint allows to switch from existing cabling or radio infrastructure to mobile connectivity. WCC Lite has an ideal set of features to become a networking router for small sites including routing, firewall, and VPN features. The high bandwidth of Ethernet and 4G allows to integrate of video surveillance traffic or IED’s remote access for configuration, COMTRADE files, and other needs.

WCC Lite can be used as a small RTU in secondary substations, renewable power plants, and other places with the need to collect and deliver data from various field equipment to SCADA, DMS, or CloudIndustries.eu web SCADA platform.

Data exchange WCCLite can support up to 16 host systems including hot-standby SCADA systems.
Every IEC 60870-5 protocol can have shared or independent buffers of events and support multiple SCADA communications at the same time.
Data collection WCCLite series supports the collection of data from up to 50 sub-devices, e.g. IEDs, meters, IO’s, and Inverters. Each sub-device connected to WCCLite is supervised and shown status on the diagnostic screen.
PLC WCCLite support:
– distributed PLC-based IEC 61499 standard;
– Script execution engine (recommended) to write own programs based on LUA programming language.
Data storage WCCLite provides an archive of all data on non-volatile flash for events, measurements, counter values, and security events.
Time management WCCLite provides a multilevel time management solution CPU supports NTP, IEC 60870, and DNP3 time sync multi-sourcing and IOMOD devices have a time sync option with IEC 60870 protocol firmware.
Time sync sources Multi-time sync options (priority based):
– Internal RTC clock with battery-based memory up to >15 years of lifetime;
– NTP (Network Time Protocol) over TCP/IP;
– IEC 60870-5 time sync support;
– DNP3 time sync support;
– IEC 61850 time sync support.
Time sync precision The time base operates with a time resolution of 1 ms.
