| Device data | Description |
| Article number | WCCLite |
| Product Description | WCCLite – mini RTU and gateway |
| Configuration software | WCC Excel utility, Putty, Web browser |
| Warranty | 2 years |
| General | WCCLite features |
| Functionality | Freely scalable RTU with included all supported protocols and functions for utilities, grid and renewables automation solutions. |
| RTU functionality | – Reading Process events from the input/output modules. – Send commands to the output modules. – Communication with sub-devices to collect events and execute commands. – Communicating with control systems and other IOT systems. – Handling the configuration via WEB Browser and Elseta configuration tools; – Monitor communication status with sub-devices. – Sequence-of-Event (SOE). – Execute user scripts to enable custom automation and regulation algorithms. – Connectivity: LAN/WAN, Mobile (4G LTE), VPN. – Firewall (rules-based). |
| 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. |
| Communication interfaces | Interfaces for communication with IEDs, Meters, inverters, SCADA systems etc. |
| Independent Ethernet ports | 2x 10/100 Mbps 10/100Base-T compliance IEEE 802.3, IEEE 802.3u standards, supports auto MDI/MDIX |
| Serial ports | 2x RS485 (Standard ANSI/TIA/EIA-485-A) |
| Serial ports | 1x RS232 (Standard EIA/TIA-232-E) Switchable with RS485 port1 |
| Mobile communication | Available only with integrated WCCLite version with mobile communication module |
| Mobile technology support | 4G (LTE) – Cat 4 up to 150 Mbps, 3G – Up to 42 Mbps, 2G – Up to 236.8 kbps |
| Dual SIM card support | 2 SIM cards, auto-switch cases: weak signal, data limit, no network, network denied, data connection fail |
| Other mobile info | Signal strength (RSSI), SINR, RSRP, RSRQ, RSCP, IMSI, ICCID, Signal strength LED indicators, SMS receive/send, APN management. |
| LED indication | To indicate traffic on the interface every interface has an independent LED indication on the receive/send packet. |
