• Built-in Firewall with the ability to fully control it;
  • Pre-configured firewall rules can be enabled via web-UI;
  • Unlimited firewall configuration via CLI;
  • DMZ;
  • NAT;
  • Port forward;
  • Traffic rules;
  • Custom rules. 
• DHCP server and client:
  • Static and dynamic IP allocation;
  • DHCP relay. 
• Access control:
  • Flexible access control of TCP, UDP, and ICMP packets;
  • MAC address filter. 
• IEC 60870-5-104 and DNP3.0 TLS encrypted communication line (compliant with IEC62351-3);
• VPN capabilities based on OpenVPN, L2TP, and IPSEC;
  • VPN Servers;
  • VPN Clients; 
• RADIUS user management support;
• Role-based access control (RBAC) (compliant with IEC62351-8);
• Syslog-based remote log delivery;
• Encrypted WEB interface with the ability to use corporate certificates;
• Secured shell access (SSH) for remote management;
• Integrated mobile connectivity allows for avoiding the man-in-the-middle.

Professional rugged Dual-SIM 4G/LTE/3G/2G RTU with Router for professional applications.  The device delivers high-performance, mission-critical cellular communication and is equipped with connectivity redundancy through Dual-SIM failover. External antenna connectors make it possible to attach desired antennas and to easily find the best signal.

Mobile: 4G (LTE)/3G/2G – Cat 4 up to 150 Mbps, 3G – Up to 42 Mbps, 2G – Up to 236.8 kbps (in HW v1.4 since 2020/Q3);

SIM switch: 2 SIM cards, auto-switch  if no network, network denied, data connection fails;

Extra: force technology to connect, disable/enable sim cards and manage pin codes, ICMP for link inspection.

Status: Signal strength, SINR, RSRP, RSRQ, Bytes sent/received;

SMS: ability to send SMS on RTU signals conditions and take internal actions on received SMS messages (including RTU and modem diagnostics, remote control thru SMS ) and integrate remote exchange of data thru SMS messages between WCCLite devices (since FW v1.8).

In industrial, building, and utility applications it is important to collect data from smart meters. WCCLite has the ability not only to connect to meters but as well are able to communicate with meters with its native protocol,  store data internally in the WCCLite internal database, and transmit with any protocol.

WCCLite supports different meter protocols:

• Mbus serial;
• Mbus TCP;
• DLMS / COSEM serial and TCP;
• Modbus RTU/ASCII;
• Modbus TCP;
• IEC62056-21 (Modes: A/B/C);
• IEC 62056-31;
• OBIS;
• VBUS

WCCLite supports scripts based on the LUA programming language.

This functionality can be used to write scripts for interaction with any of RTU signals and networking functions including SMS messages. This unlocks unrivaled customization and flexibility by giving users the capability to build applications and scripts for unique and complex functionality. That enables customers to create smart grid applications for self-healing grids, calculations, and others.

Scripts provides:

• multiple scripts usage;
• run scripts on events or periodically;
• store data in key/value storage and data exchange between scripts;
• use tag-engine data and all attributes of tags (measurements and signals);
• use math and bit operations;
• use time functions;
• send and receive SMS messages.

WCCLite now supports programmable logic (PLC) for distributed industrial process measurement and control systems based on the IEC 61499 standard.

This functionality can be used as regular PLC based on IEC 6131. This unlocks unrivaled customization and flexibility by giving users the capability to build applications for deployment into a single RTU or groups of RTUs. Basically, that enables customers to create smart grid applications for self-healing grids.

IEC 61499 provides:

• A combination of distributed programming language and PLC programming with IEC 61131-3;
• Generic modelling approach for distributed control applications;
• Function Block concept;
• Separation of data and event flow;
