IEC 61131 IIoT Edge Controller, Straton IDE, VPN router, built-in I/Os

Z-TWS4-RT is a high-performance multifunction controller that combines PLC functionality with data logging, routing, and remote access via an external modem. It is in fact based on StratON IEC 61131-3 softPLC. Equipped with 2 Fast Ethernet ports (which can be managed in LAN/WAN modes), 3 serial ports, and 1 USB host 2.0 port, Z-TWS4-RT supports ModBUS TCP Server, ModBUS RTU Master/Slave, FTP/SFTP Server, HTTP/HTTPS Server, OpenVPN, SSL, as well as IoT protocols (MQTT, OPC UA, HTTP post) and optional Energy Management protocols (IEC 60870-101, IEC 60870-104, IEC 61850).

The controller has 6 configurable general-purpose digital channels and 2 analog inputs. The device is configurable via Z-NET4 environment, and web server, and programmable in IEC 61131-3 environment. It also makes use of 4 GB Flash memory, 512 MB RAM, and a Micro SD slot up to 32 GB. Integrated into the LET'S telecare and remote control platform, Z-TWS4-RT can support Point-To-Point-Telecontrol or Single LAN Telecontrol connections. The device complies with the most stringent cybersecurity standards starting from compliance to penetration test conducted according to OWASP, NIST 800-115, Risk Analysis, and IEC 62443.
