Read full descriptionHide full description
IPLOG v21 is an application for monitoring and controlling IPLOG PLC systems and for FVE management and monitoring. The application is intended for both system administrators and end users. In combination with the IPLOG system, it enables automation, supervision, and system monitoring. Using the IPLOG web interface, administrators can configure user interfaces and define user roles and permissions. Automation logic is created directly in the IPLOG system using an IEC 61131-3 compliant IDE. This approach allows users to build their own customized industrial automation and monitoring solutions. The application requires an existing IPLOG PLC system and configured hardware.
