This guide introduces Checker 4G communication and programming, including communication protocols, programming guides, API descriptions, communication examples and software downloads.
This guide explains how to configure and program the Cognex Checker® 4G sensor for network communication. It covers IP address assignment methods including DHCP, static IP, and Link Local Addressing. The document also details integration with industrial protocols such as EtherNet/IP and PROFINET, including device class definitions and message types. It provides step-by-step instructions for connecting across subnets and configuring network settings via the Checker GUI.
The guide includes sections on acquisition and inspection sequences, input/output assembly, and module operations for PLC integration. It also references examples for Siemens PLCs and explains how to access implicit messaging data for device control and status monitoring.
You can configure the sensor to use a static IP address by selecting 'Configure Checker' in the main menu toolbar, then setting the IP settings according to your needs.
The Checker 4G is by default configured to use DHCP, but it can also use Link Local Addressing or static IP.
