8.9.1 Communication Errors
When firmware and application is downloaded to an I/O module, it can take several minutes to install, restart, and re-establish
communication to the Mark VIe controller. If the ATTN LED is red and flashing at 2 Hz 50%, the IP address has not been
received from the controller. For information on ATTN LED flash codes, refer to the Help file for the specific I/O module and
the section Diagnostics.
• Verify that the terminal board bar code configured in the ToolboxST configuration matches the actual hardware.
• Verify that the terminal board type, including HW Form, in the ToolboxST configuration matches the terminal board in
the actual I/O module.
• Verify that the network cables and switches to the I/O module are plugged in correctly, and that the Link and Activity
LEDs are active.
➢ ➢ To view more troubleshooting information: from the Diagnostics tab, select each diagnostic alarm and press F1.
