TAC Xenta I/O modules do not come online after a download from System Plug-In

[Product_Support]

Issue

• TAC Xenta I/O modules do not come online after a download from System Plug-In
• Rapidly blinking green light on I/O modules show offline status (fast blink)

Product Line

TAC Vista

Environment

Xenta 400 series I/O modules

Cause

• No I/O assigned to the module in the Menta file
• Needs a power cycle after download to associate with the base unit

Resolution

1. Verify that at least one hardware input or output is assigned to a terminal on the I/O module.
   1. If the I/O module is a spare that has been added for later expansion capabilities, it will never associate with the master or report an online status.
   2. If this is the case, assign a "dummy" input to the module temporarily if the rapidly blinking LED is a concern.
2. Sometimes even if all of the correct information is downloaded to the TAC Xenta controller, the green light is still blinking rapidly (not configured) on the TAC Xenta I/O module. If this happens try to power cycle the TAC Xenta controller.
