Goals and Symptoms
The ETY4103 cannot find the configured IO Scanner devices after starting the PLC immediately following download
of a UNITY or PL7 application.
Facts and Changes
TSX ETY 4103 version 4.0
Causes and Fixes
Configured IO Scanner devices cannot be found after starting the PLC immediately following a
download of the Premium PLC application. If you try to ping the ETY module, the test fails. If there
are no devices connected to the ETY module and the IO scanner table is configured, the debug
screen in UNITY will not show the error condition correctly. Resetting the PLC using the 'Reset' button
on the PLC or power cycling the PLC corrects the problem.
This is an outstanding issue that is part of another problem which has been fixed in an improvement of
the IO scanner. The fix will be included in the next version of the exec firmware for the ETY4103.
The problem is due to the time that it takes to boot up the CPU being longer than the time it takes the ETY
module's IO scanner to bootup. This was a results of some organizational changes made in 'Executive
Firmware version 4.0'. The problem does not happen if you wait about 30 seconds after downloading
the PLC application.
