Title: Output trigged on write to PLC
Post by: Bolt on March 16, 2018, 05:17:48 PM

I am using a BRX BX-DM1E-36ER-3-D.

Upon trying to write a (very minor) program change to the PLC, I had THIS (http://forum.hosteng.com/index.php/topic,2173.msg18373.html#msg18373) issue pop up again.

I saved the file and closed DmD .  I re-opened DmD and loaded the saved file.  I wrote the saved file to the PLC.

Upon loading, it seems to have enabled an output that definitely should not have been enabled.

See attached screenshot of the output in a Trend View.

Also attached is screenshot of the logic that controls the output.  V300 has a value written to it deep within a program that was not running.  I have another output that is triggered with the same logic (different V value) that did not enable upon upload.
