Function
If a Pulse Output Stop Error occurs for pulse output 0, the error
code is written to this word.
If a Pulse Output Stop Error occurs for pulse output 1, the error
code is written to this word.
• Counts up each time protection disable fails (i.e., due to the
protection disable password being input incorrectly).
• Displays the total number of times that protection was disabled
for UM protection and task protection.
• The counter stops counting when it reaches 255 (decimal).
• When all protection has been disabled, the counter will be set
to 00 hex.
This word stores a fixed code that is used to specify the area
when an address is specified as a parameter for a function block
instead of an input-output variable (VER_IN_OUT). This code is
used only by the OMRON FB Library. Do not change the contents
of this word.
