The Output Enable signal will turn ON if the Reset signal is correctly input
while the input condition to the Restart function block is ON.
This function block can be used to prevent the machine from automatically
restarting, e.g., when the power to the NE1A-series Controller is turned ON,
when the operating mode is changed (from IDLE Mode to RUN Mode), or
when a signal from a safety input device turns ON.
Functionally, the Reset function block and the Restart function block are
equivalent.
• The Monitored Input and all enabled optional inputs must be ON. And the
Reset signal must be input correctly.
The Monitored Input and all enabled optional inputs must be ON.
If the following condition is met, the Restart Required Indication will become a
1-Hz pulse output.
• The Monitored Input and all enabled optional inputs must be ON. And
Output Enable must be OFF.
If the Reset Signal is set to Low-High-Low, the Reset Required Indication will
turn ON when the next condition is met.
• The Restart signal must be ON.
The Restart Signal can be set in NE1A-series Controllers with unit version 1.0
or later (including Controllers that support EtherNet/IP).
