4.5 EN311 Reset (Reset Request)
This section describes the EN311 reset procedures. There are three ways to reset an
EN311 as follows:
(1) S controller power on
(2) Reset switch
(3) Reset by a user program running on the S controller
In EN311 reset processing, when one of the above resets occurs, the module first
performs the self-check described below. If the self-check completes normally, the
module switches to standby mode (the parameter setting wait state), thus completing the
reset sequence. If an error is discovered during the self-check, the module goes to the
down state.
• EN311 module self check items
•System ROM check
• System RAM check
• LAN controller check
• Memory check for S controller interface
See section 4.3, "EN311 Operation Modes and Station Statuses", for more information
on the EN311 operating modes.
(1) S controller power on
When power is applied to the S controller, power is also applied to the EN311, and
the EN311 performs its reset processing sequence.
(2) Reset switch
EN311 reset processing is performed when the EN311 reset switch is pressed. This
technique should be used when it is desirable to reset the EN311 without stopping
the S controller.
Usage Recommendations
• When pressing the reset switch, use a pointed object, such as a ballpoint pen, to press the
switch through the hole in the front panels. Be sure to press the switch all the way down.
