Device description
5.8 SELECT/SET button
Properties of the button on the SCALANCE X204RNA EEC (PRP/HSR):
• If the SELECT/SET button is pressed on the SCALANCE X204RNA EEC (PRP/HSR), the mode LED
goes off (display "PRP"). If the button is released within 5 seconds, the "PRP" mode is
programmed and the device goes through a restart. The SCALANCE X204RNA (PRP/HSR)
behaves in this way only with the factory settings.
• After 5 seconds, the mode LED goes on ("HSR"). If the SELECT/SET button is now released, the
"HSR" mode is programmed and the device goes through a restart.
• After 10 seconds, the mode LED returns to flashing mode (SELECT/SET button can be released
without setting a mode).
• If you have accidentally programmed the wrong mode (e.g. by releasing at the switchover
moment), you can trigger a "factory reset" after the normal startup with the normal SELECT/
SET button functionality (press for > 10 seconds) and reverse the programming.
Position of the SELECT/SET button and C-PLUG
Note
On the SCALANCE X204RNA, the SELECT/SET button is located below the C-PLUG compartment.
On the SCALANCE X204RNA EEC, the SELECT/SET button is on the top of the device in a recess
next to the C-PLUG compartment.
