# WIZ550web probable error

## Question

Asked by Orko on 2015-06-11 in General.

I’m working with WIZ550web Baseboard.
On the board there are two LED (called D1 and D2) ; when the card gives an electrical reset , these LEDs do not retain their previous state and is always activated when the power returned . The digital outputs D0 to D7 , if they keep their value when the power returns .
I 'm testing the board using the webpage: “0_Basic_Demopages”.

greetings,

Hi, Orko.
This is not an error. It is intended points.
The purpose of mounting the LEDs, indications for WIZ550web module working status. (Fixed output direction and fixed purpose)
LEDs On/off function of the webpage(On-board LED Status) is an example which can be LED controlled by the webpage.

Other digital I/O’s status (‘Digital I/Os’ on the webpage) is stored when every changes occurred.
The ‘digital I/O’s status’ includes pin’s direction, status and alias.

Regards,
Eric.
