6.1.2 Edition Screens
The layout of the edition screens is shown below. Each line has a parameter with its description, its value also
with 4 digits plus comma and the unit. Initially the cursor takes the entire line, indicating only the selection of line
navigation. When the right menu key is pressed, corresponding to the Edit command, the HMI enters the edition
mode and the cursor takes only the field of the value with the unit.
Figure 6.4 Edition screens
In the editing mode, the navigation keys are used to increase and decrease the value shown. The value step to
increment/decrement varies according to the parameter and the value shown, and is done as follows:
■ If the value on the screen is much higher than the increment so that the regular variable increment step listed
in the table is not visible on the digits displayed, then the increment will be done in the least significant digit.
Example: With an increment in the parameter table of 0.001 and a variable shown with a value of 999.0, its
increment would result in 999.001 that would not be shown on the screen, since it has six digits. In this case
the real increment will be 0.1, which is the least significant digit, resulting in 999.1.
■ For values with visible increment, i.e., close to the minimum, the ECW uses the increment value of the
parameter shown in the parameter table. Example: With increment of 0.1 and a value shown of 1.000, the
decrement must result in 0.900.
■ If you keep the increment key pressed, after a few seconds a multiplier will be added to the increment in two
stages. For this, there are three multiplying variables on the configuration screen of the HMI: 30086, 30088 e
30090.
■
For a list of special values (true /false, for example), the user will see only the description of the value. To
check the number relative to that configuration, see the table of parameters.
6.1.3 Event Screen
The event screen is a special viewing screen that shows the last 12 events
2
recorded by the ECW500. On this
screen the events are listed in order of occurrence, with the most recent event shown in the first line of the first
page.
To display the date and time of occurrence of the events it is necessary to press the right menu key "Ti/Da", as
shown in Figure 6.5.

Through serial communication it is possible to access all the 128 available events.
