OPERATION
Initial turn on
Before connecting the display to the network, we must ensure that all the connections
have been properly done and that the display is firmly in place.
Each time we connect the display to the power supply, the device perform a system test.
The test consists in displaying a sequence with all the digits showing number "8", all the digits
showing number "0" and all the decimal points are lit up. It stops with the Firmware version. At
this point any of the following three situations may occur:
a) The display receives data from the Profinet network and displays it.
b) The display does not receive data and the time without data is zero (See section
4.2.2.3). Keep showing the Firmware version.
c)
The display does not receive data and the time without data is different to zero.
After the specified time without data it displays a dash in each digit.
Programming parameters.
Before using the display, the configuration parameters must be set as required.
The parameters configuration is done through a menu that is selected by two buttons
placed at the bottom part of the display. The field that can be modified is displayed flashing.
The configuration parameters are:
1-Datatype (Float, UFloat, WORD, UWORD, ASCII)
2-Communication protocol (in case of multiprotocol equipment)
3-Time without receiving data
B, C, D, E, nr, r1, r2 y r3- Only for display with color option.
F- To exit parameter configuration.
Displays of 3 or more digits:
The 3 rightmost digits are used for the parameters programming. The third right digit can
be identified as the one which has the decimal dot activated.
The third right digit shows the parameter number and the others show the value, the
flashing digit is the one that can be modified using push buttons.
Displays of 2 digits:
In this case, the parameters programming must be done in two steps:
1- Access to the parameters using the advance button
“
”. Then, you will see two digits
with the format:
“
nº of parameter . subparameter
”
.
2- Press again the advance key to see the parameter value, and modify the flashing
digit.
