Usage

First check that your opc-server is available by running this command:

> osl154da list-servers

The name of your server should appear in this list. This is the name to be used in the next step.

Create some initial BMP-data for your sign. You can use the discover function:

> osl154da discover-sign SERVER.1

Or add it manually:

# NB! Make sure server, tag, width and height match your server and sign
> osl154da add-sign sign1 -server SERVER.1 -tag SSA1_SIGN1 -width 304 -height 104

This command will create a directory signs/default:

/signs
    /default
        /sign.json
        /1.bmp
        /2.bmp
        /3.bmp
        /4.bmp

BMP-file can be duplicated and edited to make different test images. sign.json can also be edited to adjust opc-tag names.

NB! If you run the add-sign or discover-sign command again all changes will be overwritten.

Read the values currently on the sign:

> osl154da read

Send a rgb-on command to the sign:

> osl154da rgb-on -image 1.bmp

Image 1.bmp will now be loaded in IMAGE_TOSET. VALUE is set to 9999 and after a short delay the COMMAND is set to RGB-ON.
