What's in this

Section?

This section describes the Data to send parameter.

It is intended for application developers who want to install built-in DOP functions without using the input help screens.

This section contains the following topics:

The table below shows the significance of the different words which constitute the following parameter: Data to send (47 words maximum).

contains a marker of value 16#CC17, contains value 0 contains the length in bytes and the zone of the following words, contain the message text to send, this being the characters that are underlined representing the characters expected during the display of a variable. The maximum length of this text is 40 characters.

If the text is composed of an odd number of characters, the last byte is worth 0, if the text is of even length and if it is less than 39 characters, the last byte must contain the value 0, contains the line number where the message must be displayed, contains the column number where the start of the message must be displayed,

This two word zone (four characters) contains the message characteristics and is structured as follows:

Character 1 This character (in capitals) corresponds to a video attribute: z z z z

B = blinking,

R = reverse video,

A = blinking and reverse video,

N = no attribute

Character 2

Characters 3 and

This character (in capitals) corresponds to the character font size: z S = normal size, z D = double width or height corresponds to the printing option: z Y followed by a space = yes, z N followed by a space = no.

If you do not want to display a variable, the following word must be at 0 (in this instance, following parameters is ignored), otherwise the following parameters must be added: contains the position of the variable to display, counted in number of characters in relation to the start of the message.

contains the number of characters to display for the variable.

Configuring command keys: ASSIGN_KEYS function

Introduction It is possible to set the configuration of the command keys (bit associated or not, key operating mode, assignment by CCX17…) and send it using internal words (%MWi) as intermediaries to display them on a CCX17 console screen. This is the role of the

ASSIGN_KEYS function.

Meaning Word number

The table below shows the significance of the different words which constitute the following parameter: Data to send (12 words).

If a PLC carries out the assignment… this word contains the list of keys to configure. Each command key is coded on a bit (0: non configured, 1: configured): z bit i (i = 1 to 8) command key no. 1.

the following two words indicate the operating mode of each of the command keys. Each key is coded by two bits z 00: Reset, z 01: functioning mode on edge, z z

10: toggle functioning mode,

11: no action.

Bits 2j,2j+1 = command key i+1 (i = 0 to 11) the following eight words contain, accordingly: z a value –1 when the command keys are not affected, z the index of the internal bits affected by the command keys

Word i = command key i (i = 1 to 8)

If a CCX 17 carries out the assignment… this word contains 16#F000 the values of the following ten words are indifferent and will be ignored by the CCX 17 console.
