The description of the device series 0BA3 and earlier is found below.

Short description

This function displays message texts and parameters of other blocks on the LOGO! Display when LOGO! is in RUN mode.

Note: The LOGO! 0BA6 device series supports many new message text features that LOGO! 0BA5 devices and earlier did not support. You can choose, however, whether to use LOGO! 0BA6 message text functions blocks with the new features or LOGO! 0BA5 message text function blocks in your circuit program. This selection is on the File -> Message Text Settings dialog, along with other global settings. You can also use the button at the bottom of the LOGO! 0BA5 message dialog to change your message text functions to the LOGO! 0BA6 style with the new features. You cannot mix and match LOGO! 0BA5 message text function blocks and LOGO! 0BA6 message text function blocks in your circuit program.

 

Connection

Description

Input En

A 0 to 1 transition at En (Enable) triggers the output of the message text.

Input P

P is the priority of the message text.

0 is the lowest, 30 the highest priority.

Ack: Acknowledgement of the message text

Parameter

Text: Input of the message text

Par: Parameter or actual value of another, already configured function (see "Visible parameters or actual values")

Time: Shows the continuously updated time-of-day

Date: Shows the continuously updated date

EnTime:  Shows the time of the 0 to 1 transition

EnDate:  Shows the 0 to 1 transition of the date

Output Q

Q remains set as long as the message text is queued.

Description of the function

With a 0 to 1 transition of the signal at input En, the display outputs your configured message text (actual value, text, TOD, date) in RUN mode.

Acknowledgement disabled (Ack = Off):

The message text is hidden with a 0 to 1 signal transition at input En.

Acknowledgement enabled (Ack = On):

After input En is reset to 0, the message text is displayed until acknowledged by pressing the OK button. The message text cannot be acknowledged as long as input En is high.

If several message text functions were triggered with En=1, the message with the highest priority (0 = lowest, 30 = highest) is displayed. This also implies that a new message text is only displayed if its priority is higher than that of previously enabled message texts.

After a message text is disabled or acknowledged, the function automatically shows the previously active message text that takes the highest priority.

You can change between the display in RUN mode and the message texts by means of the image\logo_up_sn.gif and image\logo_down_sn.gif buttons.

Restrictions

Up to 10 message text functions are available.

"Enable new style message and setting"

Button to switch to LOGO! 0BA6 style message texts with new features. You must then complete the File -> Message Text Settings dialog to configure settings for LOGO! 0BA6 style message texts. All message texts will be in the LOGO! 0BA6 style after this selection.

To arrange the message text

  1. From the "Blocks" area, select the block whose parameters you want to output.

  2. Drag and drop the parameters required from the "Block parameters" to the "Messages" area. You may also use the "Insert" button to do so.

  3. In the "Messages" area, you can add parameter data as required.

Display of a configured message text in RUN mode

 

Connection

Description

Input En

The message text is output with a 0 to 1 transition at input En (Enable).

Parameter P

P is the priority of the message text.

0 is the lowest, 9 the highest priority.

Parameter

Par: Parameter or actual value of another, already programmed function (see "Displayable parameters or actual values")

Output Q

Q remains set as long as the message text is queued.

Description of the function

In RUN mode, a 0 to 1 transition of the signal at input En triggers the output of your configured message text on the display. The message text is closed after a 1 to 0 transition at input En and if the acknowledgment attribute is not set. If the acknowledgment attribute is set, the message text is not closed until input En=0 and the message is acknowledged at the LOGO! with OK. The status at output Q remains 1 as long as the message text is displayed.

Of several message text functions triggered with En=1, the one with the highest priority is displayed. Low-priority messages can also by displayed by pressing the image\logo_down_sn.gif button on the LOGO!.

You can switch between the standard display and the message text display by means of the LOGO! buttons image\logo_up_sn.gif and image\logo_down_sn.gif.

Restrictions

Up to five message text functions are available.

Particular characteristics to be noted when configuring

The message text can be configured in the block properties dialog. You can enter up to four lines for each message text (the text display of the LOGO! has four rows) and set the priority. You can move to the next line using the cursor keys or the mouse. Hit the [ENTER] key to confirm all your entries in the block properties dialog and to close the dialog.

You may also enter the actual values of other blocks in the text lines. To do so, select the relevant block from the Block dialog. A Parameter dialog opens to display a list of all parameters available for the selected block. The block parameter you select in this dialog is written to the selected text line. The actual parameter value is now included when you call the message text.

 

Set the "Acknowledge message" attribute to specify whether a message is be acknowledged before it is closed.
