Ack: Acknowledgement of the message text

Parameter

Text: Input of the message text

Par: Parameter or actual value of another, already configured , which can be displayed numerically or as a bar graph (see "Visible parameters or actual values")

Time: Shows the continuously updated time-of-day

Date: Shows the continuously updated date

EnTime: Display of the time of the 0 to 1 transition of the signal at input En

EnDate: Display of the date of the 0 to 1 transition of the signal at input En

  • hours : minutes : seconds

  • hours : minutes

  • hours

(for example, "01: 20 : 15 .15")

Settings

In addition to the function block inputs and the parameters of the message text, the following settings provide additional control over the display of message texts:

Particular characteristics to be noted when configuring

Block name area

Here you can provide a name for the block

Settings area

Here you can configure the following settings:·

  • Priority of the message text

  • Acknowledge Message check box: if set requires a message to be acknowledged in order to be closed

  • Character set selection for the message text

Block area

Here is where you select blocks from all of the blocks in the circuit program. You can subsequently choose parameters from these blocks to display in the message text.

Tick area

Here you define the tick parameters for the message text:

  • Character by Character tick format

  • Line by Line tick format

  • Tick enabled checkbox for each display line

Message destination area

Here you choose whether the target destination for the message is the LOGO! onboard display, the LOGO! TDE, or both. If you select the Web server as a destination, you can display LOGO! message texts through the Web server.

Show message information in details

Here you can chose to show the message texts in detail. By default, the message text only show the status of priority, acknowledge message, and character sets. By selecting this function, you can see the ticker setting, message text setting, and message texts in the diagram editor.

Block parameters area

Here you can select the parameters to be displayed in the message text from the block that is selected in the Blocks area.

Insert Parameter button

This button is for inserting a selected block parameter into the message text.

Message area

Here you arrange the message text. The information that you enter in this area corresponds to what is to be displayed on the LOGO! onboard display or LOGO! TDE.

Above this area are additional buttons:

Delete button: for deleting entries from the message area

Special characters button: for inserting special characters into the message area

Bar Graph button: for placing a horizontal or vertical bar graph into the message area

AI button: for placing an analog input value into the message area

ON/OFF button: for specifying a digital value to be represented by one of two strings corresponding to the 0 state and 1 state, for example "OFF" and "ON".

Symbol button: for opening the virtual keyboard panel. You can insert characters of current character set.

Scale time button: for referencing an actual value and showing it in a specified time base format.

Edit manually button: for using the static editor to add, move, or delete message text elements without changing the position of any other elements.

Note: For LOGO!Soft Comfort V8.3 and later versions, copying and pasting parameters of message texts in the same circuit diagram are supported.

Below this area is one additional button:

Overwrite:

  • If you double click the Overwrite button, this button turns grey, you move the cursor over an existing parameter and enter a new parameter, the new parameter is inserted before the existing parameter in the message area.

  • If you don't double click the Overwrite button, move the cursor over an existing parameter and enter a new parameter, the existing parameter is replaced by the new parameter.

To arrange the message text

The LOGO! 0BA8 and later version devices support six-line message text display. The message area shows a grid of six lines and character positions.

If you choose the LOGO! onboard display as the target destination for the message, the message text area is 32 characters wide for Western European character sets or 16 characters wide for Asian character sets. If you choose the LOGO! TDE as the target destination for the message, the message text area is 40 characters wide for Western European character sets or 20 characters wide for Asian character sets. Either way, the character width of each line is double that of the LOGO! onboard display or LOGO! TDE. If you choose both as the target destination, the message text area is still 32 characters wide for Western European character sets or 16 characters wide for Asian character sets. In this case, there is a red vertical line in the message text area indicating the boundary of the LOGO! TDE display. If you also select the Web server as a destination, the message text displays through the Web server in the same way as on the LOGO! onboard display.

Message lines that are longer than the width of the actual display can be set to "tick". In the message area, LOGO!Soft Comfort indicates the region corresponding to the visible area of the LOGO! onboard display or LOGO! TD in green, and the region that can only be shown by using the message ticking feature in blue.

To configure the content of a message text, follow these steps:

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

  2. Drag and drop the parameters required from the "Parameter" area to the "Message Text" area. You can also use the "Insert Parameter" button to insert a parameter value.

  3. In the "Message Text" area, you can add parameter data, time or date values from the block parameter area as required and enter text. To enter text, select the character set for the message text, and then type. You can also use the buttons above the message text area to add special characters, bar graphs, analog input values, and names for digital I/O states.

New special characters

There are five new special characters ( ) available for the message text display on LOGO! 0BA8 devices or LOGO! TDE. With these special characters, you can create large texts for message display.

You can start or stop messages online by clicking the toggle button, and the messages are displayed as follows:

During a message online test, you cannot use LOGO!Soft Comfort to edit message text parameters, change the character set, acknowledge a message text, or shift a message text. You can, however, use the "Go to block" button.
