This article applies to versions 4.5.3 and later of P2 Explorer.<\/p>\n

If a datasource has been configured to allow writing to the database, right-clicking a component using that data allows you to update the tag\u2019s value at a point in time.<\/p>\n

For example, right-clicking on a Data Label displays a\u00a0Write Value<\/strong>\u00a0option, which allows you to update the value of the data label at a point in time in the database, and the data type if needed.<\/p>\n

\"\"<\/a><\/p>\n

Right-clicking on a label shows a menu containing various options.<\/em><\/p>\n

When you select Write Value\u00a0<\/strong>from the right-click menu, a box appears where you can enter the new value.<\/p>\n

\"\"<\/a><\/p>\n

The fields are as follows:<\/p>\n\n\n\n\n\n\n
Tag<\/strong><\/td>\nThe name of the tag in the database. This cannot be changed.<\/td>\n<\/tr>\n
Data Type<\/strong><\/td>\nThe data type<\/a> of the tag in the database. If the data type is known, you will have the option of changing it to Null<\/em>, if required.\u00a0This is useful in circumstances where a datum is not present at a point in time, and it is important to indicate so.
\n If the data type is detected to be Decimal,<\/em> the options will be Decimal, Integer, and Null.
\n If the data type of the value is\u00a0not\u00a0known,<\/em> it will show all data types in the drop-down list.<\/td>\n<\/tr>\n
Value<\/strong><\/td>\nType the new value of the tag here. The entry box may change depending on the data type. For example, Boolean values will show a check box, and DateTime values will allow you to use a date or time picker.\u00a0<\/td>\n<\/tr>\n
Timestamp<\/strong><\/td>\nThis is the point in time for which you want to assign the new data value. Click the calendar icon to set a date and click the clock icon to set a time. \u00a0You also have the option of using the current date and time, by clicking Use Now<\/strong>.<\/p>\n

Note<\/strong>: For some tags, it\u2019s possible to write values with a timestamp that is in the future. However Explorer cannot know in advance if the datasource will allow this.\u00a0Therefore, if you select a timestamp that\u2019s in the future, a warning is shown. You can still click OK, and if the datasource accepts the value a success message will appear, otherwise an error message will be shown.<\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

When you have finished entering your value, click OK<\/strong>.<\/p>\n
