MEMORY VARIABLES The device provides 35 positions to store texts, numerical values or combinations of elements to be evaluated. The rules associated with the memory variables are stored in |
|
The VALUE field is periodically updated by the device, so it must not be used directly to store data that must always be entered in the EXPRESSION field. Contents of the memory variables is kept even when the device is turned off. |
|
We can enter a number or a text in the EXPRESSION field, this static content (constant) will be transferred identical in the VALUE field. We can enter an expression to be processed, this dynamic content (variable) will be processed every 60 seconds and the result transferred to the VALUE field. For numerical values up to 2 decimals are accepted. If the entered value is an integer the result will be rendered as an integer. If the entered value has a point as a decimal separator, the result will include up to 2 decimals. To embed the value of a TAG in the EXPRESSION field, enter the identifier preceded by the dollar sign $. Here are some examples of static content and dynamic content with the related usable operators. |
