In the functional blocks, it is also possible to enter literal values as shown in the figure that follows.
Figure 1: Example of Program
In this example, the PT input of the TON block was configured with the value 1000, which is a literal.
In order to enter literals, the following conventions must be used:
| • | Whole number has no decimal point. |
| o | E.g.: 12, 1000, 1555 |
| • | Real numbers with floating point must necessarily have point. |
| o | E.g.: 1.5, 2.25, 3.0 |
| • | Numbers represented in hexadecimal must necessarily define the data type. |
| o | E.g.: BYTE#16#7F, WORD#16#3CF0, DWORD#16#00FF0088 |
| • | Numbers represented in binary must necessarily define the data type. |
| o | E.g.: BYTE#2#1010_0000, WORD#2#0111_0000_0000_0001 |
|
ATTENTION! In some blocks, for data verification and consistency reasons, it will be necessary to define the data type of the literal through specific notation that will contain the following options: BOOL#, BYTE#, INT#, UINT#, DINT#, UDINT#, WORD#, DWORD# and REAL#. Example: WORD#17321 |
