New system release PSS 4000 1.24
- New data types FIXED and LFIXED
The data types FIXED (fixed point number with 6 decimal places) and LFIXED (fixed point number with 11 decimal places) are now available for the controller PSSu H PLC2 FS SN SD(-T). As a result, more complex arithmetic calculations are now possible.
- Nesting of data types up to a depth of 16
The declaration of data types in the user program is now possible with a nesting depth of up to 16. Each dimension of an array variable (ARRAY) is also added to the nesting depth. That enables you to structure the project better.
- Increased security through the function "Link device projects to devices"
Previously, devices with a device key have also executed projects that had no project key. Now it can be configured that a device with a device key only executes projects with the appropriate project key. This guarantees that only projects that are actually assigned to the device can be executed on the device.
- Support of Windows 11
The use of PAS4000 under Windows 11 is now supported.
