5.8 System libraries from the SysLibs23 range

Libraries that have been transmitted (due to reasons of compatibility) from the »PLC Designer« V2

to version 3, may respond differently than under V2.

• Example: SysFileOpen with Mode = a (append) does not create a file under 3.x (unless availab-

le). The »PLC Designer« V2.3 creates this file.

• Remedy: The use of the functions must be adapted manually (after the conversion) on an in-

dividual basis.

 Note!

Import of variables of a »PLC Designer« V2.3 project into the »PLC Designer« V3

• The declarations of the Retain variables remain stored (and have an unchanged same

effect).

• The declarations of persistent variables must be revised and re-created. Create an

own global variable in the »PLC Designer« V3!

•An "AT Declaration" must not

be used in combination with VAR RETAIN or VAR

PERSISTENT!

• The size of the provided memory area in the »PLC Designer« V3 depends on the target

system. If required, adapt the number and value of the retain variables!
