SUMMARY
The SoftPLC7_SYF.dll replaces modules operating internally of a PLC.CONTENTS
Introduction
The internally used FCs, FBs, SFCs, SFBs are replaced by functions out of the SoftPLC7_SYF. The information for redirecting is taken from the SoftPLC7.ini file. For any missing entry a default is created. If only standard functions are used no entries need to be made.

INI-FILES
SoftPLC7.ini
Section [HLL-Functions]
| Entry | Type | Description / Example | Default |
|---|---|---|---|
| (FB |FC |SFB |SFC )<num> | string |
Defines the DLL-Function that replaces the Program-Module
with the following syntax: <dll, function>
Example
FC13=MyDll, MyFunction [HLL-Function] FB15=SoftPlc7_SYF, NOP FC16=SoftPlc7_SYF,S7TRUE FC17=SoftPlc7_SYF,S7FALSENOP The execution of a FB or FC may be omitted by defining ‘NOP’ (no operation) for that function; in such a case only the BIE-Flag is set. TRUE/FALSE The defined function is replaced and the constant value TRUE or FALSE is returned instead and the BIE-Flag set. (It may be used to distinguish between a Hard= and a SoftPLC7) |
