IBH Softec SoftPLC not active yet

Trying to get into contact with the IBH SoftPLC by the DLL ‘plc32.dll’, an error has occured.

Therefore two reasons are possible:

1.) You have not started the IBH SoftPLC / simulator yet. Do it now and after that select PLC|External PLC again.

2.) If the IBH SoftPLC is already active you will have more than one copy of ‘plc32.dll’ on your computer. It is important that TrySim uses exactly the same copy of the dll as the SoftPLC! The path you can enter in PLC|ExternalPLC|Interface-parameter, points at one of the copies, which is not used by the IBH SoftPLC. (Pay attention to the selection ‘IBH SoftPLC’ before you select ‘interface-parameter’.)

Using the Windows function Start|Search you can search for ‘plc32.dll’. If the worst comes to the worst you will have to try all the data which are found there.

If you start the SoftPLC by the network you will have to put the complete computer name (‘\\ComputerX\C\.....’) in front of the path. Or you connect the network with a disk drive letter over the button ‘network’.

If you use the demo version of the S5-simulator the dll will be named ‘plc32dem.dll’.
