S7-SoftPLC:Configuring CP340/440 emulation in PLC43.INI
From IBHsoftec Wiki English
The basic settings of the CP340/440 emulation are conducted here. S7-SoftPLC expects a section named [CPx40_SerialPorts], in which the following keys are being used:
General part:
| Key name | *Default value, Value range | Description |
|---|---|---|
| ReceiveFB_Number | *9, 1 .. 16383 | Number of receive block |
| SendFB_Number | *10, 1 .. 16383 | Number of send block |
| CPU_Stop | *0, 0 .. 2 | 0=continue, 1=pause, 2=close port |
| NoOfPorts | *0, 0 .. 64 | Number of serial ports |
Port specific part:
The described parameters concern the specific port settings and are in given form: "P##Parametername", where "##" represents a two digit placeholder for the consecutively numbered portnumber and "Parametername" represents the Keyname
