View source for S7-SoftPLC:Configuring CP340/440 emulation in PLC43.INI

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: ====

{| class="wikitable"
|-
! Key name !! *Default value, Value range !! Description
|-
|style="width:12em"| ReceiveFB_Number ||style="width:12em"| *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: &quot;P##Parametername&quot;, where &quot;##&quot; represents a two digit placeholder for the consecutively numbered portnumber and &quot;Parametername&quot; represents the Keyname
