51 MB
Service Pack 3 (SP3) for S7-PLCSIM V5.4 provides the following new functions:
-Multiple startability (multi-instance capability) and communication support between the simulated CPUs (simulation instance) !!!
-Optimized download by omitting the Node Browser
-Support of an additional PG/PC interface: PCinternal (local)
-Optimization of the communication between S7-PLCSIM and WinCC / WinCC flexible
-Indication of all CPU access addresses in the status line
-Multiple startability (multi-instance capability) and communication support between the simulated CPUs (simulation instance) !!!

Can you send me (share to us ) sample program in STEP7 using 2 CPU (with command Send/Recv with CP343 ) like above ??,
I want to try with S7 PLCSIM V5.4 SP3

Thanks alot

Multiinstance PLCSIM is interesting indeed.
Another great enhancement will be a connectivity with third party OPC server.
That's will make plcsim a complete test environment.
Or it can connect already?

See Readme.rtf

7.3.5 Multiple startability of S7-PLCSIM V5.4 incl. SP3 with communication support between the CPUs
The new function enables concurrent simulation of several CPUs. These different CPUs can communicate with each other if an appropriate hardware configuration was downloaded previously. This requires unique addresses of the CPUs in the same subnet.
Communication between the CPUs supports the following communication blocks:
• SFB8 “USEND”,
• SFB9 “URCV”,
• SFB12 “BSEND”
• SFB13 “BRCV”
• SFB15 “PUT”
• SFB14 “GET”
• SFB19 “START”
• SFB 20 “STOP”
• SFB 22 “STATUS”
• SFB 23 “USTATUS”

Try example http://support.automation.siemens.com/W ... en/1819293
Change data inside DB200 for view result DB201

how communication support between the simulated CPUs (simulation instance) ?

see Readme 7.2
Upload to Active interface BLACK/BLACK
BLACK/Gray is inactive
for activate need Select instance and select interface in Toolbar

After uploading all interfaces will have the personal addresses

Does not work with IM151-7 and CPU 314C-2DP.

I have searched this until now. I haven't tried yet. But, this make very happy me.
thank you all, for your helps.

this system worked perfectly.

written datas to DB201 in PLC2 are read in DB200 of PLC1. They are moved By SFB14.

written datas to DB201 in PLC1 are written to DB200 of PLC2. they are written by SFB15.

I understand them now. Ididn't use to know before.

Thank you all..
