T-communication blocks and PLCSIM

Dear All,

I want to simulate communication between two ( CPU 319-3 PN/DP ) by using ( TCOMMUNICATION BLOCKS (T-CON,T-RCV,T-SEND) and ( PLCSIM V5.4_SP5_UPd2)

I have used OPEN COMMUNICATION  WIZARD TOOL  to get connection parameters UDT.

and after download program on both CPUs I found output ( T-CON.DONE = true) even I removed second plcsim ,even I did not trigger (T-CON.REQ).

so I think i have something wrong.

Thanks in advance

Hi Mop,

1st CPU ( CPU 319-3 PN/DP ) IP-address 192.168.1.10

2nd CPU ( CPU 319-3 PN/DP ) IP-address 192.168.1.20

Connection Type TCP/native

My questions:

1- why output (TCON.DONE = true ) without request connection. ( another words how can i check connection established or not ).

Thanks and sorry for confusing.

Thank you

New question published by moelsayed is split to a separate thread with the subject Does PLCSIM support only S7-CONNECTION blocks and does not support OPEN COMMUNICATION BLOCKS?.
