Hello for all.

I tried use T_CON, SEND from real PLC1511 to HyperTerminal on my PC. I used IP PLC 10.1.0.170  port 2000  and 10.1.0.100 PC. But i had no results, i always had status of connection 7002. 

On PC i swithed off  Firewall and antivirus during my tests. Is it neccessary to make also come changes on PC side for testing?

What could be wrong?  It is simple task to make communication with printer, only 1 block (TCON) i must use , but i can't make it work.

Split from TCON TCP Port not available.

Hello,

the PC establish the connection to PLC in Your case. That's right?

On PC, switch off firewall, antivirus while testing.

Note, that status on TSEND_C is only available for one cycle. So please save status-value in separate variable. Only in this case, you find out the "real" status value.

Do you try to sniffer network connection between PC and PLC? Just to know, if the packets arrive PLC or perhaps nothing is send to PLC.

 Please try these points and publish a screenshot of your genereated DB on PLC ...Just to see, if everything is configured right.
