Hello, I am having some problem with "Modbus TCP PN CPU". I use project from library "SIMATIC 300(Client)". At the beginning I have tried to connect CPU to PAC 4200 but it did not work. Now I am trying to connect to virtual modbus clients "Ananas" instaled on PG/PC without any firewall (see attachment). In both cases I have the same problem. Is it in "Control DATA DB1" Status_CONN = W#16#7002. In attachment I uploaded VAT Table with a piece of information. Sometimes after several minutes Save_status_conn has value equal 80A1 (TRCV) or W#16#A100(TCON). When I used Virtual Modbus Master (Fenix 2.5.1) it has been communicated with PAC and Ananas and it worked very well. IP CPU 192.168.1.30 IP MODBUS partner 192.168.1.70 Please help me with this case AttachmentScreens.zip (527 Downloads) |

Thanks for your advice. Now it is much better. I have the conn_established = 1 without the busy status, but data exchange is not working. What is the reason? AttachmentVAT_client.zip (541 Downloads) |
