Hello everybody! Firstly, happy new year to all. Please: I'm trying to establish the communication using ISO-on-TCP between two S7-300 CPUs. I've tried to follow the instructions and sample code described and available on Entry ID 29737976 but it's not working. Could someone help me checking what could be wrong? I'm attaching the archived backup for Step7 5.7. I also tried to set /unset TSAP Extension, change the data length and etc... Tried to use the Open Communication Wizard version 2.3 Thank you all so much! Best Regards AttachmentZ_iot_xc.zip (597 Downloads) |

Dear Ivan, For sure! I attached a Word file with print screens of my hardware configuration and Open Communication Wizard screens. My architecture and hardware configuration is: CPU 1 - named Central => IP 192.168.0.1 / 24 Model: 314C-2PN/DP CPU 2 - named DM => IP 192.168.0.2 / 24 Model: 315-2PN/DP On both sides we have 2 DB for send/receive data. DB100 to send data and DB 200 to receive data. We are trying to transfer 100 bytes between both sides. When we download the software to controllers, on Module Information > Communications of 314C-2PN/DP we can see active Open Communication (the counter shows 0 ). I can see that the communication block is firing on both sides. On Central CPU and on DM CPU: TCON Status shows 16#7000 TSEND Status shows W#16#0000 TRCV Status shows W#16#0000 TDISCON Status shows W#16#0000

Hello esantos; To add to Ivan's memories, here is a document from Siemens detailing the programming blocks required for ISO-on-TCP exchanges betweens S7-300 CPUs, usin their integrated Profibnet ports:
