I wish to communicate between PLCs using TRCV_C and TSEND_C by the CP1243-1 (6GK7243-1BX30-0XE0 V3.1.40), but I can't make it work. I attach a picture of an sample project that works well, I also attach a picture with the same project but with a link between the two CP1243-1, but this don't work. Can someone help me?

In this setting, I confirmed is set to the HW-ID of the CP. Thank you for trying, do you have any other guess?

The first was the "tcp connection monitoring time" at 180s, which means that after connection is restore, it takes 180s to start to data exchange. In the project, was use the 6GK7243-1JX30-0XE0 V1.1, but this version of the firmware does not support the T-Blocks. Un firmware upgrade is required.
