Hello Tekabi; "The output parameters of STATUS_0A and STATUS_1A equals with 16#A090" A090(hex) is the warning code signaling that you are working with a demo version of the Modbus TCP blocks, that is, you have not purchased and properly installed the Modbus TCP license yet. In the pdf document modbustcppncpu_en.pdf from this FAQ, you will find this information: "In case of a missing or incorrect registration key, the Modbus/TCP communication is processed but W#16#A090 "No valid license available" is always displayed at the STATUS_MODBUS output. The output bit LICENSED is FALSE." https://support.industry.siemens.com/cs/ww/en/view/22660304 If you look at your CPU diagnostic buffer, it should contain the same warning. That is the way Siemens has decidedto protect its Modbus TCP drivers from programmers who do not want to pusrchase tthe license, and are content with the demo version. The programers' clients do not like red SF LEDs on the CPU and overflowing diagnostic buffers showing w#16#0A90... The status information showing w#16#A090 will disapear once the license is installed, and will be replaced qith the actual connection status for the driver. Hope this helps, |
