Hello, You can use STEP7 V5.5 or TIA (if your CPU and CP are young enough to be listed in TIA). From the FAQ you can download the demo versions and the documentation. |
Best regards |

Hello massoud; To clarify the basic question you have: - Modbus TCP is an industrial communication protocol that uses Ethernet TCP/IP to transport Modbus frames between controllers and automation equipment; it is part of the Modbus series of protocols, which includes Modbus RTU, Modbus ASCII... Simply Modbus - About Modbus TCP - Open Modbus/TCP is a Siemens collection of licensed blocks that will load and enable Modbus TCP functions on S7-300 or S7-400 CPUs and CPs: Open MODBUS/TCP for SIMATIC systems - Siemens S7-1200 and S7-1500 PLCs do not require these blocks, as they already have integrated instructions for Modbus TCP. Hope this helps, Daniel Chartier |
