Translation from the Portuguese text:
Olá Natan ; O fórum da Siemens reúne participantes de todo o mundo, portanto, para facilitar nosso intercâmbio, selecionamos o inglês como língua comum. Por favor, escreva-nos em inglês na sua próxima visita. Hello Natan; The Siemens forum brings together participants from all over the world, so to facilitate our exchanges, we selected English as a common language. Please write to us in English on your next visit. Your model of CPU hss only one integrated interface, it is dedicated to the MPI protocol (,RS-485) and can be used for programming the CPU and MPI exchanges only. To communicate ovrr Modbus you need an additional communication processor. The following discussion contains the basic information on Modbus RTU (serial) with a S7-300 CPU. It requires a CP 341, which can work either on RS-232, or RS-485, and a loadable driver Modbus Master ir Modbus Slave. Give us more details on the project and we can provide more detailed information. https://support.industry.siemens.com/tf//ww/en/posts/s7-300-modbus-rtu/212830/?page=0&pageSize=10 Hope this helps, |
