calvinli1681 Posted September 14, 2005 Report Posted September 14, 2005 Dear Siemens experts, I am a very new to the S7-400 PLC system. I am using a S7-400 414-3 CPU, what I am try to achive is to send some data or constant or integer, via the PLC Profibus though a gateway (AnyBus Gateway) convert the Profibus protocol to Modbus protocol. On the Modbus side I have a computer simulator as a Modbus slave to see what every has been send over. At the moment I can only get the network going between Gateway and the PLC though the Profibus. I don't know is that is a function block has been done for this task. Or I can download it from somewhere. I have try to write in SCL a new block to that function, but it is a bit hard for a newbe. Please give some help and thanks for all the advise. Quote
