M.Dehshat Posts: 7 Rating: (0)	I have a project that containone S7-400 CPU 414-3DP with one CP441-2 modbus slave and 6 DP slaves with ET200m,IM153-2 that each slave have a CP341 modbus master and each modbus master have 4 modbus slave (ALSTOM M230 power measuring device). CP441-2 on the main rack is working as a slave and the master is a third party DCS. My problem is MODBUS communication.I was read all the pdf documents and check the sample program of siemens but somthing is not clear yet for me . I think if i have a sample program of modbus communication (Modbus master rs485 with minimum 2 slaves) i can solve my problem. Can any body kindly give me a sample program. thanks
