Good afternoon,
Sorry for the rather brief question this morning with respect to the profibus problem. I am conducting a technical thesis using an OP37 along with an S7/400 Seimens PLC. The controller is working properly and is ready to run, keep in mind that I am using a CPU315-2DP. The OP37 is an add-on and we want to establish communication between the PLC and the HMI (pro-tool-pro). I have tried different methods to place the op37 on the profibus, however all attempts have been unsuccesful. In addition, I examined the rear of the OP37 today and discovered switches on the back; what is the relavance of these switches when connecting the OP37 to the profibus and what should they be set to. Thanks in advance, Jeff burke
