Hello
We are experiencing a strange problem with our little network of two S7-315-2DP CPU's. They are connected on a fiber optic Profibus DP network for data presentation on Siemens OP7 and TP27 panels, and for data exchange between CPU's.
We want to be able to connect remotely to both CPU's via telephone/modem, so we have connected one CPU to the modem with a TS adapter to the Profibus interface.
The data exchange between the CPU's is working well, but we cannot access the remote CPU for programming. The strange thing is that if we connect the two CPU's with standard profibus cable, there are no problems with programming.
Anyone out there who know about this kind of problem?
