I have a single infeed module that feeds all the control units. I would like to pass the enable signal from the infeed module to the control units by way of BICO parameter instead of by DI/DO. I was looking at parameters 8510 and 8511, but don't know to transfer them from control unit to control unit. I have been able to configure the telegram packet and address list to read the parameters but have not figured out how to write individual bits. Any help towards programming references would be appreciated. Chris

You can also not use the slave-to-slave communictaion because you have PN Devices and no DP Devices. Sop the only thing is to transfer the signal for Infeed ready via the IO-Controller (Simotion D) to the 4 CU320-2 PN (use additional Telegram or extened telegram). But this is not a good solution, here you should use the cable wiring. Regards Christoph
