mulderm Posted August 8, 2006 Report Posted August 8, 2006 Hello, I have a PPI-network with a laptop with Microwin software and a Siemens S7-222 plc and an operator panel ESA VT150W. Problem is when I will going online with the plc I get a message: MASTERS EXIST ON THE PROFIBUSNETWORK AND THE CURRENT DEVICES DOES NOT SUPPORT MASTERS. TRY AGAIN AFTER SELECTING A MULTI-MASTER DEVICE. So I can´t go online on the network. When I will disconnected the operator panel then I can online with the plc. But this is not the way. Who can help me? Greetings, mulderm
Crossbow Posted August 9, 2006 Report Posted August 9, 2006 Check the switch settings on your cable. If you're using the new cable (part number ends in 30) you might need to change a switch setting, as this cable supports multi-master. If it's the older cable you might want to check the switches as well.
mulderm Posted August 9, 2006 Author Report Posted August 9, 2006 Crossbow, I have the PC/PPI cable 1PGES7 901-3BF20-0XA0. Only the settings for the baudrate (dipswitch 1,2,and 3), 10 or 11 bit (dipswitch 4),DTE or DCE (dipswitch 5) are available. Is this what you mean? mulderm
