A Clear Text Display (OPM2) is required to set theCOMBIMASTER parameters prior to connecting thePROFIBUS module.2. The PROFIBUS Module may only be connected ordisconnected from the drive when the drive is poweredoff.3. The PROFIBUS module must only be connected to thedrive with the cable supplied for the purpose.4. The PROFIBUS module cannot be used simultaneouslywith the Clear Text Display module.The data structure for communication over PROFIBUS-DPcan be either PPO type 1 or PPO type 3 as specified inVDI/VDE 3689. This means in practice that process data(control words, setpoint in the transmitted telegram and statuswords, actual values in the received telegram) is always sent.Parameter data exchange may, however, be blocked if bus orPLC memory space is at a premium. The data structure andthus the PPO type is normally specified by the bus master. Ifno PPO type is specified (e.g. if a combined DP/FMS busmaster is used), then the default PPO type is type 1(parameter data enabled).Parameter write access over the serial link can be enabled orblocked as required. Parameter read access is permanentlyenabled, allowing continuous read out of drive data,diagnostics, fault messages etc. A visualisation system canthus be realised with minimal effort.The PROFIBUS cable is connected to the 5-way miniaturecircular socket on the side of the PROFIBUS Module, via aspecial ‘T’ connector which fits to the edge of the module.Siemens DA 64 – 1998/99 (04/99) 8/31
