Hello qwemx; First, you must know how to (minimally) choose parameters on the drive enabling Profibus-DP comms. and you mut learn how to read and write at least the control/status word and the speed reference/actual value. The first document will show you how rto do both (note that the basis address for the CB^P2 card in Step 7 is 256 in this example, adjust for the address given to this Masterdrive in the harware configuration. Connection of Masterdrives to Profibus-DP. These documents show wthat others are requesting the same type of helps as you are, and that once you are connected to the PLC the answers should be found in the Compendium (the last link). Profibus Communication with masterdrive - Entries - Forum Vector Control - Industry Support Siemens Hope this helps, Daniel Chartier |

In the picture attached i have input and output addresses for the PKW area which is i believe input from 256 to 263 , output also from the same 256 to 263 PZD area input starts from 280 to 291 and output from 276 to 287 so i have to use these addresses when writing data(set-points , control word ) to slave and vice versa |
With kind regards... |

Hello qwemx; True, the PZD addresses start at 280,for inputs and at 276 for outputs. Which means that in your program you must address them as PIW280 (for the Status word read) and PQW276 (for the control word write); The speed actual value is in PIW282, the Speed reference is in PQW278; and so forth. By the way, I always prefer having the input and output start addresses equal, it is more symetric; you can change these values to make the stsrt address of boh inputs and outouts to 280, for example. Drive Monitor should make your configuration and setting of parameters) of the drive easier. Here are some links: Download : DriveMonitor Version V5.5 SP2 for SIMOVERT MASTERDRIVES, MICROMASTER and SIMOREG. Hope this helps, Daniel Chartier |

Hi Daniel , so the second word of the Incoming PZD is the actual speed , i think this is the default settings and we can change which word carries which value ,for example we can tie the actual speed to the third word instead of the second ? is this correct the Simovert Drive I have also has two CBP2 cards one in the upper slot and one in the lower slot . |
