Hello Matrex; The CB15 is one of the first Profibus interface modules for MM4 drives, and it has some limitations that you might have to take into account. Have the manual handy for thisL https://support.industry.siemens.com/cs/.../CB15_155_Operating_Instruction_76.pdf As you can see from the screenshot below, only PPO1 and PPO3 are supported by the CB15, which means that the only words you can transport via PZD area words are the Control word (for start/stop...) and the speed reference word. You cannot add the amps, for example. PPO1 also lets you to use the PKW area, which allows the read/write of one of the drive parameters at a time. Once you have inserted the gsd file in the profibus configurator, you should find the CB15 as part of the "Other slaves" section of the Profibus catalog. Click and drag a CB15 to the Profibus network line in the Profibus configurator central screen, so it opens a configuration dialog. This will allow you to select PPO3 for example (if you only want to control the drive,, not read parameters), and the I and Q addresses reserved for this instance of a CB15 will be allocated; if you are using more than one drive with a CB15, simply drag more instances to the Profibus network line, each will receive new and unique I/O addresses. Once you see these addresses, the following FAQ from Siemens Support may help you along: MICROMASTER 4 (MM4): Setting up an MM4 with a Profibus module https://support.industry.siemens.com/cs/ww/en/view/8894363 Hope this helps, Daniel Chartier |
