Hello kamal; If you have set up your CM 1243-5 Profibus master module correctly in your hardware configuration, then yes, you can add Profibus/PA instruments on the Profibus network. When you work with a DP/PA coupler, there are à few points you must take into account. First, the DP/PA coupler is not configured on the Prfibus network (in hardware configuration): i is transparent. You need to isetup only the instruments, once ther gsd file has been integrated. as if they were Profibus-DP slaves. Then, the overall speed of the Profibus network must be reduced to 45,45 kB, for all slaves. https://support.industry.siemens.com/cs/ca/en/view/109771783 Next, when you configure each slave in the hardware configuration you will find out that the data exchange for each one is limited to 5 bytes: one Real (4 bytes) register for the instrument's measured value and one status byte to detail diagnostic information of the slave. Hope this helps, Daniel Chartier |
