Hello Mushriq if I understand you correctly you only have a handlful of DP Slaves that you want to connect to the CPU, correct? If that's the case (or even if it is a few dozen DP Slaves) I wouldn't worry too much as the CPU can easily handle it. The absolute I/O limits of the 319-3 PN/DPcan be found in the technical spec (see HERE for more) and are: - 8 Kbytes of I/O's address area in general. - 124 DP Slaves per DP Master port (of which your CPU has two and you can add more via CP342-5 if need be). - 244 bytes of cyclic I/O data per DP Slave (this is a Profibus standard value and applies for any DP slave). I hope this helps |
Cheers |

In additional: Without repeaters you can connect max 32 node (slave). |

Hello Hazem, Check specification of your CPU if more than 32 slaves. |
