Hello JD, First, I'm not sure that PAC Profibus DP expansion module will work with PAC3100. To the best of my knowledge only PAC3200 and PAC4200 haveGSD files. Now, If you mean PAC3200. The number of PACs that can be connected under the Y-Link depends on your configuration. One PAC can send more than100 measurements but the GSD file has only 61 slots and each slot can have one measurement of 4 bytes (floating point). So, one PAC can send single measurement of 4 bytes up to 61 measurements of total 244 bytes. For example if you want to read line voltage, line current, total active power and total power factor. This means 3 voltage measurements, 3 current measurements, one measurement for total active power and one for total power factor. This gives you 8 measurements which means 32 bytes that limits you toa maximum of 7 devices per Y-Link. So, you should first know what measurements you want to read in order to know total bytes of each PAC. Best regards. H-H
