    7.2.1 SDO Introduction 7.2.1.1 Upload SDO Protocol Initiate SDO Upload Protocol Before transferring the SDO segments, the client and server need to communicate with each other by using the initiate SDO upload protocol. Via the initiate SDO upload protocol, the SDO client will inform the SDO server what object the SDO client wants to request.
  • Page 43 0: normal transfer 1: expedited transfer If the e=1, it means that the data of the object are equal or less than 4 bytes, and only initiate SDO upload protocol is needed. If e=0, the upload SDO segment protocol is necessary. s: size indicator 0: Data set size is not indicated.

  • Page 66 7.2.5.2 Manufacturer Specific Profile Area In the following table, there is information about some special functions for the PM-4324-CPS. The index from 0x3200 to 0x3209 records the power meter measurement parameters. The number of these entries will be automatically updated when the PM-4324-CPS boot up.

  • Page 72 Q1. Can we use the other 5A CT’s (like 600/5) to directly connect to the input current terminals of PM-4324 series? No, because the input current is only mA size on PM-4324 series，definitely not to directly use other 5A CT’s to connect and apply （like100/5…） ，It could causes the fetal damages.
  • Page 73 (4) Confirm the RS-485 connection, make sure the D+/D- is right. (5) Confirm the RS-485 master have to provide the bias for PM-4324 series. Otherwise, the tM-SG4 or SG-785 should be added to provide the bias. All ICP DAS controllers and converters provide the bias.
  • Page 74 The CT of PM-4324 maximum range is 400A. If the target is more than 400A, we suggest the solution as follow. For example the target is to measure maximum 800A current. We can measure big CT output and set a CT Ratio. Note: A.
  • Page 75 Q11. Can I use CT's that I currently own with PM-4324 Power Meter? You can use CT's that you currently own with PM-4324P (without CTs) Power Meter. The CT inputs of the PM-4324P can handle a maximum of 333mV of AC current. PM-4324P's current ratio is always full scale to 5A.
  • Page 76 example, on a 380 volt wye system, line to line voltage is 380 volts and line to ground voltage is 380/1.73 = 220 volts Q13. How about the harmonic (THD) analysis capability? PM-4324 User’s Manual v1.02 Last Revised: May. 2017 Page: 76 ...
  • Page 77 The number of harmonics N that can be analyzed within the 2.8 kHz pass band is the whole number of 2800/f. The absolute maximum number of harmonics accepted by the Energy Metering IC is 63. N = [2800/f], N ≤ 63 Q14.
  • Page 78 The voltage [V_x] register in Modbus register table can be used to show line-to-ground voltage or line-to-line voltage value by setting [Display Voltage] register value. According to different wiring types, it is required to set different [Display Voltage] value. If the voltage is not displayed as expected value, please refer to the table below and check if the setting value is set accurately.
