8.2.1 SDO Introduction 8.2.1.1 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 39
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.
ccs: client command specified 3: upload segment request scs: server command specified 0: upload segment response t: toggle bit. This bit must alternate for each subsequence segment that is uploaded. The first segment will have the toggle bit set to 0. The toggle bit will be equal for the request and response message.
Page 41
ccs: client command specified 1: initiate download request scs: server command specified 3: initiate download response n: Only valid if e = 1 and s = 1, otherwise 0. If valid, it indicates the number of bytes in d that do not contain data. Bytes [8-n, 7] do not contain segment data.
Page 42
Download Segment Protocol ccs: client command specified 0: download segment request scs: server command specified 1: download segment response seg-data: It is at most 7 bytes of segment data to be downloaded. The encoding depends on the type of the data referenced by index and sub-index. n: It indicates the number of bytes in seg-data that do not contain segment data.
8.2.1.3 Abort SDO Transfer Protocol In some conditions, the SDO client or SDO server will terminate the SDO transmission. For example, the value of entries that users want to modify does not exist or is read-only, even users wouldn’t continue the uncompleted SDO protocol under some special situations.
Page 44
Abort Code Description 0503 0000h Toggle bit not alternated. 0504 0000h SDO protocol timed out. 0504 0001h Client/server command specified not valid or unknown. 0504 0002h Invalid block size (block mode only). 0504 0003h Invalid sequence number (block mode only). 0504 0004h CRC error (block mode only).
8.2.2 PDO Introduction 8.2.2.1 PDO COB-ID Parameters Before the real-time data are transmitted by the PDO, it is necessary to check the COB-ID parameter of this PDO in the PDO communication objects. This parameter setting controls the COB-ID of the PDO communication, which is in 32 bits, and each bit with its meaning is given in the table follow.
Note: 1. Users can also define the PDO COB-ID by themselves. Actually, all COB-ID can be defined by users except the reserved COB-ID described in the table of the section 3.1. It is important to avoid the conflict with the defined COB-ID used in the same node.
The PDO, including the DI value, will be sent when the DI value is changed. And both transmission types will directly trigger an update of the mapped data when receiving the RxPDO. The PM-3033-CPS doesn’t support RxPDO. 8.2.2.3 PDO Communication Rule The PDO related objects are indicated from index 0x1400 to 0x1BFF.

Q4. What is the difference between line to line voltages to line to ground voltage? On a three phase wye connected system line to line voltages will be the voltages between the terminals A - B, B - C, A - C. On a three phase wye connected system line to ground voltages will be the voltages between the terminals A - N, B - N, C - N.

Q5. How to set up [Display Voltage] register value to correctly display line to ground voltage or line to line voltage? 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.

Q7. How to measure the Voltage large than 500V? For service voltage above 600 Vac, voltage transformers (PTs) are used to step down the voltage to a lower range that will work with a PM-3033 meter. Selecting a Transformer: Selecting the right voltage transformer is simple. Review the following considerations to determine the best fit for your application.
