Drive communication through Dataset

I have ABB acs800 drive and its communication with s300 plc is in field bus mode. And drive parameters no is 71. I cant cant understand what it is saying in its manual about dataset. I have enclosed some images of dive manual. Please help me out.

How numbering is made for dataset. What the hell this dataset is?

How it is communicating with the help of dataset. How and what is received and transmitted.

I cant underrstand.

Hello,

Parameter 71 is for field bus communication setting. How it communicates with master/controller/PLC i.e. via Profibus or Advant Link or CS31 or MODBUS etc. etc. Check value in P71.5 if it is 10 instead of 1, then add 9 in dataset numbers, e.g. DS1---->DS10, DS3---->DS12 etc.etc.

With Profibus 10 words data transmission is possible. Module has one element which unpack/decode one word into 16 bits. Updating time period for data set 1, 3 & 5 is 32 ms except speed ref, torque ref, & speed correction which is 8 ms.

Data set odd numbers i.e. DS1, DS3, DS 5 etc. are receiveing signals at drive end & Data set with even numbers i.e. DS2, DS4, DS 6 etc. are transimtting signals from drive.

User needs to establish the communication & select data transfer as per application demand/requirement.

HTH.

What is DS1---->DS10

DS3---->DS13

?

What information and in what format and how it is performed

Hello Flourine;

First, a dataset is simply,  in programmer's language, a structured collection of data, usually related to a single task. In this case the dataset refers to the control and status words required to talk to a specific drive, over many different field fieldbuses.

For a more general definition, look here:

https://en.m.wikipedia.org/wiki/Data_set

There seems to be a total of 9 datasets per drive, some of them are described in the screenshots you posted. You will use these to read and write values on the drive. Think of them as standard telegrams, allowing access to specific data, as shown in your screenshots.

On your first screenshot, the ABB techs describe the actual number of dataset required based on the value of a specific parameter on the drive. Look up the value of this parameter 75.1, it specifies the base address of each dataset DS1 to DS10). If the parameter  value is 1 (standard), use DS1...; if it is 10, then use DS10... (add a value of 9 to the dataset address).

Hope this helps,

Daniel Chartier
