Hello everyone,

I have question about S210 hardware ids. I am using S7-1515F with two S210 drives for my application. In order to connect PLC to drive I have to use Technology Objects with unique Hardware Identifier. At first I thought Hardware ID is unique from factory, but after setting up several PLC I have noticed that Hardware IDs sometimes are same (Customer 1: Hardware IDs are 269 for drive 1 and 280 for drive 2; Customer 2: Hardware IDs are 279 for drive 1 and 280 for drive 2). 

My question is, is it possible to set static Hardware IDs so that I would have one program with same hardware IDs for all customers, rather than remembering what Hardware ID each customer has ? 

Thank you!

Thank you for the answer.

Now by PLC variable do you mean set as datatype in datablock? Currently what I am doing is I have set Datablock for up to 8 drives where I define ID as int and converting it to HW_ID in order to assign to the Technology Object. I took this approach because we are using S7.NET communication for the SCADA program we have developed. 

The only downside is that on initial configuration of our software, we have to pass configuration with that ID (it is not too much work, but I was thinking if we can just statically assign the id, then we would not need the configuration at all, and all of the customers would have same IDs).

Is there a way to read the hardware ID as a tag? Basically that ladder logic could use that tag without hardcoding the hdw id number by me

 Found answer to this: PLC Tags -> Show all tags -> System Constants
