I have a Red Lion device and currently I have it mapped in the following way in Blue Open Studio. However, when migrating to Ignition, the values are not being converted correctly. I would like to know the correct way to map the addresses. I have been searching the documentation, but I have not been able to do it correctly.

Hey Jose\_Roberto\_Canales,

We will need some more information regarding how this device is being configured in Ignition

- Are you able to confirm the value coming off this device by using a third party software like ModScan?
- What driver are you currently using to connect to this device?
- What do the tags look like after addressing them from the Gateway?
- Have you tried creating a new opc item tag and manually addressing the tag?
- Can you try changing the the Modbus type to Holding Register Float (HRF) to see if you get the correct value

For further troubleshooting please reach out to our Support Department so we can create a ticket for this issue and we can dive deeper.

The difference in values is typical of reading using integer format when the data is really a floating point number. Change your mapping to use floating point format.
