EcoStruxure IT Gateway 1.8.1 and newer include more accurate device support for the Uniflair family of CRACs and chillers. With the addition of these new DDFs, you will need to do a targeted discovery in EcoStruxure IT Gateway.
If you have previously discovered Uniflair devices, and have updated to Gateway 1.8.1, you must delete previously discovered Uniflair devices and then rediscover them. Existing device data will not be preserved.
Uniflair devices discovered in Gateway 1.8.1 or later are not affected.
Follow these steps to discover your Uniflair device:
- Enter the IP address of the device you want to discover.
- When the discovery finishes, you'll see this message:
- Click Choose device type to see a list of available device types, for example, Chiller or CRAC .
- Select the vendor Uniflair.
You'll see a list of all the available DDFs for your selection, Uniflair Chiller in this example.
This is a partial list of the Uniflair chillers. To determine which DDF is the correct one for your device, you need more information:
- The full model name of the device, for example, ERAF1221A.
- The PLC (programmable logic controller) and HMI (human-machine interface) your device is equipped with.
When you have this additional information, you can break down the DDF names and select the proper DDF.
Let's use an ERAC1221A equipped with a pCO5+ PLC and a UG50 HMI as an example.
The first part of the DDF name is the model name, followed by the model number (with x as a wildcard). You know it will be Erac_xx21a, but there are 2 DDFs that start with that combination. That's why you need to know which PLC and HMI are equipped.
IMPORTANT: Devices with the same model name but a different PLC/HMI are NOT compatible.
The correct DDF for this device is Erac_xx21a_pco5_plus_ug50_metric. If you selected Erac_xx21a_pco1_ug40_metric instead, measurements in EcoStruxure IT will be inaccurate,
Modbus discovery is similar to previous Gateway versions. There is a list for Type, Vendor, and Family (DDF name). The DDF names are structured the same as in step 5 of the SNMP discovery section. Enter the IP address and slave address and select Discover Modbus device.
