Ethernet / IP connection - PR-43-AC - PR-43-AP - PR-43-GC - PR-43-GP - PR-43-PC

The MI implements an Ethernet / IP adapter that provides measurement data for connected scanners. Currently active MI app configuration determines the available measurement data and the Ethernet/IP connection parameters. Connection can be set up easily with the Windows PC tool “Vaisala MI/CI EDS Generator” that generates EDS files based on the requested MI app configuration. The tool is available at https://www.vaisala.com/en/industrial-measurements/products/liquid-concentration. When using the tool, select the apps that are configured for each appslot on MI, then press GENERATE EDS FILE and choose the name and location for the new EDS file.

The data content of the O > T and T > O instances is a combination of individual app data contents. The following tables provide the data content of individual apps.

Table 1. 60-byte data of Refractometer app (Recipe app has an identical set of output data)

Name	Bytes	Type	Function
Conc	0-3	REAL	Final concentration value
Temp	4-7	REAL	Process temperature
Calc	8-11	REAL	Calculated concentration value
nD	12-15	REAL	Calculated refractive index value
S/N	16-27	STRING	Refractometer serial number
Status	28-59	STRING	Refractometer status message

Table 2. 2-byte input data of Refractometer app

Name	Bytes	Type	Function
ExtWash	0-1	INT	External wash request input

Table 3. 2-byte input data of Recipe app

Name	Bytes	Type	Function
RecipeID	0-1	INT	Recipe identification number input

The connection can be set up manually with the following parameters: Port: 0xAF12 (44818)
