Due to the large flexibility resulting from the use of the above resources, a large number of I / O combinations
can be realized. Fig. 7.3 shows the basic I / O traffic organization of SeedMaster 2.
SeedMaster 2 relies on the use of process refractometers manufactured by K-PATENTS OY, Finland. The
main data output features of the presently available K-PATENTS refractometers can be summarised as
follows:
Refractometer:
Analog output: Communication Communication
(4 – 20 mA) (RS232, RS422, RS485) (Ethernet)
PR-01-S
1 YES, 1 port NO
(single sensor) + 1 (option)
PR-23- …
2 NO YES
(2 sensors)
SeedMaster 2 is prepared to be used with any combination of K-PATENTS process refractometers and can
be readily integrated in a Process Control System (PCS) with compatible I / O data traffic (analog, digital I /
O, and / or digital data communication) features.
Application examples
1.) Basic (or "stand alone") application, handling a single pan using a PR-01-S refractometer.
