8.2 Set up INPUTS
8.2.1 Data types and specifications
Calculations running in SeedMaster 2 rely on 2 types of data inputs:
1. data measured on-line (real-time data) by some instruments, and
2. data determined time to time in the local laboratory.
The possible types of data sources are (see Ch. 7.2):
On-line data : Transmitter, Communication.
Laboratory data : Transmitter, Keyboard, Communication.
Inputs from standard current transmitters.
SeedMaster 2 has 8 individually isolated standard current (4-20 mA, or 0-20 mA, configurable) input
channels. These can be connected to any device (including traditional transmitters and PCS-s) capable to
transmit measured data as standard current output.
Inputs from K-PATENTS PR-01-S type process refractometer(s).
One or both of the data (concentration, temperature) measured on-line by a K-PATENTS refractometer can
be transmitted to SeedMaster 2 by using one or two out of its 3 Serial Communication Ports (COMX).
Inputs from the K-PATENTS PR-23-…type process refractometer(s).
One or both of the data (concentration, temperature) measured on-line by K-PATENTS refractometer(s) can
be transmitted to SeedMaster 2 by using the Ethernet. Up to two sensor heads can be connected to the
Indicating Transmitter (ITR) of a PR-23-… type refractometer.
Inputs transmitted from a PCS using digital COMMUNICATION.
If the instruments are already transmitting their data to a PCS, one or all of these data together with
laboratory data can be transmitted to SeedMaster 2 by using digital data communication. Communication
may be based on the use of one of the 3 COMX Ports, or the ETHERNET.
Laboratory data
Some laboratory data, like feed syrup purity (%) and crystal content (at the end of strike, % by volume) can
be entered using standard current (4-20 mA), keyboard manual entry, or digital data communication (COMX
port, or Ethernet).
NOTE: Feed syrup purity can be sent as standard current only if purity is constant all over the strike (one
feed syrup only).
Syrup parameters (“m”, “b” and “c”) can be entered by keyboard manual entry, or by digital data
communication (COMX port, or Ethernet).
SUMMARY OF DATA INPUTS:
On-line (real-time) data:
• Mother liquor concentration (%)
• Temperature ( ˚C)
