Fig. 7.15 Configuring the Ethernet communication
NOTES:
SM2 IP ADDRESS
IP address of SeedMaster 2.
It must be entered even if only the refractometer is connected to its Ethernet port.
The first three dot-separated 3-character numbers in the SM2 IP ADDRESS must
be identical to the similar ones of the refractometer. They will be automatically
copied in the PR-23 IP ADDRESS field.
NETWORK MASK AND GATEWAY
If the SeedMaster 2 is connected to a network, they should be set according to the
network parameters.
MODB. DEV. ADDR.
MODBUS device address: 1…254
DHCP SERVER
If YES was selected, the SeedMaster 2 will provide the IP addresses to the network
participants.
Attention: only one DHCP server can be configured in a network.
PR-23 IP ADDRESS
IP address of the refractometer, for example: 192.168. 0. 1
The last 3 characters in the PR-23 IP ADDRESS can be selected in the 1…254
range, but they must be different than the similar ones in the SM2 IP ADDRESS.
Only the last 3 characters (XXX) can be changed.
Attention: check if the IP address set in the refractometer is identical to the PR-23
IP ADDRESS.
7.8.3 Organizing the two-way data transfer.
Data measured on-line by the instruments can be sent either directly to SeedMaster 2 or to the PCS. In the
later case the PCS will transmit them to SeedMaster 2 for use. The CONFIGURATION and SET UP
parameters of SeedMaster 2 will tell the device where to get these data from (see Ch. 7.2).
Communication between SeedMaster 2 and a PCS may operate in both ways and it must be based on the
exchange of fixed data fields containing data registers. It is the user’s responsibility to organize the data fields
containing the registers and program the communication in the PCS.
For a detailed description of communication and data exchange see Ch. 11.
NOTE:
The communication program of the PCS should be configured taking into account the organization of
data in SeedMaster 2. Naturally if two instruments (I1 and I2) are active, both of them should have
their own data fields in the PCS.
