JC-120MC Programming
Before using a network register, the IP addresses and IP ports of the remote
network nodes must be written to two tables in the local register array.
If ... ... then ...
... you carry out network configuration in
the JetSym Hardware Manager,
... these tables are generated
automatically, see file ModConfig.da
below.
... you do not carry out network
configuration in the Hardware Manager,
... you must generate the tables in your
application program.
Content indexing of the tables is done via GNN of the node in the first part of
the register prefix (2).
Register Value range Properties
GNN 235000 ... 235199 Register table for
IP addresses
GNN 235400 ... 235599
Register table for IP ports
Note on the contents of the table:

GNN = Global Node Number in the range 000 ... 199
When you download the configuration files, the Hardware Manager transfers
the file ModConfig.da to the controller.
The OS of the controller loads this file when the controller is energized or
when the corresponding command is automatically issued by the Hardware
Manager after download.
The file
ModConfig.da lists registers with their corresponding values. The OS
enters the corresponding values into these registers.
This file also holds the IP addresses (register GNN) and port
numbers (register GNN) of the nodes on the network.
It is no longer required to enter values into registers via application program.
