ii) In the "Source Element” field, enter the read tag you wish to access
(refer to section 11.7.3.3.1). In this example, we will be reading a
total of 21 16-bit words beginning at DB_w_2050 (database
address 2050).
iii) Enter the Number Of Elements to read. In this example, we will
read 21 16-bit words.
iv) For the Destination Element, either directly type in “data_array[50]”,
or select element #50 in the data_array tag via the drop-down box.
The destination could be any offset in the data_array tag, as long as
the offset plus the Number Of Elements (21) does not exceed the
tag’s defined size (73).
d) “Communication” tab settings (refer to Figure 74):
i) Enter the Path to the gateway. A typical path is formatted as
“
Local_ENB,2,target_IP_address ”, where:
•
Local_ENB is the name of the 1756-ENBx module in the local
chassis (we named ours “EIP” in section 11.7.3.1),
•
2 is the Ethernet port of the 1756-ENBx module in the local
chassis, and
•
target_IP_address is the IP address of the target node.
In our example, this path would be entered as
“EIP,2,192.168.16.102”.
ii) If “Cache Connections” is enabled (checked), the connection
remains open after transmission. If disabled (unchecked), the
connection is opened before and closed after every transmission.
For efficiency, it is recommended to enable “Cache Connections”.

e) Click “OK” to close the MSG Configuration dialog. At this stage,
MainRoutine should look like Figure 75.
