Configure a Module Connection
Next, we need to configure a module connection for the 1746-BAS
module.
1 . Right-click the 1746-BAS module in the Scanlist Configuration
window.
2. Select Insert Connection.
A Connection Properties window appears.
3. Choose Exclusive Owner - Advanced for the connection name.
For this example, we must choose M-file addresses for this type
of connection. The series B module communicates via eight I/O
words and 64 M1 and 64 M0 file words. These Basic module
M-file words are independent of the 72 M-file words transferred
to and from the Basic module. These 72 M0 and 72 M1 file
words reside in the 1747-SCNR scanner and are used to store the
data sent to the 1747-ACNR15 module from the SLC-5/04
processor and to store the data received from the 1747-ACNR15
for the SLC-5/04 processor.
The M0-file words in the 1747-SCNR scanner, which are assigned
in the Connection Properties screen, are M0:3.3 through M0:3.74.
These are the 72 words sent from the SLC-5/04 processor to the
1747-SCNR. Words M1:3.3 through M1:3.74 are the 72 words
received from the 1747-ACNR15. M-file words M1:3.0 through
M1:3.2 and M0:3.0 through M0:3.2 are reserved (please refer to
Chapter 2 of this manual for details). The next available Status
Address is M1:3.600/02, since bits 0 and 1 are used for the rack
connection.
