The software attempts to communicate with all possible node
numbers on the network, from 1 to 99. The online network
screen appears. For this example, the screen should show node
99 as the programming terminal as shown below.
Node 1 is the 1747-SCNR scanner and node 3 is the
1747-ACNR15 module. The 1747-ACNR15 module resides in slot
0 of its chassis, while slot 1 contains a 1746-IA16 module, slot 2
contains a 1746-OB16 module, and slot 3 contains a 1746-NIO4V
module. For this example, two separate ControlNet connections
are configured. The first is a Discrete 16-Bit Exclusive-Owner
rack connection for the two discrete I/O modules. The second
will be a Module Connection to the 1746-NIO4V 2 input/2
output analog module. Before we create this connection, we
should verify the chassis configuration for the 1747-ACNR15
module. To do this:
5. Right-click the 1747-ACNR15 module.
6. Choose Edit Chassis and verify that the chassis configuration is
as follows:
• slot 0: 1747-ACNR15
• slot 1: 1746-IA16
• slot 2: 1746-OB16
• slot 3: 1746-NIO4V
