Application Examples E-3
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.
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-IV16
module. For this example, a single 16-bit rack connection is
configured to read/write the three discrete I/O modules. 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-IV16
