Figure 72 - MicroLogix 1400 Controller in a DH-485 Network
Example DH-485 Connections
The
following network diagrams provide examples of how to connect
MicroLogix controllers to the DH-485 network. You can connect a MicroLogix
1400 controller to your DH-485 network directly without using a RS-232 to
RS-485 converter and optical isolator, such as the Advanced Interface
Converter (AIC+), catalog number 1761-NET-AIC, as shown in Figure 73 on
page 184, because Channel 0 has isolation and RS-485 built-in.
However, you may need to use an AIC+ to connect Channel 2 of the MicroLogix
1400 controller to a DH-485 network. For more information on the AIC+, see
the Advanced Interface Converter and DeviceNet Interface Installation
Instructions, publication 1761-IN002.
