Connect the Card via a DH-485 Network
Figure 4.1 shows an example of a network consisting of three SLC 500
controllers and one programming station. This configuration requires the
1784-KTX or -KTXD card and three link couplers:
•
An SLC 500 CPU is connected to each of the link couplers (1747-AIC) with a
1747-C11 cable.
•
The 1784-KTX or -KTXD card is connected to the network at one of the link
couplers, as shown in Figure 4.1.
•
The communication cable consists of three segments of cable daisy-chained
at each link coupler.
