A-B PLC-5 DATA HIGHWAY PLUS
A target display can communicate on the Data Highway Plus Local Area Network (LAN) through a
serial port connection to an external Data Highway Plus Module or through a Data Highway Plus
Module attached to the target display.
The following drawing illustrates a Data Highway Plus connection between a target display equipped
with an optional Data Highway Plus Module and a PLC-5.
The following drawing illustrates a Data Highway Plus connection between a target display, a 1770-
KF2/B and a PLC-5. The target display utilizes a serial connection to an A-B 1770-KF2 Interface
Module. Some models of the PLC-5, such as the PLC-5/30, have a DF1 port that can be used for direct
connection to the target display. (See PLC-5 DF1 in a previous section.)
The following drawing illustrates a connection between a target display, a 1785-KE Module and a Data
Highway Plus link.
