A–16 Setting Up the DH-485 Network You can connect an unpowered link coupler to the DH-485 network without disrupting network activity. In addition, if an SLC 500 controller powers a link coupler that is connected to the DH-485 network, network activity will not be disrupted should the SLC 500 controller be removed from the link coupler. Installing and Attaching the Link Couplers 1. Take care when installing the link coupler in an enclosure so that the cable connecting the SLC 500 controller to the link coupler does not hit the enclosure door. 2. Carefully plug the terminal block into the DH-485 port on the link coupler you are putting on the network. Allow enough cable slack to prevent stress on the plug. 3. Provide strain relief for the Belden #9842 cable after it is wired to the terminal block. This guards against breakage of the Belden cable wires. Publication <strong>1747</strong>-6.2
This appendix provides an overview of the RS-232 communication interface and explains how the SLC 5/03, SLC 5/04, and SLC 5/05 processors support it. This appendix also provides information on the following: • RS-232 and SCADA applications • RS-232 communication interface overview • SLC 5/03, SLC 5/04, and SLC 5/05 processors and RS-232 communication • SLC 500 devices that support RS-232 communication • DF1 protocol and the SLC 5/03, SLC 5/04, and SLC 5/05 processors • ASCII communication • DF1 communication protocol modems overview • wiring connectors for RS-232 communication • applications for the RS-232 communication interface For online configuration procedures of the SLC 5/03, SLC 5/04, and SLC 5/05 processors for DF1 protocol, see your programming software user manual. RS-232 and SCADA Applications RS-232 is a communication interface included under SCADA (Supervisory Control and Data Acquisition) applications. SCADA is a term that refers to control applications that require communication over long distances. For more information about the use of Allen-Bradley equipment in SCADA applications, refer to the SCADA System Applications Guide, Publication Number AG-6.5.8. RS-232 Communication Interface Overview RS-232 is an Electronics Industries Association (EIA) standard that specifies the electrical, mechanical, and functional characteristics for serial binary communication. One of the benefits of RS-232 communication is that it lets you integrate telephone and radio modems into your control system. The distance over which you are able to communicate with certain system devices is virtually limitless. Publication <strong>1747</strong>-6.2
