C–4 Setting Up the DH+ Network Typical DH+ Network Configuration The following figure illustrates a possible configuration for the SLC 5/04 processor on a DH+ network. You can also use an SLC 500, SLC 5/01, SLC 5/02, SLC 5/03, or SLC 5/05 processor in place of the SLC 5/04 on the DH+ network if the 1785-KA5 card is used with a PLC-5. IBM-PC, XT, or compatible with 1784-KT, 1784-KTX, or 1784-KTXD APS PLC–5/15 DH+ Network PLC-5/15 with a 1785-KA5 SLC 500 5/04 Modular Controller 1747–PIC Interface Converter The PLC-5 and 1785-KA5 are daisy chained together. DH 485 Network 1747–AIC 1747–AIC 1747–AIC 1747–AIC SLC 500 5/02 Modular Controller SLC 5/03 CPU (1747-L532) The DH+ protocol uses factory set timeouts to restart token-passing communication if the token is lost because of a defective node. Other devices that use the DH+ network include those in the table below.

This appendix provides a brief introduction about control networks. For information on control networks, see the DCM User Manual, Catalog Number 1747-NM007, RIO Scanner User Manual, Publication Number 1747-6.6 and the DeviceNet Scanner Configuration Manual Publication Number 1747-6.5.2. Allen-Bradley Remote I/O Network PLC-5 or SLC 5/02, SLC 5/03, or SLC 5/04 proceesors with 1747-SN scanner The Allen-Bradley Remote I/O Network is a master/slave control network that enables chassis of I/O, operator interface terminals, push-button panels, I/O blocks, message displays, drives and much more to be great distances from the host PLC processor. The SLC 500 fixed, SLC 5/01, SLC 5/02, SLC 5/03, SLC 5/04, or SLC 5/05 can interface to this network through the 1747-DCM module for distributed control. The DCM allows the SLC 500 to look like another device on the network. Below is an example of the Allen-Bradley Remote I/O Network. Fixed 1747–DCM SLC 5/01 1747–DCM SLC 5/03 1747–DCM 1771–Remote I/O Network PanelView Operator Terminal With the SLC 5/02, SLC 5/03, SLC 5/04, or SLC 5/05 processor, a 1747-SN Remote I/O Scanner can be used as the master of a remote I/O network. With a SLC 5/02, SLC 5/03, SLC 5/04, or SLC 5/05 and SN, a PLC is 1747 not required on the network. 1747 1747–SN 1771–Remote I/O Network PanelView Operator Terminal Block I/O 1747–ASB 1747–ASB Publication 1747-6.2
