2. Chapter 2 Quick Start This chapter can help you to get started using the DH 485 RS 232C Interface Module catalog number 1747 KE The procedures included here assume that you have a basic understanding of SLC 500 products You should understand electronic process control and be able to interpret the ladder logic instructions required to generate the electronic signals that control your application Because it is a start up guide this chapter does not contain detailed explanations about the procedures listed It does however reference other chapters in this book where you can get more information about applying the procedures described in each step If you have any questions or are unfamiliar with the terms used or concepts presented in the procedural steps always read the referenced chapters and other recommended documentation before trying to apply the information This chapter e tells you what tools and equipment you need e lists preliminary considerations e explains how to install the module e describes when to configure the module e discusses system start up procedures Required Tools and Have the following tools and equipment ready Equipment e Medium blade screwdriver e Programming equipment RSLogix 500 software Publication 1747 UM005B EN P March 2006 2 2 Quick Start Procedures Publication 1747 UMO005B EN P March 2006 Unpack the Module Remove the items from the packa

17. In remote mode the module appears transparent to the half duplex master so that remote SLC 500 controllers can be polled directly as individual slaves on the half duplex network The interface module responds to the half duplex master if the station address specified corresponds to the node address of any token passing station on the DH 485 network connected to that interface module Communicate with the Interface Module 3 5 Messages from the remote nodes on the DH 485 network such as the SLC nodes use the destination address of the module Normally the module responds to a message from the DF1 master by swapping the source and destination addresses in the received message assuring that the reply message is sent to the proper DF1 master station If a DH 485 node initiates a message to the DF1 master the module overwrites the destination address with the master station value configured in the Remote mode submenu The message received by the half duplex master will contain a source address equal to the station address specified in the poll packet and a destination address equal to the address of the half duplex master device Remember that half duplex DF1 group addresses are in octal and DH 485 node addresses are in decimal The table on page 3 6 provides the conversion using the group number Publication 1747 UMO005B EN P March 2006 3 6 Communicate with the Interface Module Publication 1747 UMO005B EN P March 2006
