Chapter Chapter Objectives Module Location and Keying This chapter describes the procedures for installing your remote I/O adapter module.
2–2 Installing Your Module Setting the Module Configuration Plugs You need to set configuration plugs on the remote I/O adapter module to use 32-point I/O modules, . You access the plugs through the access hole on the left side of the module (Figure 2.2). Each plug is inserted on two pins of a three-pin connector. Thermocouple Input Modules (Cat. No. 1771-IX and -IY) are not compatible with 32-point I/O modules. Figure 2.
Installing Your Module 2–3 Figure 2.
2–4 Installing Your Module link response - unrestricted or series B emulation. Certain scanner modules with multiple communication ports require a delay in the link turnaround time to allow the central processing unit (CPU) in the scanner sufficient time to service all communication ports. Without this delay, some incoming information may be missed while the scanner is servicing another port. This results in multiple communication retries.

Chapter 3 Addressing Modes for Your Remote I/O Chapter Objectives When you configure your remote I/O system, you must consider: • how to address your I/O • what combination of I/O modules and I/O chassis you can use These topics are discussed in this chapter. Hardware Addressing Programmable controllers that use the 1771-ASB remote I/O adapter module can address their I/O in 2-slot, 1-slot or 1/2 slot I/O groups.
3–2 Addressing Modes for Your Remote I/O Figure 3.1 An I/O Group Ć Up to 16 Input Terminals and 16 Output Terminals # " ! # " # " ! # " # " # " ! %! " # %! " # I/O racks are made up of I/O groups (Figure 3.1). An I/O rack is an addressing unit that can contain up to eight I/O groups. Figure 3.
Addressing Modes for Your Remote I/O 2ĆSlot Addressing 3–3 Definition: The processor addresses two I/O module slots as one I/O group. Concept: Each physical 2-slot I/O group is represented by a word in the input image table and a word in the output image table. Each input terminal corresponds to a bit in the input image table word and each output terminal corresponds to a bit in the output image table word.
3–4 Addressing Modes for Your Remote I/O Using StandardĆdensity I/O (8 point) Modules Standard-density I/O modules provide eight input terminals or eight output terminals. Figure 3.3 illustrates the 2-slot I/O group concept with two 8-point input modules. Figure 3.4 shows an 8-point input module and an 8-point output module in a 2-slot I/O group. Figure 3.
Addressing Modes for Your Remote I/O 3–5 Figure 3.
3–6 Addressing Modes for Your Remote I/O Figure 3.
Addressing Modes for Your Remote I/O 3–7 Identifying I/O Groups You identify your I/O groups in one of three ways, depending on the addressing method and I/O chassis you use. Refer to: • Figure 3.6 for 2-slot addressing when using series A I/O chassis. • Figure 3.7 for 2-slot addressing when using series B I/O chassis. • Figure 3.13 for 1-slot addressing when using series B I/O chassis. Figure 3.
3–8 Addressing Modes for Your Remote I/O Figure 3.
Addressing Modes for Your Remote I/O Complementary I/O with 2ĆSlot Addressing 3–9 Some processors support a complementary I/O configuration. Refer to the user manual for your processor to see if it supports this type of configuration. You configure complementary I/O by duplicating an I/O rack number of one I/O chassis (primary) in another I/O chassis (complementary), I/O group for I/O group.
3–10 Addressing Modes for Your Remote I/O Follow these guidelines when configuring your remote system with complementary I/O chassis: • Assign the complementary I/O rack number to a chassis of equal or smaller size than the primary chassis. • If the complementary chassis is smaller than the primary one, set the last chassis switch on the complementary chassis to the ON position, unless the adapter is in the faulted I/O search mode.
Addressing Modes for Your Remote I/O 3–11 Module Placement with 2Ćslot Addressing Figure 3.9 shows possible module placement when configuring complementary I/O with 2-slot addressing. Figure 3.9 Complementary I/O Configurations with 2Ćslot Addressing / (+ / 5 0 *- 1 ' 0 0 (0 / - 2 . 2+ !$/ - + .
3–12 Addressing Modes for Your Remote I/O • When using double-slot block-transfer modules: • The left slot of the complementary I/O group must be empty. • You can only place an 8-point output module (if any) in the right slot of the complementary I/O group. • When using single-slot block-transfer modules: • The right slot of the primary I/O group can be another single-slot block-transfer module, or an 8-point input or output module. • The left slot of the complementary I/O group must be empty.
Addressing Modes for Your Remote I/O 1ĆSlot Addressing 3–13 Definition: The processor addresses one I/O module slot as one I/O group. Concept: The physical address of each I/O group corresponds to an input and output image table word. The type of module you install (8, 16, or 32-point) determines the number of bits in these words that are used.
3–14 Addressing Modes for Your Remote I/O Thirty-two-point I/O modules need 32 input or 32 output bits in the processor’s image table. Because only 16 input and 16 output bits are available for each I/O group, to address a 32-point I/O module, the remote I/O adapter module uses the unused input or output word associated with the adjacent I/O slot. Refer to Figure 3.12.
Addressing Modes for Your Remote I/O 3–15 Identifying I/O Groups You identify your I/O groups in one of three ways, depending on the addressing method and I/O chassis you use. Refer to Figure 3.13 for 1-slot addressing when using series B I/O chassis. Figure 3.
3–16 Addressing Modes for Your Remote I/O Module Placement with 1Ćslot Addressing Figure 3.14 shows possible module placement for complementary I/O with 1-slot addressing.

Addressing Modes for Your Remote I/O 3–17 • When using double-slot block-transfer modules: – The left slot of the two corresponding I/O groups must be empty. – You can place any single-slot I/O module in the right slot of the two corresponding I/O groups. When using single-slot block-transfer modules, the corresponding I/O group must be empty.
3–18 Addressing Modes for Your Remote I/O When you select 1-slot addressing, each individual slot (one I/O group) is assigned to the corresponding word in the input or output image tables. You assign one I/O rack number to eight I/O groups (Figure 3.16).

Addressing Modes for Your Remote I/O 1/2Ć Slot Addressing 3–19 Definition: The processor addresses one-half of an I/O module slot as one I/O group. Concept: The physical address of each I/O slot corresponds to two input and two output image table words. The type of module you install (8-, 16-, or 32-point) determines the number of bits in these words that are used.
3–20 Addressing Modes for Your Remote I/O Assigning I/O Rack Numbers with 1/2Ćslot Addressing The following rules apply when you assign I/O rack numbers for 1/2-slot addressing: • One assigned I/O rack number is made up of eight I/O groups (Figure 3.18).
Addressing Modes for Your Remote I/O 3–21 Figure 3.
3–22 Addressing Modes for Your Remote I/O Complementary I/O with 1/2ĆSlot Addressing Some processors support a complementary I/O configuration. Refer to the user’s manual for your processor to see if it supports this type of configuration. You configure complementary I/O by duplicating an I/O rack number of one I/O chassis (primary) in another I/O chassis (complementary), I/O group for I/O group.
Addressing Modes for Your Remote I/O 3–23 Follow these guidelines when you select 1/2-slot addressing: • Place input modules opposite output modules; place output modules opposite input modules. • You can use 8, 16 and 32-point I/O modules. • Output modules placed opposite output modules reflect the same bits in the output image table. You can use block-transfer modules in a complementary I/O configuration with 1/2-slot addressing.
3–24 Addressing Modes for Your Remote I/O Acceptable Chassis Combinations Not all chassis combinations are acceptable in making I/O rack number assignments. For example, a 1771-A4B I/O chassis cannot complete an assigned I/O rack number that starts in a 1771-A1 I/O chassis. Refer to Figure 3.B for acceptable beginning I/O group numbers when making your I/O rack number assignments. Table 3.

Appendix D This appendix presents some of the most commonly asked questions about application and operation of the Remote I/O Adapter Module. Questions and Answers The following questions and answers do not cover all possible questions, but are representative of the more common ones. Q. What happens to my inputs and outputs when an adapter communication failure occurs? A.
D–2 Questions and Answers Q. I just added a rack to my remote I/O network and my PLC-5 scanner channel autoconfiguration does not recognize it. Why not? A. This is typically the result of installation and configuration problems. Anything from adapter power, wiring and connections, terminations, improper setting of adapter and chassis module switches. Use the scanner and adapter status indicators as a troubleshooting tool. Easy checks include 1.
Questions and Answers D–3 Q. My remote I/O is working fine without termination resistors. Are they really required? A. Yes, termination resistors are required. Any change in the RIO network installation (i.e. cable length, baud rate) can cause a remote I/O communication failure without proper termination. Installing termination resistors reduces the chance of this occurring. Q. I have an existing PLC remote I/O system that I’m replacing with 1771.
D–4 Questions and Answers Q. How do I add a 1771-ASB adapter module to my SLC 1747-SN scanner remote I/O network? A. Enter the correct rack number, rack size and starting group in the SLC500 program I/O configuration G-file data screen. With the correct communication rate set on the scanner, download the program to the SLC processor and switch to Run mode. Communication to the adapter will commence. Q. Ever since I installed fiber optics on my remote I/O network, the adapters won’t communicate. A.
