The 1746 platform provides the choice of a fixed-hardware
system and a modular-hardware system. The
fixed-hardware SLC processors have 20, 30, or 40 built-in
digital I/O. By adding an expansion chassis, you can add 2
modules for a maximum of 64 additional I/O. The SLC
processors for modular systems are single-slot modules that
you place into the left-most slot of a 1746 I/O chassis. For

an SLC 5/03, 5/04, or SLC 5/05 processor is interfaced thru a

ControlNet I/O scanner module provides a ControlNet I/O
scanner port for an SLC 5/02, 5/03, 5/04, or 5/05 processor,
that lets the processor communicate over the ControlNet link
with I/O at remote locations. In each of the chassis remote
from the processor, a 1747-ACN or -ACNR15 I/O adapter
module provides I/O modules in those chassis with an
interface to the ControlNet link. In this configuration, the SLC
processor monitors/controls the I/O in its local I/O chassis as
well as the I/O in the remote locations.

2-Slot Expansion Chassis 1746-A2
1 With the addition of a 2-slot expansion chassis to the Fixed-Hardware-Style Controller, a maximum of 32 additional I/O of any type (ac/dc/contact)
can be installed. However, the following modules are incompatible with these controllers: 1746sc-INI4I, 1746sc-INI4VI, 1746-HS, 1746-HSCE,
1746-QV, 1747-SN, 1747-SDN. Also, some combinations of modules are incompatible because of backplane current loading. See publication
1747-2.30 for details of module compatibility.

1 Modbus slave protocol is embedded in the RTU-5/03 processors available from an Encompass partner. The Modbus slave protocol is supported on the RS-232 port (channel0). For information
on the Encompass program, see page 15-11.
2 The absolute maximum number of I/O for these processors only reflects the I/O addressing capability. It does not take into account the amount of memory that may be required for a
ladder-logic program to monitor and control the I/O. The practical ratio of memory per I/O is totally dependant upon your specific application.
3 You cannot configure this number of I/O for these processors with local I/O only. To configure this number of I/O for these processors, you must add a 1747-SN Remote I/O Scanner module to
configure I/O on a Universal Remote I/O link, add a 1747-SDN DeviceNet Scanner module to configure I/O on a DeviceNet network and/or add a 1747-SCNR ControlNet Scanner module to
configure I/O on a ControlNet network.

2 With this processor, you can also install a 1747-SN Remote I/O Scanner module to configure I/O on a Universal Remote I/O link and/or add a 1747-SDN DeviceNet Scanner module to
configure I/O on a DeviceNet network. You can configure 32 I/O chassis per Universal Remote I/O scanner using complementary I/O. If you don’t use complementary I/O, you can configure
16 I/O chassis per Universal Remote I/O scanner. With the DeviceNet scanner, you can address a maximum of 63 DeviceNet devices over the DeviceNet network.
3 An SLC 500 or SLC 5/01 processor can only receive messages and send reply messages to command messages sent from other nodes on the DH-485 network; it cannot initiate
communication.
4 The SLC 5/03 has an RS-232 port, which can also be configured for a DH-485 network, enabling the SLC-5/03 to connect to two DH-485 networks simultaneously.

Description — The blow molding module is an intelligent I/O module that can provide a maximum of 4 axes of closed-loop parison control on most
types of blow-molding machines. You can use multiple modules on machines with more than for heads. Configurations include accumulator push-out
control and three parison axis and two accumulator push-outs and two parison axes. The module is designed to work in a variety of plastic machine
applications including accumulator machines, continuous extrusion machines, and reciprocating screw machines. The module performs its servo
control task independently, but but receives its configuration and run-time information from the SLC processor. Also see the Plastic Machinery

Control Module ±100mV 24V dc
Description — The barrel temperature control module is an intelligent I/O module that can accommodate 4 heat/cool PID loops for barrel
temperature control applications. The module has 4 analog inputs, each of which functions as the controlled variable (C) input for a PID loop. The
PID algorithm is performed on the module for each of the loops. The manipulated variable (M) output of each loop is sent from the module to the
SLC processor’s data table as both a numeric value and as a time-proportioned output (TPO) signal. Your ladder logic can send either the M numeric
value to an analog output module, or the TPO signal to a digital output module to close the loop. For very fast cut-off, your ladder logic can use the
TPO signal transferred to the input image. The module provides auto-tuning of PID loops (optimized for tuning barrel temperature control loops),
self-calibration (external reference required) self-diagnostics, and detection of input open-circuit (including thermocouple break). Also see Process
Control (section 10). Also see the Plastic Machinery Control application products description on page.11-6.

Description — The mold cavity pressure module is an intelligent I/O module that monitors mold-cavity pressure sensors, to “measure” the formation
of plastic parts. The module also processes and extracts cyclic injection molding data (hydraulic pressure, screw position, and mold pressure) for
display on your PC and responds to alarms that you set to monitor critical molding parameters. When used with the Pro-Set 200 Injection molding
control system, the module helps you achieve a quicker setup time to obtain optimum part quality and helps you maintain that quality over the
production run. The module is compatible with RSLogix 500 programming software from Rockwell Software and DARTWin software from RJG
Technologies, Inc. Also see the Plastic Machinery Control application products description on page.11-6.

output to interface with proportional or servo valve amplifiers. The module is designed for use with the Hydraulic Configurator, a software product
that you can obtain from the Allen-Bradley web site on the Internet. The Hydraulic Configurator is an interactive executable that lets you configure
the module and tune its axes. The Hydraulic Configurator saves considerable time when troubleshooting or tuning axes. Applications include:
plywood presses, roll positioning, palletizers and stackers, forges, and hydraulic tailgate loaders. Also see the Hydraulic Control application

Description — The 1746-QV module is part of an SLC-based open-loop control system for controlling the speed and placement of a hydraulic
ram. The module accepts motion profiles that you program into the SLC processor and monitors an input from a linear displacement transducer.
The SLC processor sends to the module a pair of extend and retract profiles that define when to accelerate or decelerate hydraulic motion. This
ability toprogram these changes of speed reduces cycle time and reduces or eliminates pressure spikes and water-hammering for smoother
operation and less wear and tear on the machine. This also saves energy and enables faster part new-part change-over. The module fits simple
hydraulic applications including simple hydraulic presses, die-casting machines, and weld-head placement. The module provides OEMs and
system integrators with a less complex way to match hydraulic cylinder pressure or speed with application requirements. Also see the Hydraulic
Control application solutions description on page 11-25.

Cables are available in lengths of 0.5m, 1.0m, 2.5m, and 5.0m. To order, insert the code for the desired cable length into the catalog number (“005” = 0.5m,
“010” = 1.0m, “025” = 2.5m, and “050” = 5.0m). Example: Catalog number 1492-ACABLE005A is for a 0.5m cable that could be used to connect a 1492-AIFM4I-F-5
IFM to a 1746-NI4 I/O module. For more details on configuring the catalog numbers, see section 14.
 Each cable for analog I/O has an overall shield. On 1492-ACABLE
C and 1492-ACABLE
D, the drain wire is connected to the shield terminal on the I/O module
connector. All other 1492-ACABLEs have a ring lug on a 200-mm (8.87-in) exposed drain wire at the I/O module end of the cable.
 One pair not connected to I/O module connector; 2 additional pair not used.
 One conductor not connected to I/O module connector; one additional conductor not used.
