To connect more than three SCANport devices in a single rack, add
additional SLC to SCANport modules to your SLC rack system.
You can use your SLC to SCANport module in a 4, 7, 10, or 13 slot
SLC rack or a 2–slot expansion rack available for the fixed I/O
configurations of SLC–500 processors.
Important: An SLC rack using this module needs an enclosure of at
least 200 mm (8 in) in depth. You cannot place an SLC
rack using the SLC to SCANport module in a 150 mm
(6 in) deep enclosure.

Chapter Objectives
Before You Install the Module
Chapter 2 covers the following information:
• what you need to do before you install the SLC to SCANport
module
• how to install the SLC to SCANport module
• how to remove the SLC to SCANport module
Important: You cannot place an SLC rack unit containing an SLC
to SCANport module in an enclosure that is less than
200 mm (8 in) deep.
Before you install your SLC to SCANport module, you need to:
• Determine the length of your SCANport cable(s).
• Determine the placement of your SCANport cables.
• Locate the DIP switch on your SLC to SCANport module.
Publication 1203–5.9 –– October 1996
2–2 Installing the SLC to SCANport Module
Determine the Length of the SCANport Cable(s)
To connect your SLC to SCANport module to a SCANport device,
you need to use an Allen–Bradley SCANport cable. The maximum
cable length between any two peripheral devices connected to any
SCANport device cannot exceed 10 meters (33 feet). Therefore, in
Figure 2.1, A+B+C
you would not add the length of cable E to cables A, B, C, or D
because it connects to a separate SCANport device (or channel).

Determine the Placement of the SCANport Cables
You must keep the SCANport cables away from high power cables.
If your SCANport cables are placed too close to the power cables or
run in parallel with power cables, you may introduce noise into the
communications system, which can cause problems to your system.
Make sure you physically mount and connect SCANport products
following the installation guidelines available for each product.

To install the SLC to SCANport module into the chassis:
1. Set the DIP switches. For each SCANport device connected to
the SLC to SCANport module, you need to set two DIP switches
to select what happens when the SLC processor or rack adapter
faults or is placed in program for the appropriate channel.

If you select a state other than Fault, the channel enable bits located
in the first two words of output data will retain their last state values.
This ensures that the enabled SCANport connections remain active
for those states. The I/O data transferred to the SCANport device
will change as configured by the DIP switch.
2. Turn off the chassis power supply.
ATTENTION: Do not install the SLC to SCANport
module with the chassis power supply on. Inserting or
!
removing the module with the chassis power supply on
may damage the module.
3. Select a slot for the module in the chassis. You may use any slot
except the leftmost slot, which is reserved for the SLC 5/xx
processor or rack adapter.
4. Insert the module into the slot you have selected.

SCANport device will fault unless otherwise configured at the
SCANport device.
distance between any two devices connected to a
single channel cannot exceed 10 meters (33 feet)
of cable. Also, the SCANport cables must not
be in close contact with the power cables.
Removing the SLC to SCANport Module
Where Do I Go From Here?
To remove the SLC to SCANport module from the chassis, you need
to:
1. Remove the SCANport cables.
2. Make sure the rack power is removed.
3. Push in on the hooks on both ends of the module.
4. Gently pull the module from the chassis.
The SLC to SCANport module can operate in either basic mode or
enhanced mode. Refer to Chapter 1 for a description of basic mode
and enhanced mode.

Chapter 3 covers the following information:

• how to configure the SLC to SCANport module for basic mode
• how to transfer data
Basic mode sends a 16–bit logic command and a 16–bit analog
reference from the module to each SCANport device. It receives a
16–bit logic status and a 16–bit analog feedback signal from each
connected SCANport device.

2. Enter a file name. For example purposes, we are using SM1_AP
as the file name.
3. Highlight the processor as shown in Figure 3.1.

Transferring Data
To transfer data using the SLC to SCANport module, you need to be
familiar with how the SLC I/O image table represents the internal
data I/O mapping and how the input and output image channel status
bits are defined.
When the SLC to SCANport module is configured as a basic mode
module, the internal data I/O mapping is represented within the SLC
image table as the following:
Output Image Input Image

meanings for the bits in the Logic Command and Logic
Status fields. They may also use the Reference and
Feedback differently. Refer to the manual for the
specific SCANport device for more information.

the connected SCANport device. When high (1), the channel
becomes active to the SCANport device and transfers the

disconnects from the SCANport device. This usually causes
the connected SCANport device to fault.

What Does Enhanced Mode Provide?
Chapter 4 covers the following information:
• a description of what enhanced mode provides
• how to configure the SLC to SCANport module for enhanced
mode
• how to use the I/O image
• how to configure G files
• how to use M files
Enhanced mode supports the basic mode features which include a
16–bit logic command and a 16–bit analog reference from the
module to each SCANport device as well as a 16–bit logic status and
a 16–bit analog feedback signal back from each connected
SCANport device.
In addition, enhanced mode optionally provides datalinks, safe state
data, and messaging.

4–2 Using Enhanced Mode
What Are Datalinks?
Datalinks let you cyclically transfer parameter values to and from a
SCANport device (provided that the SCANport device supports
datalinks). By using datalinks, you can change the value of a
parameter without using the SLC to SCANport messaging function.
Each datalink consists of two 16–bit words of input and two 16–bit
words of output when enabled. Up to 8 words in and 8 words out of
data are available if supported in the connected SCANport device.
SCANport devices that support this function have a group of
parameters for datalink configuration. These parameters are
identified as Data In A1–D2 and Data Out A1–D2. To use datalinks,
you need to:
1. Set up a configuration file, called a G file, to enable the datalinks
from the SLC to SCANport module side.
2. Configure or link the Data In A1–D2 and Data Out A1–D2
parameters in the SCANport device.
Setting up the G file is covered in more detail later in this chapter.
What Is Safe State Configuration Data?
You can select constant values that your SLC to SCANport module
will maintain in the event of an SLC processor mode change or error.
These constant values are referred to as safe state data. When the
SLC is placed in program mode or an SLC fault occurs, the control
outputs can be set to automatically switch to the constant values set
in the safe state data words. This lets you define a safe operating
state for controlled devices that depend on a pre–programmed output
from the module.
ATTENTION: Use the G file to configure your safe
state values based on your knowledge of how the
!
Refer to Chapter 2 for the DIP switch configuration for
fault/program state.
SCANport devices connected on each channel operate.
Refer to the manual for your SCANport device for
additional information.
