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.

Installing the SLC to SCANport Module
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≤10 meters and D+B+C≤10 meters. However, 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.

Installing the SLC to SCANport Module
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.

Removing the SLC to SCANport Module
Where Do I Go From Here?
5.Apply firm, even pressure to seat the module in the I/O chassis backplane connectors. Make sure the plastic tabs snap into the rack.
6.Connect the SCANport cable(s) from the SCANport device(s) to the SCANport connections in the front of the module.
Important: You must keep in mind that the maximum cable 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.
You can insert or remove SCANport cables while a rack is powered. If a cable is removed while the channel is enabled, the connected SCANport device will fault unless otherwise configured at the SCANport device.
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.

Configuring the SLC to SCANport Module for Basic Mode
Using Basic Mode
Chapter 3 covers the following information:
•a description of what basic mode provides
•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.

To configure the SLC to SCANport module for basic mode using the Advanced Programming Software (APS), you need to:
1.Create a file.
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.

Example APS Screen
Highlight the processor you want to use. For example, 1747±L532.
4.Press the F2 key.
5.Depending on your processor and version of APS, you may be asked to enter the operating system that your processor uses.
6.Press F5 to configure the I/O. The screen shown in Figure 3.2 is displayed.

Prompt to Enter the Module ID Code
9.Enter the module ID code. For basic mode, the module ID code is 3516.
10.Press the Enter key.
When you have entered the module ID code, you are returned to the screen shown in Figure 3.2 with the selected module now shown. If you press F9, the screen shown in Figure 3.4 shows the configuration information for the SLC to SCANport module. You should not need to change this information for basic mode.

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:

Using Enhanced Mode
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.

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
! SCANport devices connected on each channel operate. Refer to the manual for your SCANport device for additional information.
Refer to Chapter 2 for the DIP switch configuration for fault/program state.
