System Description

The Bulletin 198 Modular-DSA I/O System is a cost-effective, glandular I/O system designed specifically for Distributed Starters (Figure 1.2) and general starter panels. The Modular-DSA I/O System consists of a DeviceNet module followed by up to 16 I/O modules. The modules can be arranged in any combination and appear as one node on a DeviceNet network. Since the Modular-DSA I/O System was designed specifically for Distributed Starters, it not only provides the ability to control and monitor devices such as motor starters, sensors, solenoids and load feeders, but also provides for cable connections to those devices, eliminating the expense and problems of traditional wiring.

Product Overview 1-2

Figure 1.1 Typical Distributed Starter — Modular-DSA I/O System Modules Mounted on a Gland Plate in an Enclosed Combination Motor Starter

The Modular DSA I/O System can be mounted traditionally on a DIN Rail or on a Gland Plate to accrue benefits of wire simplification.

The Modular DSA I/O System mounted to a gland plate allows for easy connection from outside the enclosure for DeviceNet, standard sensors, and other auxiliary devices via M12 micro quick-disconnect connectors.

The Modular-DSA I/O System provides specially designed modules that provide many benefits in a distributed architecture. The Sensor Module (198-IB2S) is specifically designed to interface standard photoelectric and proximity sensors from the area surrounding the enclosure. Since the connection for standard sensors is available outside the enclosure via an M12 connector, and power is sourced from DeviceNet, no additional wiring is necessary.

The Starter Modules (198-IA2XOW1, 198-IB2XOB1, and 198-IB2XOW1) are designed to provide a fast, effective way to control and gather the basic information from either a DC operated or an AC operated starter.

The connections to specific 190D/191D Compact Combination Starters are made via cable harnesses, such as Cat. No. 198-MSACBL6. Additionally, the 198-IB2XOW1 module sources input power from DeviceNet. This allows many applications to turn off control power and still be able to read the inputs for diagnostics.

Module Installation

The I/O System can be mounted either on a DIN Rail or a Gland Plate.

Installation 2-4

IMPORTANT

During gland plate or DIN Rail mounting of all devices, be sure that debris (metal chips, wire strands, etc.) do not fall into the module. Such debris could cause damage on power-up.

IMPORTANT

When attaching I/O modules, it is very important that the modules are fully seated on either the DIN Rail or the gland plate. This ensures that the module-to-module connectors are properly mated and that the modules are properly grounded.

DIN Rail Mounting

The Modular-DSA I/O System modules can be mounted using either the 35 x 7.5 mm (EN 50 022-35 x 7.5) or 35 x 15 mm (EN 50 022-35 x 15) DIN Rail.

Operation

Chapter Objectives

This chapter contains the following information:

• Configuring the Modular DSA I/O System

• DeviceNet Explicit Messaging

• MOD/Net Status LED

• I/O Status LED

Basic Configuration

This section will provide the user with the basic steps of bringing up a device, such as the MDSA, on DeviceNet. This section will assume that the user has RSNetworx and a Cat. No. 1770-KFD module.

The first step to setting up a system is to power up the device. Once the DeviceNet module is powered up it will attempt to determine the network baud rate of the other devices on the network. After determining the network baud rate, it will set its baud rate to the same baud. While the module is determining the baud rate of the network, the MOD/NET Status LED will blink green for 1/4 second, red for 1/4 second, and then turn off.

IMPORTANT

Once the proper baud rate is set, the MOD/NET LED will either blink green or turn solid green if a connection is established between it and another device. If the LED turns solid red, it has failed the duplicate MAC ID check. The above sequence is done when the Autobuad rate is enabled. This sequence can be disabled to allow a baud rate to be manually configured (see Advanced Topics, page 3-14).

Once the unit has determined the baud rate of the network, the MOD/NET Status LED will be solid green, indicating that the device is on-line and operating in a normal condition. The I/O Status LED will be solid red, indicating that the configuration of the I/O modules has not been accepted.

Publication 198-UM001B-EN-P September 2001

If there is no traffic on the network, the device will not be able to determine a network baud rate. The MOD/NET Status LED will continue to execute the above sequence until network traffic is detected.

3-2

To begin the configuration of DeviceNet, execute the RSNetworx software and complete the following procedure.

1. From the 1HWZRUN menu, choose 2QOLQH. After “online” has been selected you will see the following screen:

2. From the options shown on the above screen, choose the appropriate PC interface and click OK. RSNetworx will tell the user to upload or download devices before viewing configuration.

3. Select the OK button. RSNetworx will now browse the network and display all of the nodes it has detected on the network.

Publication 198-UM001B-EN-P September 2001

3-3

RSNetworx will display an icon and the name and node address of each device on the network. The figure below shows the RSNetworx window after the browse of the network.

If the name of the device shows up as “Unrecognized Device” it means that the device is not registered. (see Advanced Topics, page 3-14).

The user is now able to configure the communications between the I/O modules. To begin the configuration of the communications between the I/O modules follow the steps below.

1. Select and right click the Modular DSA 198-DNG icon. The following list of options should appear.

Publication 198-UM001B-EN-P September 2001

2. Select SURSHUWLHV. RSNetworx will verify the identity of the device and then the following screen will appear:

3. Select the “Parameter” tab. RSNetworx will then prompt the user to upload the parameters from the device. Select the 8SORDGbutton. The following screen appears:

Publication 198-UM001B-EN-P September 2001

3-5

4. From the screen shown, verify that the number of modules and the name of the modules recognized are correct. Select the Accept Config.parameter (parameter 3 or

35). Double click the value of that parameter. A drop-down list of options will appear. Select the “Accept config.” option.

5. Select the Apply button. RSNetworx will ask the user whether it should download the changes to the device. Select yes. The Device will recycle power and the I/O status LED will no longer be red. The MOD/NET status LED will be flashing green, indicating that the device is properly connected to the network and is waiting to establish connections to other nodes.

DeviceNet MAC ID(node address)

The DeviceNet node address may be set to a value from 0…63. Note that, in most DeviceNet systems, node address 0 is usually reserved for the master device. Node address 63 is generally the factory default for slave devices. The node addresses can be changed in three different ways. The first two ways listed below are accomplished using the software setting, while the third one is done by setting hardware switches that reside on the 198-DN or

-DNG module.

IMPORTANT

1. The first manner of changing the node address is accomplished by double clicking on the existing node number. The user will then be able to erase the existing node number and enter the desired node number. Once the desired node number has been entered, deselect the device and the following screen will appear:

2. From the above screen select the <HVbutton and the node number will be changed.

The MDSA must be offline before performing the following procedure.

Publication 198-UM001B-EN-P September 2001

3-6

The second way of changing a node address can be done by following the steps shown below.

1. From the 7R ROV menu, choose 1RGH&RPPLVVVLRQLQJ« The following screen will appear:

2. Click the %URZVH button to upload the network. The following screen will appear:

Publication 198-UM001B-EN-P September 2001

3-7

3. From this screen select the appropriate PC interface. For our example we will use the 1770-KFD-1. After the appropriate interface is chosen the following screen appears:

4. Select the MDSA device and press the 2. button. After RSNetworx has finished updating the network the following screen will appear:

Publication 198-UM001B-EN-P September 2001

3-8

5. Choose the desired node address and click the $SSO\button. Click the ([LW button. The unit will then reset.

6. Re-browse the network to establish a connection with the new address.

The final way to set the unit’s node address is by directly setting the node address switches found on the DeviceNet Control Module. The factory-default setting is still node address 63.

3. To change the settings of a parameter, click the pull down tab on the desired parameter. For example, when you click the pull down tab on the $XWREDXG parameter, you will see a list box with available choices for this parameter. After choosing the desired setting,click the $SSO\ button. You will then be asked to download the configuration to the device; select the \HV button.

ATTENTION

Injury or damage may occur when parameters are not set according to the application requirements.

When this parameter has the value (QDEOH, the Modular DSA DeviceNet module will attempt to match the network baud rate at power-up. When this parameter has the value 'LVDEOHG, the power-up autobaud feature is disabled. When the Autobaud parameter is changed, the new value will be applied when the power is cycled after saving to the device. (The Autobaud screens are shown above.)

Choosing an I/O Assembly Format

In the Groups field, select the “Configuration” group. The following screen will appear:

Refer to Appendix A to determine which I/O assembly data format to select. The different I/O assembly formats allow flexibility for different systems. Assemblies 100 and 101 are
