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.

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.

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 (Accepting I/O Module Configuration)

This section will provide the user with the basic steps for configuring an MDSA on DeviceNet. It also contains specific examples of how to configure a device using RSNetWorx for DeviceNet.

The first step to setting up a system that contains an MDSA is to power up the MDSA DeviceNet module. Once it is powered up, it will attempt to determine the network baud, and set its baud rate appropriately. While the MDSA DeviceNet module is determining the network baud rate, the Mod/Net Status LED will blink green for ¼ second, red for ¼ second, then turn off. This pattern will be repeated until the baud rate is determined.

		If there is no traffic on the network, the device will not be able to
	IMPORTANT
		determine the network baud rate. The Mod/Net Status LED will to
		continue to repeat the green/red/off blinking pattern until network
		traffic is detected

Once the proper baud rate is set, the Mod/Net Status LED will either blink green or turn solid green. If the Mod/Net Status LED turns solid red, it has most likely failed its “Duplicate MAC ID Check”, which means that the MDSA DeviceNet module has detected another device on the network with the same node address or “MAC ID”. Note that automatic baud rate detection can be disabled to allow a baud rate to be manually configured (see Advanced Topics on page 3-12)

The first time that an MDSA DeviceNet module is powered up, the I/O Status LED will turn solid red. This indicates that the configuration of the I/O modules has not been accepted.

Publication 198-UM002A-EN-P December 2001

Operation 3-2

Accepting the configuration of the I/O modules is a part of the device configuration process outlined below.

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

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

2.Choose the appropriate DeviceNet/PC interface and click OK. RSNetWorx will tell the user to upload or download devices before viewing configuration.

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

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 browsing the network.

If the name of the device shows up as “Unrecognized Device” it means that the device is not registered. (see Advanced Topics on page 3-12).

Publication 198-UM002A-EN-P December 2001

3-3 Operation

The user is now able to configure the MDSA. The following steps outline how to accept the configuration of the I/O modules. This will result in the I/O Status LED changing from solid red to off.

1.Double click on the MDSA icon. RSNetWorx will verify the identity of the device, and then display the following screen:

2.Select the “Parameter” tab. RSNetWorx will prompt the user to upload the parameters from the device. Select the button. The following screen appears:

3.From the screen shown, verify that the number of I/O modules and the names of the modules recognized are correct. Select the Accept Config parameter (parameter 48 or 58). Double click the value of that parameter. A drop-down list of options will appear. Select the Accept Config option.

4.Select the button. RSNetWorx will ask you whether it should download the changes to the device. Select . The device will reset, and the I/O Status LED will turn off. The MOD/NET status LED will be flashing green, waiting to establish connections to other nodes.

Operation 3-4

DeviceNet MAC ID (Node Address) Configuration

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. Node addresses can be changed in three different ways. The first two ways outlined below are accomplished via DeviceNet using the software setting, while the third is done by setting the hardware switches that reside on the MDSA DeviceNet module.

		The MDSA must be offline before performing the following procedures.
	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 button and the node number will be changed. The second way of changing a node address can be done by following the steps shown below.

1.From the menu, choose The following screen will appear:

Operation 3-8

Choosing the I/O Assembly Data Format

Consumed Assemblies (sometimes referred to as Output Assemblies) define the format of I/O message data that is consumed by the MDSA. The MDSA generally consumes I/O messages to command the state of its outputs.

Choosing the size and format of the I/O data that is consumed by an MDSA is done by choosing a Consumed Assembly instance number. This instance number is written to the Consumed IO Assy parameter (parameter 34 in the Cat. No. 198-DN; parameter 24 in the Cat. No. 198-DNG). Refer to Appendix on page A-1 to determine which Consumed Assembly instance to select. The different instances/formats allow flexibility for different systems. The screen below shows the Consumed IO Assy parameter in the parameter list of a Cat. No. 198-DNG module.

		The Consumed IO Assy parameter value can not be changed while the
	IMPORTANT
		MDSA is online with a scanner. Any attempts to change the value of this
		parameter while online with a scanner will result in the error message
		“Object State Conflict”.

After the Consumed IO Assembly has been chosen and downloaded to the MDSA, select

and . This will update the I/O Consumed Size parameter value (parameter 48 or 38). Record this value to be used later in the Scanner I/O mapping.

Produced Assemblies (sometimes referred to as Input Assemblies) define the format of the I/O message data that is produced by the MDSA. The MDSA generally produces I/O messages that contain the fault status of the MDSA, and the state of the MDSA’s inputs.

Choosing the size and format of the I/O data that is produced by an MDSA is done by choosing a Produced Assembly instance number. This instance number is written to the Produced IO Assy parameter (parameter 35 in the Cat. No. 198-DN; parameter 25 in the Cat. No. 198-DNG). Refer to Appendix on page A-1 to determine which Produced Assembly instance to select. The different instances/formats allow flexibility for different systems. The

		MDSA is online with a scanner. Any attempts to change the value of this
		parameter while online with a scanner will result in the error message
		“Object State Conflict”.

After the Produced IO Assembly has been chosen and downloaded to the MDSA, select
