4 2002 Introduction Product Overview The 2002 is a sub-miniature valve product line featuring a variety of valve configurations and uses our G2-1 electronics. These include several serial / bus communication protocols which can control up to 24 valve solenoid coils on the valve side of the assembly and up to 16 points on the discrete I/O side. Points on the discrete I/O side may be inputs or outputs in groups of two. An optional sub-d jumper module allows these discrete I/O points to control an additional remote valve manifold with up to 16 valve solenoids. The Numatics Inc DeviceNet node is designed to DeviceNet specification, release 2.0 and supports the following I/O Message types: Polled, Change of State (COS), Cyclic and Combinations (i.e. Outputs can be set for Polled while Inputs can be set for COS for improved system response time). This manual addresses the specifics of configuring and commissioning the Numatics 2002 Series product configured with the DeviceNet communication interface. For more information relating to pneumatic valving and valve manifold assemblies, please refer to the latest Numatics 2002 Series catalog.

5 About DeviceNet Overview DeviceNet is a bus communication protocol used to network industrial devices to eliminate labor intensive and expensive point to point wiring schemes. It is based on the CAN (Controller Area Network) protocol. Allen Bradley originally developed DeviceNet, but it is now supported by a multitude of manufacturers. The ODVA (Open DeviceNet Vendor Association) is an independent organization that governs the DeviceNet specification and oversees conformance testing for products which will be used in a DeviceNet system. DeviceNet uses a powered 4-wire network and can have up to 64 nodes. The protocol can transfer a maximum of 8 bytes of data per node cycle with three selectable communication (baud) rates; 125 Kbps, 250 Kbps, or 500 Kbps. Maximum trunk cable distance depends upon baud rate and cable media type. Refer to the table below for details. More information about DeviceNet and ODVA can be obtained from the ODVA web site DeviceNet Features Features Description DeviceNet Spec.

6 2002 and G2-1 Electronics Modularity Discrete I/O The 2002 product line is a completely modular system. As shown below, all of the electronic modules plug together, allowing easy assembly and field changes. Page 6

7 Pneumatic Valve Manifold The pneumatic valve manifold is also modular. The valve solenoid coil connections are made automatically using Z-Board technology (plug together PC boards which allow internal connection from solenoid coils to output drivers without the use of wires). This allows easy assembly and field changes. Page 7

8 Distributing I/O with G2-1 Electronics 2002 DeviceNet System Versatility The 2002 series fieldbus manifold allows its discrete output points to be distributed from the central manifold by using the Sub-D Jumper option (see page 17). This distribution capability does not affect any network or communication node settings, and can be made at any time, even after the manifold has been installed and commissioned. The distributed I/O points can be used for various output devices, including additional manifolds with a Sub-D connector option. Please refer to Figure 1 on the following page for sample configuration layouts. Page 8

16 Discrete I/O Modules Rules The maximum number of I/O modules that can be used on the discrete I/O side of the manifold is 8 (Two masters and six slaves). Modules can be connected in any combination and sequence of inputs and outputs up to the logical limitations of 16 I/O. The first, and if required the fifth, module must be a master module. A master module differs from a slave module in that it contains the necessary circuitry to drive up to 8 I/O points. After 8 I/O points are used (1 master and 3 slaves) another master module is required. Each master or slave module allows for two I/O connections. The Sub-D type modules function as a master module. These modules may be located in either 1 st, 2 nd, 3 rd, 4 th, or 5 th positions. In the 1 st position, the Sub-D module may drive up to 16 I/O points. However, if the Sub-D module is located after the 1 st master module, it can drive only 8 I/O points. The Sub-D module must be the last module on the discrete I/O side.

18 Sub-D Output & I/O Modules There are two Sub-D module versions available: a Sub-D Output module, which can be used to drive up to 16 NPN Output points, and a Sub-D I/O module that can be used to access up to 16 remote discrete I/O points. Inputs are PNP (sourcing), Outputs are NPN (sinking, positive common). The Sub-D Output module allows the user to connect an additional valve manifold to the node. This increases the total number of valve solenoid outputs to 40. Sub-D I/O module can be used as an Output only device, an Input only device or a combination of Inputs and Outputs. However, the I/O module has two groups of eight selectable 2.7K ohm pull-down resistors for all 16 I/O points. These resistors are used for 2-wire sensors that need a small quiescent current to power their Input LED. The pull down resistors can also be used with 3-wire sensors, but are typically not needed. If the I/O module is used to control outputs, the resistors should be disabled to prevent trickle currents to connected loads. The factory default setting is with the (jumpers) shunts in the DISABLED position. To enable the resistors; move the (jumpers) shunts on the circuit board (inside the module) to the ENABLED position. There are two shunts; one enables/disables resistors for the first group of I/O (pins 1-8) and the other enables/disables resistors for second group of I/O (pins 9-16). Care should be taken to insure that total current draw from the Aux. Power connector does not exceed a combined maximum rating of 4 amps on the valve and discrete I/O pins. Sub-D Output & I/O Module s discrete points are available in groups of 8, depending on the number of discrete I/O master modules that are used. If no I/O master modules are used, there are 16 I/O points available through the Sub-D module. If a single discrete I/O master module is used, there are 8 I/O points remaining that are available through the Sub-D module. If two discrete I/O masters are used, there are no Output points available for use with the Sub-D module. (See table below) Discrete I/O Master Modules Used Discrete Output Points Available with Sub-D Module 16 8 N/A Pin Number N/A Master modules reserve 8 I/O points regardless of whether Slave modules are present.

Power Description Connector Pin # 1 Powers Outputs (Valves) 4 Powers Discrete I/O and Node Electronics Maximum system current capability is 4 amps. Care should be taken not to exceed 4 amp draw through pin #3, 0VDC common (pin #1 and pin #4 combined). Discrete I/O current draw is dependent on the device(s) connected. It is critical to know what these values are in order to remain safely within the 4 amp limitation. Loads should not draw more than 0.5 amps of current from any one individual discrete output point.

25 DeviceNet Configuration and Mapping EDS File The EDS file contains configuration information required to establish communication to a node on a DeviceNet network. An EDS stub file is loaded into the communication node prior to shipment and can be uploaded from the node with appropriate DeviceNet software (i.e. DeviceNet Manager, RS NetWorx, etc ). There are two EDS file s available for download, for the G2-1 series, the standard and the extended version. The standard EDS file contains s all parameters except the idle and fault action parameters. This allows efficient use of ADR function. The extended EDS file contains the idle and fault action parameters. These EDS files are available on the Numatics, Inc., website at or on the ODVA website at I/O Message Types The Numatics, Inc series DeviceNet communication node supports 3 different I/O message types. Below are brief definitions for the supported types: Polled The poll command is an I/O message that is transmitted by the Master. A Poll Command is directed towards a single, specific Slave (point to point). A Master must transmit a separate Poll Command Message for each one of its Slaves that is to be polled. The slave can respond with an I/O Message that is transmitted back to the Master. Cyclic The Cyclic message is transmitted by either the Master or the Slave. An Acknowledge Message may be returned in response to this message. The message is sent based on the value of a cyclic timer, which is set by the user. Change of State The Change of State message is transmitted by either the Master or the Slave. An Acknowledge Message may be returned in response to this message. The message is sent whenever a change of state occurs (i.e. an input changes from On to Off ). I/O Setup Outputs (Tx) Outputs are defined as any valve solenoid coil and/or any output point from a discrete output module. The output byte size (Tx) depends upon the physical configuration of the manifold as well as the Assembly Parameter settings (see the following explanation of Assembly Parameter). Please reference the following pages for a detailed explanation for calculating the output byte size (Tx). Inputs (Rx) Two types of inputs are recognized, discrete inputs and internal inputs. Discrete inputs are defined as input points from discrete input modules. Internal inputs are defined as input bits produced by output drivers. Thus the input byte size (Rx) will include discrete input points, as well as, internal inputs ( input bits). Please reference the following pages for a detailed explanation for calculating the input byte size (Rx). Page 25

26 Assembly Parameter (User Configurable Parameter #241) The Assembly Parameter is a user programmable option that allows the user to allocate the available I/O to valve coil outputs and discrete I/O as shown below. This allows the user to optimize the I/O byte size (Rx/Tx) to meet application requirements. The Assembly Parameter can be set via DIP switch SW3, Bit 7-10 (with node firmware Revision 2.4 or above, see page 13). Alternately, the Assembly Parameter can be easily set (in all node firmware revision levels) with appropriate DeviceNet Software (i.e. RS Networx, DeviceNet Manager, etc ), by sending an explicit message to the device: Send a set service to the Assembly Class (4), Instance (100), Data Attribute (3) using the Assembly Parameter data in the following table. Assembly Parameter 241 Valve Side Discrete Output Driver Bits Coil Outputs I/O Minimum Maximum * *Factory Default Setting The total number of input bits will be affected when changing Assembly Parameter data. Each assigned solenoid coil driver has an associated input bit which can be used for diagnostic purposes. These bits are mapped as inputs and are considered when calculating Input Byte Size (Rx). Page 26

27 I/O (Rx/Tx) Sizes Manifold Assembly - I/O (Rx/Tx) Size The overall size of the Input/Output (Rx/Tx) data for the manifold consists of the valve side data plus the discrete I/O side data. In the 2002 Series DeviceNet node, the Input/Output (Rx/Tx) size can vary from 0 to 5 bytes. Since there are many physical configuration possibilities for the 2002 series, the worksheet on page 27 will allow accurate sizing of the Input/Output (Rx/Tx) byte requirements. Valve Side - I/O (Rx/Tx) Size The Rx/Tx byte size for the valve side of the manifold consists of an output bit for each valve coil driver and an input bit for the corresponding input. The value for the valve side Rx/Tx byte size is determined by the user configurable Assembly Parameter (which is factory set to 5 bytes, 24 valve coil outputs and 16 discrete I/O) or by the manual dip switch settings in the Manual Configuration Module (MCM). Discrete I/O Side - I/O (Rx/Tx) Size The Rx/Tx byte size for the discrete I/O side of the manifold is configured based on the choice of I/O and/or Sub-D I/O modules, which are installed. The output (Tx) size will consist of an output bit for each output point. The input (Rx) size will consist of an input bit for each discrete input point and an input bit for each input from a corresponding discrete output. Sinking (NPN) outputs will return one bit for each output bit. The Assembly Parameter affects the I/O allocation of a manifold assembly. Sinking (NPN) output modules return one bit for each output bit. Rx/Tx Size Calculation Errors When the required manifold Input/Output (Rx/Tx) byte sizes are incorrectly set in the Allen- Bradley DeviceNet Configuration Software (i.e. RS Networx, DeviceNet Manager, etc.), the A-B DeviceNet scanner will error. The expected error code for this situation will be Error 77 Data Size Return Does Not Match Entry. Review your Rx/Tx size calculation to be sure they match the physical configuration of the manifold. Although the Rx/Tx values must be declared in the DeviceNet software for proper operation, they do not have to be mapped in the scanner. Page 27

28 Bit Mapping Rules Bit mapping for the 2002 series varies with the physical configuration of the manifold and the Assembly Parameter or dip switch configuration setting. The following is a breakdown of the bit mapping rules associated with the 2002 valve manifold. Valve Side Outputs (Tx) 1. coil outputs are distributed to the valve coils using the Z-Boards. 2. The valve solenoid coil output portion of the total output bytes (Tx) is dependent only on the Assembly Parameter setting or the dip switch configuration setting. Refer to page 13 for details. 3. Each solenoid coil output has an associated input bit (refer to Output Short Circuit r functional details). This will affect the overall input byte count (Rx). 4. coil output addressing begins at the first subbase nearest the node and continues in ascending order away from the communication node. 5. Each subbase is allocated 1 or 2 output bits, depending on the Z-Board type installed. Single Z-Board allocates 1 output bit, double Z-Board allocates 2 output bits. 6. Z-Boards can be used in any arrangement (all singles, all doubles, or any combination). Single solenoid valves can be used with double Z-Boards TM. However, one of the 2 available outputs will remain unused. Discrete I/O Side Outputs (Tx) 1. The discrete output byte size portion of Tx is always configured in byte increments, thus Master Module output bits, configured as a group of two, will always utilize a full byte (8 bits) when mapped. Although not used, the additional six bits in that byte are reserved for slave modules. 2. Discrete output bits are mapped in ascending order (away from the communication node) starting after the highest valve side output bit, which is dependant upon the Assembly Parameter setting or dip switch module configuration setting. (see page 13). 3. All discrete output modules have an associated internal input bit, which will affect the total number of input bytes (Rx). Note: Sinking (NPN) output modules allocate one internal input bit for every output point. Inputs (Rx) 1. The discrete input byte size portion of Rx is configured in byte increments. 2. Internal input bits, associated with the valve side output drivers, are always mapped before any physical input points. The quantity of these internal input bits depends upon the Assembly Parameter setting or dip switch module configuration setting. (see page 13.) Sinking (NPN) output modules allocate one internal input bit per output point for every output point. Page 28

36 User Configurable Parameters The Numatics 2002 DeviceNet manifold allows the user to set many options which define how the manifold behaves in certain instances. The following is a description of these options (parameters). All of these configurable parameters can be adjusted using appropriate DeviceNet configuration software (i.e. RS Networx, DeviceNet Manager, etc ) and initiating the explicit messaging function. Some parameters can also be adjusted using the optional manual configuration module. Parameter # User configurable parameters are divided into seven groups, which are described in the following table. Name Description MCM Settings Explicit Message Information Class Instance Attribute - MAC ID Node address SW3 & Baud Rate Network speed SW1-1, Outputs 1-40 Allows outputs 1-40 to be forced on and off. N/A Inputs Monitor / Read only (Not Configurable) N/A Output 0-40 Idle Determines whether to use idle Action Attribute value attribute or hold last state N/A Output 0-40 Idle Value Attribute Defines state of output point N/A Output 0-40 Fault Determines whether to use idle Action Attribute value attribute or hold last state N/A Output 0-40 Fault Value Attribute Determines whether to use fault value attribute or hold last state N/A Assembly Parameter Allocates how many valve output drivers are mapped (0,8,16,24,32) SW Autobaud Determines whether Autobaud is enabled or disabled Note: Above table assumes EDS file version 2.6 or above. SW Explicit messages provide multi-purpose, point-to-point communication paths between two devices. These messages use the typical request/response-oriented network communication used to perform node configuration and problem diagnosis. Explicit messages typically use low priority identifiers and contain the specific meaning of the message as part of the data field; including the service to be performed and the specific object attribute address. Each explicit message uses a four level address; Node Address (MAC ID), Object Class Identifier, Instance and Attribute. Example 1: Change MAC ID Setting- To set the MAC ID for a node specify the appropriate node address (MAC ID), service code 16 (Set Attribute Single), Object Class Identifier 3 (see chart), Instance 1 (see chart), Attribute 1 (see chart) and Data to the MAC ID (node address) desired. Example 2: Setting Output Idle Action Attribute- To set the idle action attribute to hold last state for valve coil #4 specify the appropriate node address (MAC ID), service code 16 (Set Attribute Single), Object Class Identifier 9 (see chart), Instance 4 (see chart), Attribute 7 (see chart) and Data 1. Page 36

37 Idle Action and Fault Action Parameters Parameters are used to describe characteristics or behaviors of specific output points (bits). The parameters shown below are used to determine what happens to a particular output as a result of what occurs in the system. The two actions that provide for output determination are Idle and Fault. The output Idle and Fault parameters allow individual control of each output point on the manifold. The user, through configuration software, can determine how a specific output behaves when a fault or idle action occurs. These settings are non-volatile and thus will not change upon loss of power. The 3 behavior options are: 1) Hold Last State 2) De-Energize 3) Energize Page 37

38 Idle Action Sequence Idle Action and Idle Value attributes determine what the outputs do if the device encounters an Idle Event. An Idle Event is defined as a transmitted message with no application I/O data, for example, this could occur if the PLC is put into program mode. The process for determining the output status during an Idle Action is as follows: 1) The device receives an Idle. 2) The device determines what action to take based on the Idle Action attribute setting. 3) If the Idle Action attribute is 1, the output holds its last state. 4) If the Idle Action attribute is 0, the Idle Value is checked. a) If the Idle Value attribute is 0, the output de-energizes b) If the Idle Value attribute is 1, the output energizes Page 38

39 Fault Action Sequence Fault Action and Fault Value attributes determine what the outputs do if the device encounters a Fault Event. A Fault Event is defined as one or more of the I/O connections timing out. This could be caused by a failure of the node, failure of the master, or problems with the network communication and/or wiring. The process for determining the output status during a Fault Action is as follows: 1) A Fault occurs (timer has timed out) for the device. 2) The device determines what action to take based on the Fault Action attribute setting. 3) If the Fault Action attribute is 1, the output holds its last state. 4) If the Fault Action attribute is 0, the Idle Value is checked. a) If the Fault Value attribute is 0, the output de-energizes b) If the Fault Value attribute is 1, the output energizes Page 39
