The IO_Module function block enables communication with the OX024-x10 expansion module so thatadditional outputs can be used.

Configure CAN

Set up CAN so that CAN messages can be transmitted to and from the I/O module.

Input Type Range Description

CAN Bus —— In the GUIDE template, identify the CAN bus that contains CAN messages to and from the I/Omodule. Route this bus to the CAN input on this function block.CAN messages sent from the I/O module to the function block contain information about theI/O modules’ inputs, outputs and configuration. CAN messages sent to the I/O module from thefunction block set outputs and configurations.

Baudrate U32 50000–1000000 The Baudrate is the speed of the CAN Port.

Port Port —— Assigns the hardware CAN port that transmits the data.

AddrMode U8 0–2 I/O module addressing mode.0: Variable ID addressing mode. The I/O module Tx and Rx message identifiers are determinedby the I/O module measuring the voltage on its CAN shield input and matching that value with apredefined range and matching identifiers in the I/O Module CAN Message Identifiers table. TheCAN messages use 11 bit identifiers in this mode.1: Predefined ID addressing mode. The I/O module Tx and Rx message identifiers aredetermined by Node/N1. These identifiers are selected by matching to the N1 value in the I/OModule CAN Message Identifiers table. The CAN messages use 11 bit identifiers in this mode.2: Fixed ID addressing mode. The I/O module Tx and Rx message identifiers are determineddirectly by setting Tx ID and Rx ID. The CAN messages use either 11 bit or 29 bit identifiers inthis mode, as determined by Frame.

Tx ID U32 0x00–0x1FFFFFFF Tx ID is the CAN message identifier used by the function block for sending messages to the I/Omodule when using the Fixed ID addressing mode.When using the service tool to configure the I/O module, this value corresponds to the Rxparameter saved on the I/O module.

Rx ID U32 0x00–0x1FFFFFFF Rx ID is the CAN message identifier used by the function block for receiving messages from theI/O module when using the Fixed ID addressing mode.When using the service tool to configure the I/O module, this value corresponds to the Txparameter saved on the I/O module.

Frame U8 0–1 Sets CAN message identifier length when using the Fixed ID addressing mode.0: 11 bit ID1: 29 bit ID

Node/N1 U8 0–15 The KWP2000 node address used for communications between the I/O module and the PLUS+1®

Service Tool is Node/N1 x 8. For Variable ID addressing mode and Predefined addressing modethis value also determines the CAN.

Net U8 0–255 KWP2000 network used for communications between the I/O module and the PLUS+1® ServiceTool.

Enable BOOL —— Enables the function block to send CAN messages to the I/O module. An F/T transition or T atpower up starts initialization.

Enbl_RecheckCRC BOOL —— Determines if the I/O module CRC is periodically checked to ensure the device’s configurationmatches the function block’s configuration.T: The CRC is requested from the I/O module and compared every 5 seconds.F: The CRC is only requested from the I/O module during initialization.

Connections and Signal Overview

When more than one I/O module is used in an application, each block requires unique Inputs andOutputs bus connections. For example, IO_Bus, IO_Bus1, IO_Bus2 are needed.




Configure Communications Between Controller and I/O Module

Several parameters control the communication between the controller and the I/O module.

The I/O module hardware has two LEDs. The red LED blinks when the I/O module transmits a message.The green LED blinks when the I/O module receives a message. Both LEDs may appear to be constantlyon, because message transmissions repeat frequently.If communication is lost, the I/O module green LED blinks at a slow and constant rate.

Variable Addressing Mode

Variable addressing mode is the default addressing mode of the I/O module, but it is not the defaultmode for the function block.

When the device is powered, the CAN shield input voltage is measured. Communication parameters aredetermined from the I/O Module CAN Message Identifiers table. For proper communication between thefunction block and the I/O module, the corresponding N1 value from the table must be entered in thefunction block and AddrMode must be set to 0.

Every time the device is powered, the CAN shield input voltage must be within the same N1 range for thefunction block and device to reach the Configured status. After the device is powered, the CAN shieldinput voltage has no effect on communication.

Predefined Addressing Mode

Predefined addressing mode is the default addressing mode for the function block, but it is not thedefault mode for the I/O module.

In this mode, the I/O module reads the N1 value stored in non-volatile memory (EEPROM).

Because the function block and the I/O module use different default addressing modes, as long as the N1value determined in the I/O module matches the N1 value set in the function block, the device isconfigured using predefined addressing mode during all subsequent power cycles. As such, the properCAN shield voltage is only required during the first device initialization.

If setting the CAN shield voltage is not practical, use the PLUS+1® Service Tool to set the AddrMode to 1and to set the required N1 value.




Fixed Addressing Mode

Fixed addressing mode allows for any pair of CAN message identifiers to be used for I/O modulecommunication.

In this mode, the I/O module relies on the RX_ID, TX_ID, and Frame parameters for communication withthe function block. Use the PLUS+1® Service Tool to set the proper values to match the function block andto set the AddrMode.

Volatile Parameters

Once initial communication is established, all volatile parameter configuration messages are sent to theI/O module.

Non-Volatile Parameters

After volatile parameters are configured, the function block sends a request for the configuration CRC tothe I/O module.

If this number matches the locally calculated value, then the configurations stored on the I/O modulematch those set in the function block. If the numbers do not match, then all configuration commands aresent and the CRC is requested again.

You can use the PLUS+1® Service Tool to access all non-volatile parameters on the I/O module.

Timing Configurations

Timing for messages to and from the I/O module is established after all other configurations are sent.

CAN Bus Load

Adjust the average amount of message transmissions on the CAN bus to allow for bursts and otherincreased message transmission situations.

Any CAN bus has a maximum message transmission capacity. So, to allow for situations that can causeincreases in messages, minimize the CAN bus load.

The CAN bus load is the average amount of message transmission on a CAN bus. Use the PLUS+1® CG150USB/CAN gateway and CANKing software to view CAN bus loads.

PLUS+1® I/O modules communicate with their associated controllers over a CAN bus. System developerscan adjust I/O module RepTime and TimeOut parameters to manage CAN bus loading. Increasing thesetimes reduces the CAN bus load. Decreasing these times increases CAN bus load.

CAN Message Identifiers

The function block uses the following message identifiers to enable communication between thecontroller and the I/O module.

Troubleshooting

Find out how to ensure the outputs of the I/O module function properly, and make sure your changes toparameters are saved.

Problem Cause Solution

Outputs of I/O module do notfunction as expected. Configured isalways false.

The I/O module is using variable address modeand the CAN shield voltage does not fall withinthe range matching the function block’s N1value.

Use the I/O Module CAN Message Identifiers table to find thecorrect voltage and ensure it is applied to the CAN shieldduring power up.

Change the N1 value in the function block to match thevoltage applied to the CAN shield.

Incompat_HW is true. The function block iscommunicating with a device other than the I/Omodule.

Ensure the proper addressing mode and correspondingcommunication parameters are set on both the I/O moduleand the function block.

It is possible the I/O module is correctly configured, but asecond I/O module has a similar configuration. Reviewconfiguration and make changes to the other I/O modules.

Incompat_Protocl is true. The firmware on theI/O module uses a version of the I/O Protocol lessthan 2.00.

Update the I/O module with the latest firmware.

Incompat_Protocl is true. The firmware on theI/O module uses a version of the I/O Protocollater than version 2.99.

Replace the function block by using the latest availableHWD file.

When changing the I/O module ’sparameters with the PLUS+1® ServiceTool, those changes are not properlysaved.

A function block detects the changes and resetsthe parameters to the values specified in thefunction block.

Disconnect the function block’s controller before makingparameter changes. If the changes do not result in differentCAN message identifiers for the I/O module, thenreconnecting the controller results in the parametersreverting back to the values set in the function block.
