PLUS+1® Compliant OX024-x10 Function Block

OX024-x10 Function Block

The IO_Module function block enables communication with the OX024-x10 expansion module so that additional 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/O
module. 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 the I/O modules’ inputs, outputs and configuration. CAN messages sent to the I/O module from the function 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 determined by the I/O module measuring the voltage on its CAN shield input and matching that value with a predefined range and matching identifiers in the I/O Module CAN Message Identifiers table. The CAN messages use 11 bit identifiers in this mode. 1: Predefined ID addressing mode. The I/O module Tx and Rx message identifiers are determined by Node/N1. These identifiers are selected by matching to the N1 value in the I/O Module 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 determined directly by setting Tx ID and Rx ID. The CAN messages use either 11 bit or 29 bit identifiers in this 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/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 Rx parameter 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 the
I/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 Tx parameter 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 ID 1: 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 mode this value also determines the CAN.
Net U8 0–255 KWP2000 network used for communications between the I/O module and the PLUS+1® Service
Tool.
Enable BOOL —— Enables the function block to send CAN messages to the I/O module. An F/T transition or T at
power up starts initialization.
Enbl_RecheckCRC BOOL —— Determines if the I/O module CRC is periodically checked to ensure the device’s configuration
matches 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.

OX024-x10 Function Block
Input Type Range Description Enbl_ResetTest BOOL —— Determines if the I/O module volatile memory is periodically checked to ensure the device has
not lost volatile configuration information due to temporary loss of power. T: Volatile information is requested from the I/O module and compared every 1 second. F: Volatile memory is not checked after initialization and temporary loss of power to the I/O module may go undetected.
BusRecvryTm U16 0–65535 BusRecvryTm sets the time the I/O module CAN port waits after going into a “bus off” condition
before attempting to go back on the bus. 1000 is 1 ms.
DriverRecvryTm U16 0–65535 DriverRecvryTm sets the time the I/O module CAN port waits after a CAN error causes the
driver to reset before attempting to go back on the bus. 1000 is 1 ms.
RepTime_Supply U16 0–65535 Determines how often the Power, Sensor Power, and CAN Shield input values are transmitted
from the I/O module. 1000 is 1 ms.
RepTime_Status U16 0–65535 Determines how often the Output Status values are transmitted from the I/O module.
1000 is 1 ms.
RepTime_Outputs U16 0–65535 Determines how often the Output values are transmitted to the I/O module.
1000 is 1 ms.
TimeOut_Outputs U16 0–65535 Sets the maximum time allowed between commands for each output. If a command is not
received by the I/O module before the TimeOut_Outputs elapses then that output reverts to its default output value and default pin configuration. 1000 is 1 ms.

Inputs – Power Supply

The status of power supply input on the connector and pin C1p02 is described.
Signal Type Direction Range Description C1p02_Pwr Bus —— ——
AnIn U16 Input 0 – 32767 Analog input AD count.
Due to CAN message optimization, this value is approximated by scaling the Volt signal.
Volt U16 Input 0 – 36000 Analog input voltage
100 is 100 mV.
Updated BOOL Input —— True when the AnIn and Volt signals are refreshed.

Inputs – CAN Shield

The status of analog and CAN0 shield inputs on the connector and pin C1p05 is described.
Signal Type Direction Range Description C1p05_AnIn Bus —— ——
AnIn U16 Input 0 – 32767 Analog input AD count.
Due to CAN message optimization, this value is approximated by scaling the Volt signal.
Volt U16 Input 0 – 5250 Analog input voltage.
100 is 100 mV.
Updated BOOL Input —— True when the AnIn and Volt signals are refreshed.
