PLUS+1® Compliant OX012-x10 Function Block
OX012-x10 Function Block
The IO_Module function block enables communication with the OX012-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.

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. |
