AL1431 IO-Link master with EtherCAT interface

9.3.7 Accessing the process data
The cyclic input and output data at pin 4 of the ports is stored in the Inputs (0x6000) and Outputs
(0x7000) object areas.
u To check the validity of the cyclic process data, read and evaluate the Port Qualifier
Information (PQI) of the port.
Even if the EtherCAT connection is interrupted, the PQI indicates that the process data is valid.
This may have an unintended impact on the control process.
u Take suitable measures to detect an interruption of the EtherCAT connection.
Available parameters:
Parameter Description Reference
Input Process Data Cyclic input data of the ports
Input Area (0x6000 - 0x6FFF) (Ò/70)
Output Process Data Cyclic output data of the ports
Output Area (0x7000 - 0x7FFF) (Ò/71)
In the “IO-Link” operating mode, max. 32 bytes each are available for input data and output data for
each port. The number of bytes transmitted is set when configuring the cyclic input and output data.
In the “Digital Input (DI)” operating mode, the process value of the port is mapped in the 1st byte of the
input data (object 0x60n0, subindex 0x01).
In the “Digital Output (DO)” operating mode, the process value of the port is mapped in the 1st byte of
the output data (object 0x70n0, subindex 0x01).
Valid values:
• 0x00: OFF
• 0x01: ON
The digital output data of pin 2 of ports X1...X4 is stored in the Device Area (0xF000).
Parameter Description Reference
Pin 2 Digital Output Con-
trol
Digital output data at pin 2 of ports X1...X4
Device Area (0xF000 - 0xFFFF) (Ò/76)
9.3.7.1 TwinCAT-specific information
During the configuration of the slot, TwinCAT automatically creates variable nodes for the process
data in the Solution Explorer:
Available objects:
• The cyclic input and output data at pin 4 of the port is grouped in the folders below the respective
EtherCAT module.
Node group Node Description
TxPDO • input byte 0
• input byte 1
…
• input byte n
1
Cyclic input data of the port (pin 4)
RxPDO • output byte 0
• output byte 1
…
• output byte m
2
Cyclic output data of the port (pin 4)
1
n: [3…31]; depending on the length of the configured input data of the port
2
m: [3…31]; depending on the length of the configured output data of the port
• The digital output data at pin 2 of the ports is located as a subfolder below the device node:
