Chapter 13 IO-Link Communication Module AS04SIL
13-11
13.3.1.5 Automatic IO-Link Baud Rate Setting
AS04SIL-A can automatically match one of existing baud rates (4.8kbps, 38.4kbps and 230.4kbps) of IO-Link devices and
communicate with them. Thus there is no need to set the baud rate at communication ports for connected devices.
13.3.1.6 Connected Device Verification
As long as the Type Compatible option under Inspection Level is enabled and the setting is downloaded, AS04SIL-A will
check if the IO-Link device actually connected matches the product model of the configured device. If not matched, the
status code of the communication port will show 16#8CA2 which indicates that the connected device is inconsistent with
the configured one.
13.3.1.7 DI (Digital Input) Function of IO-Link Pin2
The IO-Link system may not respond fast enough for high-speed applications. When the connected IO-Link sensor
supports the second output, connect the sensor’s pin2 to DI of the port of AS04SIL-A. At this moment, the sensor can still
be watched and set up via the sensor’s pin4.
The real-time data can be monitored through Port 1- 4 Pin2 value of Normal Exchange Area. See the following figure as
an example.
The mapped register for Port 1- 4 Pin2 value of Normal Exchange Area is D29029. For the pin2 input value, the
addresses D29029.0~ D29029.3 correspond to port 1~ port 4 respectively.
DI1-DI4 of AS04SIL-A can also be used separately as standard inputs.
13.3.1.8 IO-Link Communications Error Detection
This function detects I/O-Link cable breaks, disconnections from IO-Link device ports, error-level device events, device
configuration verification errors, and IO-Link device malfunctions. See section 13.5 for IO-Link event codes.
