2 Overview
Module structure:
A module consists of
}An electronic module
}A terminal block with cage clamp terminals and
}A backplane
The electronic modules are plugged into the backplane and determine the function. The
backplane is used for communication between the head module and the electronic modules
and forms the carrier unit for the electronic modules. The terminal block is plugged into the
electronic modules and is used to connect the field wiring.
Details of the terminal blocks that can be used are available under "Intended Use".
2.1 Module features
The product has the following features:
}IO-Link master in accordance with IO-Link specification v1.1
}4 IO-Link ports for connecting 4 IO-Link devices or 4 sensors / 4 actuators respectively
}Voltage outputs L+/L- for sensor and actuator supply
}Supported transmission rates:
– COM1 (4.8 kBd)
– COM2 (38.4 kBd)
– COM3 (230.4 kBd)
}Up to 32 bytes of process data per port
}Up to 128 bytes of process data, including header, per module
}Device configuration saved in the master
}Energy-saving functions
}LEDs for:
– IO-Link mode
– Module error
– Operating status

4 Function description
4.1 Process data
}The size of the IO-Link master's process image is variable. It depends on the size of the
process image of the devices that are used.
}The IO-Link master's process image of inputs (PII) consists of the PII of the devices and
a 3 Byte header.
}The IO-Link master's process image of outputs (PIO) consists of the PIO of the devices
and a 3 Byte header.
}The header always precedes the devices' process data.
}The maximum size of the process image of inputs (PII), including the header, is 128
Bytes per module and 32 Bytes per port.
}The maximum size of the process image of outputs (PIO), including the header, is 128
Bytes per module and 32 Bytes per port.
Example of the module's process image
The example below shows the structure of the process image for the IO-Link master mod-
ule. A process image size of 8 Bytes was used for the example. The example uses two IO-
Link sensors, each with a process image size of 2 Bytes and an IO-Link actuator with a pro-
cess image size of 1 Byte. Unused bytes are filled with zeros.
