3 Construction and Function
3.1. Construction
The BIC components are designed for applications in an IO-Link system. They are
connected to the host master module via the IO-Link protocol. The system consists of the
following two components:
•
Base (master side)
•
Remote (device)
The components are enclosed in a brass housing protected acc. to IP 67
Master
The master is connected to the base.
Devices
The remote is connected to the device.
When IO-Link devices are connected, observe the following:
•
Make certain that the total power consumption is not greater than that of the base.
•
Use only devices with inputs
3.2. Function
This set transfers power from the base to the remote via an air bridge; the base then
receives IO-Link data back from the remote. The base and remote must match one another
with respect to size.
The IO-Link device is wired to the remote. The remote is only inductively coupled to the
base, however. The base transmits the energy for the IO-Link device to the remote. The
IO-Link communication of the IO-Link device is transmitted from the remote to the base.
The energy available for the IO-Link device is dependent on the distance and on the offset
between base and remote and is, therefore, limited. For this reason, the total current
consumption of the connected IO-Link device must not exceed the maximum power output
of the remote.
3.3. Features,
Advantages
•
The cable length between the remote and IO-Link device can be a maximum of
20 meters.
•
LED indicator on the remote and base for operational readiness and operating voltage
•
An angular offset is possible between base and remote
•
Simple wiring of e.g. rotary tables, replaceable punch heads etc.
•
M12 plug connection on the systems
•
Control of capacitive loads
•
More power in the same structural shape
•
Large operating voltage range
3.4. Indicators
If the supply voltage is applied correctly, the green LEDs on the base and remote illuminate.
If the IO-Link communication is active, the green LED on the base flashes inversely. The
base's red LED illuminates as soon as an error has been detected in the system.
As soon as the remote moves out of the secured working range, the red LEDs on the base
begin to flash. If the red LED illuminates and stays on, there is an error in the IO-Link
communication. If no device is connected to the remote but the remote is within range of the
base, the green LEDs flash.
