Using communication data
A device with a gateway function is required in order use the device’s communication data and forward them to a higher-level
bus system. The following devices are suitable:
Ì
GWY-CB-1-BR-IO (BR/IO-Link Gateway)
Ì
ESM-CB (safety relay with integrated BR/IO-Link Gateway)
9.6.1. Connection to a BR/IO-Link Gateway
The OD/C connection of the device allows the diagnostic line to be connected to the Gateway. The OD/C connection rep-
resents a non-safety-related communication channel between the Gateway and the connected devices.
The Gateway is an IO-Link device. Communication via IO-Link offers cyclical (process data) and acyclical (device data and
events) data exchange. See chapter
9.6.3. Overview of the communication data on page 17
The following information is transmitted:
Ì
Device information of the Gateway (electronic rating plate, states of the device)
Ì
State information about connected BR/BP switches
You will find further information in the operating instructions for your BR/IO-Link Gateway.
9.6.2. Connection to safety relay ESM-CB with integrated BR/IO-Link Gateway
The safety relay ESM-CB features an integrated IO-Link Gateway. In addition to functioning as an IO-Link device (see
Connection to a BR/IO-Link Gateway on page 17
), the device can be used for connecting two monitored single- or du-
al-channel sensor circuits. The sensor circuits evaluate various signaling devices:
Ì
Sensor circuit S1 with short circuit detection; suitable for single- or dual-channel safety sensors
Ì
Sensor circuit S2 suitable for OSSD signals; short circuit detection by signaling device
When at least one sensor circuit is interrupted, the safety relay initiates the safe state. Different relay stating behaviors and
various monitoring functions are possible.
The device’s safety outputs FO1A and FO1B are routed to the OSSD inputs of the safety relay.
The OD/C connection of the device allows the diagnostic line to be connected to the Gateway.
You will find further information in the operating instructions for your safety relay with integrated BR/IO-Link Gateway.
9.6.3. Overview of the communication data
The switches transmit both process data, which are continuously transmitted to the evaluation unit (cyclical data), and data
that can be polled specifically as needed (acyclical data). For further information on connection and on the communication
data, refer to the operating instructions for your BR evaluation unit. The integrated Gateway is used to implement the data
of a BR switch chain or a BP switch on an IO-Link slave.
