12. Using communication data
A BR/IO-Link Gateway is required to 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)
12.1. Connection to a BR/IO-Link Gateway GWY-CB
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 12.3. Overview of the communication data on page 30).
The communication connection C on the device allows the diagnostic line to be connected to the Gateway. The Ox/C con-
nection represents a non-safety-related communication channel between the Gateway and the connected devices.
IO-Link communication can be used for the following functions as well:
Ì Reset for acknowledging error messages
You will nd further information in the operating instructions for your BR/IO-Link Gateway.
12.2. Connection to a safety relay ESM-CB
The safety relay ESM-CB features an integrated BR/IO-Link Gateway. In addition to functioning as an IO-Link device (see
chapter 12.1. Connection to a BR/IO-Link Gateway GWY-CB on page 29), the device can be used for connecting two
monitored single- or dual-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 starting 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 Ox/C connection of the
device allows the diagnostic line to be connected to the Gateway.
You will nd further information in the operating instructions for your safety relay with integrated BR/IO-Link Gateway.
