Operating Instructions
Transponder-Coded Safety Switch CTS-C1-BP/BR-FLX
30
(translation of the original operating instructions) MAN20001587-01-02/23
12.3. Overview of the communication data
The switch transmits both process data that are continuously transmitted to the evaluation unit (cyclical data) and data that
can be polled specically as needed (acyclical data). For further information on connection and on the communication data,
refer to the operating instructions for your BR/IO-Link Gateway.
12.3.1. Cyclical data (process data)
Table 2: Cyclical data (process data)
Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0
Byte 1 OI - OER - OM - - OD
Byte 2 - - - - OLS - OL OT
Bit Signal Message
OI Diagnostics There is a fault, see chapter 15.3. Error messages on page 37.
OM Status The safety outputs of the device are switched.
OD Door position1 A valid actuator is detected in the actuating range, and the guard is closed.
OER Escape release The device has been unlocked manually.
OT Door position2 The actuator is inserted in the switch head and the guard locking can be activated.
OLS Locking element
The locking element is stuck, see chapter 15.3. Error messages on page 37.
OL
Guard locking Guard locking is active.
12.3.2. Acyclical data (device data and events)
After one of the commands listed below is sent, the requested data are provided via the IO-Link Gateway. The reply message
always consists of 8 bytes in big endian format.
Example1: Reply message for the command Send device ID number/serial number: 06 02 68 E0 00 01 17 00
In this example, the device’s ID number is 157920 and its serial number is 279.
