A 4.10 ILR2250
RS422 The data are configured or selected via ASCII commands or via the web interface.
Baud rate 115200 b/s ex factory
i
The sensor can continue to supply measured values to the RS422 output even while the sensor is communicating.
28 bits each output value are transmitted via RS422. Each data frame consists of the timestamp in ms and the distance in 1/10 mm,
followed by a footer byte.
- The sensor sends data in big endian format.
- Each value is transmitted in 4 bytes; the lower 7 bits are used for the data.
- The IF2035-PROFINET extracts the distance value from the data frame and deletes the flag bits.
- The 4*7 bits are combined into a 28 bit value.
- The IF2035-PROFINET sends data in little endian format.
Distance value in millimeter:
The user or a PLC must divide the transmitted value by 10 to obtain distance values with a resolution of 0.1 mm.
