8. RS232 communication protocol
RS232 communication protocol PC ⇔ colorSENSOR OT-3-...-200-20
Sensor
(colorCONTROL C4
V6.4)
- Standard RS232 serial interface without hardware-handshake
- 3-wire: GND, TX0, RX0
- Speed: 19200 baud factory setting, can be changed (example 190) to 9600, 19200, 38400, 57600, 115200
8 data-bits, no parity-bit, 1 stop-bit in binary mode, us (unsigned), MSB (most significant byte) first.
The control device (PC or PLC) has to send a data frame of 18 words to the Sensor. All bytes must be transmitted
in binary format (us, MSB). The meaning of the parameters is described in the software manual.
Info: 1 word = 2 bytes
Method:
The hardware is permanently reading (polling) the incoming byte at the RS232 connection. If the incoming word is
0x0055 (synch-word), then the 2. word (order-word) is read in, after this, 16 words (parameters) will be read.
After reading in the completely data frame, the Sensor executes the order which is coded at the 2. word (order-
word).
