4.1.5
Reply frame to a register value request in a downlink frame
Following reception of a downlink frame with the code 0x40, the frame 0x31 is transmitted.
It contains all the values of the registers requested in the downlink frame 0x40.
EN
Example :
•
Frame (0x40) sent to the product (downlink):
0
Code
0x40
The CONF IDX (8bits) fields represent the indices of the registers to be sent. The corresponding regis-
ter is 300 + CONF IDX value.
•
Response frame (0x31) from the product:
0
Code
0x31
In this example: CONF ID1 is a 2-byte register, CONF ID2 a 1-byte register and CONF ID3 a 2-byte
register.
If an error is detected in the request, the returned 0x31 frame will be empty.
4.1.6
Data Frame
This frame (0x46) is transmitted at the frequency defined in register S301.
0
Code
0x46
0x46
Its size is of 10 bytes.
Description of the frame:
•
Bytes 2 to 5: counter value for channel A when transmitting the frame
•
Bytes 6 to 9: counter value for channel B when transmitting the frame
In the example in grey this gives:
•
Bytes 2 to 5 : counter channel A = 0x00015C4F so 89,167 pulses
•
Bytes 6 to 9 : counter channel B = 0x0000F74A so 63,306 pulses
