Operation for receive command
1
Change the trigger condition LM202 from 0 to 1 to be ready for receiving user communication.
2
Data is transmitted from the external device and the transmitted data is received and processed.
The receive data is as follows.
• The receive data is compared with the character data, and the value of the matching Index No. (10 (Dec)) is stored
in Index Device Address LDR230.
• The 2 bytes (specified with
Skip
) of the receive command data 43h and 44h are ignored.
• Since the Reference Device Address LDR 230 of
Device Address
of the receive command data is 10 (Dec), the
data is stored in the device address LDR250 and LDR251, which is offset by +10.
•
[STX] ABCD1234
is calculated with
BCC
of receive command data and compared with 3032h.
- When Calculation Start Position is 1 and Calculation End Position is 0: Calculates the range
STX ABCD1234
.
