AH500 Programming Manual The PLC sends the data. LRC CHK (01) above is the error checking code. It can be calculated by means of the instruction LRC. (8-bit mode: SM606 is ON.) LRC check code: 16#01+16#03+16#21+16#01+16#00+16#06=16#2C The two’s complement of 16#2C is 16#D4. ‘D’ (16#44) is stored in the low 8-bit in D113, and ‘4’ (16#34) is stored in the low 8-bit in D114. Additional remark: 1. The format of the communication data in the ASCII mode: 6-412 Register Data Description D100 Low 8 bits ‘：’ 16#3A STX D101 Low 8 bits ‘0’ 16#30 ADR 1 AD (1, 0) is the station address of the AC motor drive. D102 Low 8 bits ‘1’ 16#31 ADR 0 D103 Low 8 bits ‘0’ 16#30 CMD 1 CMD (10) is the command code.
