8 Application Instructions API 100-149 Remarks: 1. The activation criteria placed before the three instructions, API 100 MODRD, API 105 RDST and API 150 MODRW (Function Code 03), cannot use rising-edge contacts (LDP, ANDP ORP) and falling-edge contacts (LDF, ANDF, ORF); otherwise, the data stores in the receiving registers will be incorrect. 2. For the registers for flag settings, see explanations in API 80 RS. 3. There is no limitation on the times of using this instruction in the program, but only one instruction is allowed to be executed at a time.
DVP-PLC Application Manual 8-14 Feedback Explanation Data storage Nn = “03” Running instruction ‘A’ = ‘0’ Stop, ‘5’ JOG (forward) ‘1’ Forward running ‘6’ JOG (reverse) ‘2’ Stop, ‘7’ JOG (reverse) ‘3’ Reverse running ‘8’ Abnormal ‘4’ JOG (forward), ES series PLCs will convert the ASCII characters of “A” into a numeral and store the numeral in D1051. For example, assume “A” = “3”, PLC will convert A into K3 and store it in the special register D1051. SA/EH series PLCs will store the numeral in low bytes of D1051.

SA/EH series PLCs will store “B” (in hex) in the high bytes of special register D1051.
“CD” = “00” No abnormal record “10” OcA “01” oc “11” Ocd “02” ov “12” Ocn “03” oH “13” GFF “04” oL “14” Lv “05” oL1 “15” Lv1 “06” EF “16” cF2 “07” cF1 “17” bb “08” cF3 “18” oL2 “09” HPF “19” ES/SA/EH series PLCs will convert the ASCII characters of “CD” into a numerals and store the numeral in D1052. For example, assume “CD” = “16”, PLC will convert CD into K16 and store it in the special register D1052.
