Processing details
■BCD
• Converts BIN data (0 to 9999) at the device designated by (S) to BCD data, and stores it at the device designated by (D).
■DBCD
• Converts BIN data (0 to 99999999) at the device designated by (S) to BCD data, and stores it at the device designated by
(D).
(S): BIN data or head number of the devices where the BIN data is stored (BIN 16/32 bits)
(D): Head number of the devices where BCD data will be stored (BCD 4/8 digits)
