Conversion from block BIN 16-bit data to BCD 4-digit data
BKBCD(P)
Processing details
• Converts BIN data (0 to 9999) n points from device designated by (S) to BCD, and stores result following the device
designated by (D).
Operation error
• In any of the following cases, an operation error occurs, the error flag (SM0) turns ON, and an error code is stored into SD0.
(S): Head number of the devices where BIN data is stored (BIN 16 bits)
(D): Head number of the devices where the converted BCD data will be stored (BCD 4 digits)
n:
(D): Head number of the devices where the converted BCD data will be stored (BCD 4 digits)
n:
