Zone control for BIN 16-bit data, zone control for BIN 32-bit data
ZONE(P), DZONE(P)
Processing details
■ZONE
• Adds bias value designated by (S1) or (S2) to input value designated by (S3), and stores at device number designated by
(D). Bias values are calculated in the following manner:
• The values that can be designated by (S1), (S2), and (S3) are in the range of from -32768 to 32767.
• The output value stored at (D) is a signed 16-bit BIN value. Therefore, if the operation results exceed the range of -32768 to
• The output value stored at (D) is a signed 16-bit BIN value. Therefore, if the operation results exceed the range of -32768 to
32767, the following will take place:
Ex.
When negative bias value is -100 and input value is -32768
-32768 + (-100) = 8000H + FF9CH = 7F9CH = 32668
-32768 + (-100) = 8000H + FF9CH = 7F9CH = 32668
(S1): Negative bias value to be added to an input value (BIN 16/32 bits)
(S2): Positive bias value to be added to an input value (BIN 16/32 bits)
(S3): Input value used for a zone control (BIN 16/32 bits)
(D): Head number of the devices where the output value controlled by the zone control will be stored (BIN 16/32 bits).
(S2): Positive bias value to be added to an input value (BIN 16/32 bits)
(S3): Input value used for a zone control (BIN 16/32 bits)
(D): Head number of the devices where the output value controlled by the zone control will be stored (BIN 16/32 bits).
