Logic Calculator FCMs
This section describes the active runtime fields on the following logic calculator
FCM templets. See
Common Calculator FCM Fields on page 256 for common
fields.
• Logical AND
• Logical OR
• Logical NOT
• Exclusive OR
• Set/Reset Flip-Flop
• Real Compare (Signal Comparison)
Logical AND
The Logical AND FCM performs the AND function on up to 4 inputs.
LOGICAL/BITWISE Field
Logical If all the defined inputs are not 0, Result = 1. If any of the defined
inputs is 0, Result = 0
BIT Bits 1 of all inputs are ANDed together to get Bit 1 of the result.
Bits 2 are ANDed together, and so on. The result is a decimal
number equivalent to the bit pattern resulting from the ANDing.
Bits in the inputs are shifted to the right or left prior to ANDing.
The inputs for bitwise type of FCM are decimal numbers
translated into bit patterns by the FCM. For example, an input of 9
means that bits 0 and 4 are 1 and the rest of the bits are 0.
SHIFT COUNT 1 through 4 Fields
These fields specify how many places the input bits are shifted. SHIFT COUNT 1 is
for input 1, and so on. These fields are used when LOGICAL/BITWISE is
BITWISE. Valid entries are integer values between 0 and 16.
