Overview
Mathematical
Operators
Mathematical operators can only be used in SELOGIC Math Variables; the opera-
tors are shown in Table 4.3. Use the mathematical operators with Analog Quanti-
ties (e.g., IA, IB, IC); including Math Variables (MV01–MV32). See SEL
OGIC
Control Equation Operators for more details.
Function Blocks
Function block outputs can be used in any SELOGIC equation; the function blocks
and their outputs are shown in Table 4.4. Likewise, logical operators can be used
in any of the SEL
OGIC equations that drive the function blocks. Each function
block is described in more detail in General Logic Functions.
