Boolean Execution Times
Boolean execution times for contacts and coils depend on several factors, including the CPU model,
the type of reference address associated with the contact/coil, and whether the address is used
directly or passed as a parameter. To help compare Boolean performance across PACSystems CPUs,
average time measurements are presented below for each CPU model.
The measurements are for these three categories:
Simple address: Boolean with a simple reference address that is known at compile/validation
time. For example, a symbolic variable, or a mapped variable, such as %I00001, or a Boolean
from an array that is indexed by a constant, such as BoolArray[3].
Complex address: Boolean with a complex address that requires run-time computation to
resolve. For example, a Boolean from an array that is indexed by a variable, such
asBoolArray[j].
Passed as parameter: Boolean within a parameterized block or UDFB, where the reference
address of the Boolean is passed as a parameter to the block. The measurement covers the
Boolean execution time within the block, but does not include the time to compute the
reference address before passing it to the block.

Instruction Timing
A-2.1
Overview
The tables in this section list the execution and incremental times in microseconds (µs) for each
function supported by the PACSystems CPUs. Two execution times are shown for each instruction.
Execution Time
Description
Enabled
Time in µs required to execute the function or function block when power flows
into the function with valid inputs.
Disabled
Time in µs required to execute the function when it is not enabled.
Notes:
All times represent typical execution time. Times may vary with input and error conditions.
Enabled time is for single length units of word-oriented memory.
COMMREQ time was measured between CPU and Ethernet module with NOWAIT option.
DOIO time was measured using a discrete output module.
Timers are updated each time they are encountered in the logic by the amount of time
consumed by the last sweep.
Performance times for the BUS_ functions were measured on the RX7i using a Series 90-70
Genius Bus Controller, and on the RX3i using an RMX128 Redundancy Memory Xchange Module.
Performance times for all redundancy (CRE and CRU) CPUs were measured with ECC enabled.
Due to a change in caching, measured times for some instructions changed for release 6.0 as
compared to releases 5.0/5.1. It was found that increases in some instructions were offset by
decreases in other instructions, so that no effective net change was observed.
