Cycle Time and Operations
Cycle Time Example
Process
TMHH(– –) may be inaccurate when TC 000 through TC 003 or TC 008 through TC 255 are used
(operation will be normal for TC 004 through TC 007).
TIMH(15) may be inaccurate when TC 004 through TC 255 are used (operation will be normal for TC
000 through TC 003).
Programming using the 0.02-second Clock Bit (SR 25401) may be inaccurate.
TIM may be inaccurate. Programming using the 0.1-second Clock Bit (SR 25500) may be inaccurate.
A CYCLE TIME OVER error is generated (SR 25309 will turn ON).
The FALS 9F monitoring time SV is exceeded. A system error (FALS 9F) is generated, and operation
stops.
Programming using the 0.2-second Clock Bit (SR 25501) may be inaccurate.
Note
The effects of the cycle time on operations are as shown below. When a long
cycle time is affecting operation, either reduce the cycle time or improve
responsiveness with interrupt programs.
In this example, the cycle time is calculated for a Unit. The I/O is configured as
follows:
The rest of the operating conditions are assumed to be as follows:
The average processing time for a single instruction in the user’s program is
assumed to be 1.26 µs. The cycle times are as shown in the following table.
1. The CompoBus/S communications wait time can be calculated by sub-
6 inputs:
4 outputs: 1 word (01000 to 01003)
User’s program: 500 instructions (consists of only LD and OUT)
Cycle time:
tracting the time required for processes 9, 10, 11, and 1 from the Compo-
Bus/S communications response time.
CompoBus/S wait time = CompoBus/S response time – (9) – (10) – (11) –
