3.3.3 Low speed execution type program
The following timing charts show the operations performed when low speed execution
type programs are executed under the conditions given below.
• Constant scan time : 8ms
• Total execution time of scan execution type programs : 4 to 5ms
• Execution time of low speed execution type program A : 1ms
• Execution time of low speed execution type program B : 3ms
• END processing/low speed END processing : 0ms (assumed to be 0ms for easy
understanding)
