This instruction is the initial step instruction from where the step control of each machine process can be derived. Up to 8
initial steps can be used in the FBs series, i.e. a PLC can make up to 8 process controls simultaneously. Each step
process can operate independently or generate results for the reference of other processes.
【Example 1】 Go to the initial step S0 after each start (ON)
