1、系统联机前要进行组态，即确定系统管理的I/O点数，输入寄存器、保持寄存器数、通信端口数及其参数、I/O站的匹配及其调度方法、用户占用的逻辑区大小，等等。组态一经确认，系统便按照的约束规则运行。重新组态时，按原组态的约定生成的程序将不能在新的组态下运行，否则会引起系统错乱。因此，第一次组态时要慎重，I/O站、I/O点数，寄存器数、通道端口数、用户存储空间等均要留有余地，考虑到近期的发展。但是，I/O站、I/O点数、寄存器数、端口数等的设置，都要占用的内存，同时延长扫描时间，降低运行速度。因此，余量又不能留得太多。特别要引起注意的是运行中的系统不能重新组态。
2、对于大中型PLC机来说，由于CPU对程序的扫描是分段进行的，每段程序分段扫描完毕，即更新一次I/O点的状态，因而大大提高了系统的实时性。但是，若程序分段不当，也可能引起实时性降低或运行速度减慢的问题。分段不同将显著影响程序运行的时间，特别是对于个别程序段特长的情况尤其如此。一般地说，理想的程序分段是各段程序有大致相当的长度。
