At present, is there any similar or highly imitated Siemens 1500 series plc in China?

It is not recommended to use domestic plc. Unless the equipment is only used for auxiliary purposes, most domestic PLCs either imitate Siemens s7-200 or Mitsubishi fx. Honestly, it's not pretty. At least, it's not worth buying a smart company that always steals from others. And now the genuine PLC is cheaper and more cost-effective. How much can it cost to choose a cpu? For me, there is absolutely no need to steal the company's products, even if I spend more money and earn less profit.
