matching compiler, final reoccupy special machine (read-write) special one-on-one to send the PLC program, during the system debugging, and debugging cost a huge increase in debugging time, And extremely
detrimental to future maintenance. The control accuracy is far from the same. This determines why in large and medium-sized control projects (more than 500 points), basically do not use all the PLC connected to the system. 
7. Module: All I/O modules of DCS system are equipped with CPU, which can realize the quality judgment and scalar transformation of the acquisition and output signal, plug and remove the fault with power, and replace it randomly. The PLC module is just a simple electrical conversion unit without intelligent chip, and the corresponding units are all paralyzed after failure.
8. Now the functions of high-end PLC and DCS have been almost the same, DCS network and distributed database also has a strong function of timing scanning, at the same time, the operation and simulation of the amount of the amount of more skilled.
