There is a program counter in the CPU of the PLC that indicates the storage address of the program step. During the program running, the counter will automatically increase by 1 after executing one step. The program will be executed from the starting step (the step number is zero) to the final step (usually the end instruction), and then return to the starting step for cyclic operation. The time required for PLC to complete each cycle operation is called a scanning cycle. For different types of PLC, the cycle scanning period is between 1 microsecond and tens of microseconds. The loop operation such as program counter is not available in DCS. This is also the reason why the redundancy of PLC is not as good as that of DCS.DCS is developed on the basis of operational amplifier. The relationships between all functions and process variables are made into functional blocks (some DCS systems are called expansion blocks). The main difference between DCs and PLC is in the logic calculation of switching value and the operation of analog value. Even though the two later infiltrated each other, they were still different.Since the 1980s, in addition to logic operation, the algorithm function of PLC control loop has been greatly enhanced. However, PLC is programmed with ladder diagram, and the operation of analog quantity is not very intuitive during programming, which is troublesome. However, in terms of solving logic, it shows the advantage of being fast. At the microsecond level, it can solve 1K logic program in less than 1 millisecond. It treats all inputs as switching values, and 16 bits (also 32 bits) are an analog value.
DCS regards all inputs as analog values, and 1 bit is the switching value. Solving a logic is on the order of hundreds of microseconds to milliseconds. For PLC, a PID calculation takes tens of milliseconds, which is about the same as that of DCS.In terms of grounding resistance, the requirement for PLC may not be high, but it must be less than several ohms (usually less than 4 ohms) for DCS. Analog isolation is also very important.
