ABB CI854AK01 3BSE030220R1 PLC controller
The PLC programmable control system mainly consists of input part, CPU, sampling part, output control and communication part, as shown in Figure 1. The input section includes a control panel and input templates; The sampling section includes a sampling control template, an AD conversion template, and a sensor; As the core of the system, the CPU is responsible for receiving, processing, and outputting control signals; Some systems use DA templates in the output part to convert the output signal into analog signal, which is then driven by a power amplifier to drive the actuator; Most systems directly output signals to the output template, which drives the actuator to work; The communication part consists of a communication template and an upper computer.
Because the probability of PLC failure is extremely low, system failures mainly come from peripheral components, so its failures can be divided into the following types:
Input fault, i.e. operator error;
Sensor malfunction;
Actuator malfunction;
PLC software failure
These faults can be analyzed using appropriate fault diagnosis methods and monitored in real-time using software to predict and process faults.
Fault diagnosis methods for PLC control systems
Macro diagnosis of PLC control system faults
The macroscopic diagnosis of faults is to determine the location and cause of the fault based on experience, referring to the environment and phenomenon in which the fault occurred. The macroscopic diagnosis method for faults in PLC control systems is as follows:
Is it a malfunction caused by improper use? If it belongs to this type of malfunction, the type and location of the malfunction can be preliminarily determined based on the usage situation. Common improper use includes power supply failure, terminal wiring failure, template installation failure, on-site operation failure, etc.
If it is not a malfunction, it may be caused by accidental or long-term system operation. For such faults, they can be checked and judged sequentially according to the distribution of PLC faults. Firstly, check if there are any faults in the sensors, detection switches, actuators, and loads connected to the actual process. Secondly, check if there are any faults in the I/O template of the PLC. Finally, check if there are any faults in the CPU of the PLC.
When checking for faults in the PLC itself, you can refer to the indicator lights on the CPU template and power template of the PLC.
If the fault location and cause cannot be identified by taking the above steps, it may be a system design error. At this time, the system design, including hardware and software design, needs to be rechecked.
