1. The programming method of the programmable ifm controller is simple and easy to learn
Programmable ifm controller ladder diagram is the programming language of the PLC that is used more often, its circuit symbols and expressions are similar to the schematic diagram of the relay circuit, the ladder diagram language is intuitive, easy to learn and understand, and the electrical personnel who understand the relay circuit diagram need to spend a few days to understand the ladder diagram language, and use it to compile the user program of the digital control system.
2. The programmable ifm controller is small in size and low in energy consumption
After the PLC is used in the messy control system of the programmable ifm controller, the PLC control system is compared with the relay control system, the wiring consumption is small, the wiring time of the device is short, and the size of the switch cabinet is reduced, so that a lot of costs can be saved, and the volume of the small PLC is equivalent to the size of several relays, so the volume of the switch cabinet can be reduced to 1/2 - 1/10 of the original.
3. The programmable ifm controller has a small repair workload and is easy to repair
Programmable ifm controllers have a low bug rate and are fully fault-diagnostic. When there is a fault in the PLC or the external input device and actuator, the cause of the fault can be easily and quickly identified according to the information provided by the light-emitting diode or programming software on the signal module, and the fault can be eliminated quickly by changing the module.
4. The planning, commissioning and installation of the programmable ifm controller system require less work
The programmable ifm controller replaces many moment relays, counters, interrogators and other equipment in the relay control system with software functions, which greatly reduces the workload of planning, wiring and installation of the control cabinet. For the messy control system, the ladder diagram program of PLC can be planned by sequential control planning method, which is very regular and simple to grasp. In the process of on-site commissioning, the problems found can generally be solved through correction procedures, and the debugging time of the system is much less than that of the relay system.
