FLN4234A CPU3680 Processor Modules

FLN4234A CPU3680 signal status and status table can be displayed at the same time using multiple windows that can be opened at the same time. So the elevator control system based on S7-200CN PLC is a networked, intelligent, cost-effective control system.

The FLN4234A CPU3680 integrates 24 digital I/O points with 14 inputs/10 outputs, and can be connected to 7 expansion modules. It can be connected with 7 expansion modules, the maximum expansion to 168 digital I/O points or 35 analog I/O points. 13K bytes of program and data storage space. 6 independent 30kHz high-speed counters, two independent 20kHz high-speed pulse outputs, with a PID controller, and 1 RS-485 communication/programming port. It is a controller with strong control ability.

An important reason for the FLN4234A CPU3680 to place the control center on top of the car is that most of the elevator’s signals are concentrated on the car, which can be sent directly to the control center in parallel, which is a very economical and feasible way. So obviously the number of CPU224 native I/O points can not meet the requirements, must be extended (EM223) to make up for the lack of points.
