Ethernet PLC CPU226


The Amsamotion Ethernet PLC CPU226 supports the Siemens WinCC S7 protocol, which is a communication protocol for industrial automation and process control systems. This means that the CPU226 can communicate and interact with other devices and systems that use the S7 protocol, allowing for seamless integration and exchange of data in an industrial setting.



The CPU226 is a programmable logic controller (PLC) made by Siemens. It is part of the S7-200 series of PLCs, which are designed for small-scale automation applications. The CPU226 model has an Ethernet port, which allows it to communicate with other devices over a network. It also has 24 inputs, 16 outputs, 2 analog inputs, and 1 analog output. PLCs are used to control industrial machines and processes, and they are programmed using a specialized programming language. The CPU226 can be used to replace an existing Siemens S7-200 PLC, or it can be used in a new automation application

AMX-216-3BD23-0XB8 Relay Type PLC Ethernet Version

To replace a Siemens S7-200 PLC with Ethernet connectivity, you could consider using the AMX-CPU226xp. This is an industrial programmable logic controller (PLC) that features Ethernet connectivity and can communicate using standard industrial protocols such as TCP/IP, Modbus TCP, and Profinet. It has a compact design and supports a wide range of I/O and communication modules, making it a versatile and flexible solution for your automation needs.

Q: What is PWM and What is PTO??

A: PWM belongs to analog control mode, when the equipment has the exact requirements for rotational speed and torque we can choose PWM. PWM will simulate the input signal as constant voltage output by applying a high-speed counter, it controls the variation of motor rotational speed by controlling voltage variation.
