On the flip side, Siemens offers a lot of options to program and customise the process to suit your business model.Īs for the pricing aspects, Allen Bradley definitely is more expensive when compared to the Siemens PLC.
Siemens might be a little complex for the maintenance staff that may not have a programming background.

It also has excellent features like communicative abilities with third party hardware, mass production of code and even export and import of tags from Excel to scada databases.

Īt the same time, Siemens uses European native IPs such as Profibus and ASI and also serial MODBUS or MODBUS TCP/IP.Ĭoming to the interface and ease of use, AB has a more intuitive and easier user interface and it allows users to manage and control their processes even without a lot of programming knowledge. AB uses mostly native American IPs such as DeviceNet, ControlNet and EthernetIP, and also the DH+ or DH485.

Also, you might need to install additional safety communication ports for Rockwell while Siemens already comes with built-in communication ports.Īnother major difference is in the protocols they use.
While the Allen Bradley requires you to connect the PLC to both the Allen Bradley power supply as well as the Allen Bradley rack, the Siemens one works with pretty much any 24 V DC supply of power. The difference lies in their installation processes. Both the AB and the Siemens PLCs work pretty much the same way and are equally reliable. It helps enhance the processes while at the same time allowing you to switch up, replicate or change the processes as well quite easily.įirst things first, the quality and functionality of the hardware are significantly distinct. In the simplest of terms, a Programmable Logic Controller or PLC is an industrial computer control system that allows you to get the most out of industrial processes. So here is a detailed comparison between the Allen Bradley and Siemens PLCs.īefore we begin, a quick word about what a PLC is. While each of these are established and top notch companies who have already proved the worth of their super-efficient TLCs individually, there has forever been a debate over which of these is better. There are predominantly two giants who have had the duopoly in the manufacture of efficient PLCs for a long time now and they are Siemens and Allen Bradley. We are talking about the invention of the Programmable Logic Controller (PLC) by Dick Morely back in 1969.Įver since then, there have been many innovations in terms of functionality and hardware features for the control system and needless to say, each new one has been tough to beat. One of the biggest boons that the industrial sector of the world at large received came in the last century.
