The S7-1500 also comes with a small graphical display which allows for troubleshooting right from the front of the PLC. The S7-1500 also comes standard with two PROFINET ports, which allows the user to separate networks and makes connecting to other devices simpler.
Siemens S7-1500 Family (click for source) The main difference between these two is the S7-1500 does not require a backplane, as it is a din rail mount system. On the larger scale Siemens offers the S7-1500, which is comparable to the ControlLogix family of controllers.
It supports a max of 1 signal expansion board (aka plug-in), 8 signal modules, and 3 communications modules, while the latest CompactLogix line, the 5380 series, can support up to 31 I/O modules (with the largest Controllers – Ed.) Image by Shawn Tierney That said, the S7-1200 is more limited in add-on modules. Siemens S7-1200 (click for source)īut the S7-1200 is actually more comparable to the CompactLogix in terms of processing power and memory. Let’s start by looking at the Controllers or CPUs of each manufacturer.įrom an Allen-Bradley programmer's perspective, at first glance a Siemens S7-1200 might look like a MicroLogix, with its small form factor and on-board I/O. So in today's article I want to share with you a comparison of these two product lines, including both the programmable controller hardware, as well as programming software. It does have the same advantage of point and click interface or via a text entry line which is very useful for advanced users.Are you an experienced controls engineer working in manufacturing or integration with an in depth knowledge of Allen-Bradley and have recently been introduced to Siemens? Image by Chris Wrightįor eleven years I've predominately with Allen-Bradley Programmable Controllers, which is not very surprising as they are the most common brand used in North America.īut recently I started working with a manufacturing company who’s equipment is all Siemens, and for the past year I've been exclusively working with the Siemens line. RSLogix 5000 has a ladder logic editor that is similar to RSLogix 5 and RSLogix 5000, which make the migration very easy and natural.I/O addressing is very simple specially when using aliasing that connects tags to input and output signals.This is really a big leap in how data is handled. It also includes a very sophisticated data handling such as arrays, user defined structure, which brings a tremendous flexibility to the way data is manipulated and worked with.The controller configuration, Tasks, Motion groups, Trends Data types and I/O configuration. Control Organizer that is an explorer like window that shows all the different parts of the program.
RSLogix 5000 software functionality includes: RSLogix 5000 is compatible with programs created with any of Rockwell Softwares DOS-based programming packages, as well as with RSLogix 5 and 500. The RSLogix 5000 package builds on the easy-to-use RSLogix 500 ladder editor to provide a programming environment that takes advantage of the features of the new architecture. This controller represents the new generation of control products from Allen-Bradley. RSLogix 5000 software supports the ControlLogix architecture, and is the programming software for the Logix1/63 controllers. KronoTech RSLogix 5000 Ladder Logic Structured Text HMI Search Contact us
