By default we use software from Siemens for our PLC programming, eg Step7 and TIA for S7-300/400/1200/1500.
Smaller controllers can be programmed with S7-200 or LOGO.
Older systems with S5 PLCs, we like to modern to S7 controllers.
Another mainstay of Ataix is programming in CoDeSys for the controllers from Beckhoff and WAGO, we have executed several procects with this software.
On request we can also offer programming for Rockwell products RSLogix and RSView Intouch.
