SIMATIC WinAC Slot-PLC

The WinAC Slot PLCs are used when increased availability and operational safety are required in PC-based solutions.
The performance and instruction sets of the WinAC Slot PLCs are based on the powerful S7-400 CPUs and enable control independently of Windows..
WinAC Slot PLC is available in two different versions:

WinAC Slot 412 based on the CPU 412-2 with 128 KB memory for code and 128 KB memory for data
WinAC Slot 416 based on the CPU 416-2 with 1.6 MB memory for code and 1.6 MB memory for data

The Slot PLCs are capable of instruction-specific restart and continue the user program immediately from the point of interruption. Thanks to an external 24V supply, the user program of the Slot PLC can be processed completely independently of the PC.
Thanks to battery backup, all data areas can be retentive. Thanks to the rugged configuration and deterministic behavior, applications with increased availability and operational safety can be implemented.

Design
Up to four Slot PLCs (one PCI slot each) can be operated in one PC. In addition, a Software PLC can also be combined with up to three Slot PLCs. An automation solution can thus be structured more compactly with fewer PCs, thus reducing space requirements and hardware costs.
The Slot PLCs have an integral MPI/DP interface and a DP interface for communication with other CPUs and for connecting distributed I/O, for example. In addition, the Slot PLCs support the isochronous mode functionality to enable distributed solutions for high-speed, time-dependent tasks.

Functionality
Programs can be archived and dearchived via the hard disk of the PC. The WinAC Panel on the PC offers the display and operator input functions of the Slot PLC – comparable with those of an S7-CPU.
The firmware is updated immediately by downloading a file without having to store it on a memory card. Loading the firmware in the installed state from any PC memory medium (hard disk, USB stick, CD-ROM) simplifies and accelerates service and maintenance.
