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.
