X20 PLC
This page is used for reviewing the status of the touch-screen and the PLC within the main
blender panel.
The PLC rack consists of a number of addressable slots where each slot has a pre-defined
X20 slice installed. The X20 PLC slices are composed of essentially three pieces, a back-
plane socket, an I/O module, and a 12 position connector. The slice, or Slot, addresses and
parts can be seen on the electrical print for the specific model blender. All three pieces plug
into each other to provide a ‘slice’ (slot). Each slice is assigned a ‘slot/slice’ number. Slices
are then connected to each other to form a rack. Slice numbers are assigned consecutively
from a ‘start’ point. Some backplane modules have Hex encoded rotary dipswitches in them.
These modules are used as ‘start’ points to begin the slot numbering scheme. Slot/slice num-
bers are Hex dipswitch settings are shown on the electrical enclosure drawing supplied with
the system.
The X20 slice provides the IO required by the system. The configuration of the system
determines the required IO and also the required X20 slices. Therefore not all of the X20
slices may be installed, and gaps in the PLC rack slot addressing may appear. The PLC rack
is powered by two sources of power. The main bus power provides power to the slice pro-
cessing hardware. The IO bus power provides the power to drive the IO points. Power
through the PLC rack may be isolated at certain points, refer to the system schematic draw-
ings for proper power connections.
Blender:
This section will present diagnostic information regarding the PLC IO rack con-
nected with the touch-screen system.
Panel:
This section will present diagnostic information regarding the touch-screen system.
Blender
The Blender screen shows the physical PLC rack hardware status. For each slice in the PLC
rack, a graphical image is shown. Each graphic shows the slot address, the type of slice
installed, and its status. By touching the slice graphic, or the slices (Type) button, detailed
information about the slice will be shown.
Information for only seven slots can be shown on a single screen. To see additional slots, a
scroll bar is provided which can be adjusted to show additional slots. Gaps in the slot
addressing may occur if the current system configuration does not require the pre-defined
X20 slice.
