User Registers
User Registers (%T, %M and %R) are used to store application-specific Mini data. This data can be
accessed via User Screens and/or by Ladder Code.
a.
%T Register
A %T Register is a non-retentive 1-bit memory location, used to store application-specific state
information.
b.
%M Registers
A %M Register is a retentive 1-bit memory location, used to store application-specific state information.
c.
%R Registers
A %R Register is a retentive 16-bit memory location, used to store application-specific values.
HMI Registers
HMI Registers (%K and %D) give the user access to the OCS or RCS keypad and display.
The MiniOCS has a membrane keypad and text-based LCD display, allowing the operator to enter and
display general and application-specific information. This same information can be entered and displayed
for the MiniRCS (and MiniOCS if desired) via a remote PC using Cscape’s Remote Display Terminal
function.
a.
%K Registers
A %K Register is a non-retentive 1-bit memory location (contact), used to store the state of a function key
on the Control Station’s keypad. If the function keys are set for momentary mode, a function key’s
associated %K register will be ON as long as the function key is pressed. If the function keys are set for
toggle mode, a function key’s associated %K register will toggle each time the function key is pressed.
b.
%D Registers
A %D Register is a non-retentive 1-bit memory location (coil), which can be turned ON by Ladder Code to
cause the corresponding User or Alarm Screen to be displayed.
c.
User Screens
A User Screen is a combination of fixed text or graphics, along with variable Data Fields (called Graphics
Objects in the MINIOCS), which together fill the LCD display screen. These screens are defined via
Cscape dialogs and are then downloaded and stored into the Control Station’s Flash memory. User
Screens can be selected for display by operator entries on the keypad, or by Ladder Code.
d.
Data Fields
A Data Field is an area on a User Screen where variable data is displayed and edited. The source data
for a Data Field can be any of the Control Station’s Register resources as defined above. The field size
and display format is programmable via Cscape dialogs.
