Display Variables
Numeric Variable Displays shows the current value at a specific
controller address: binary, BCD or signed/unsigned integer. Scaling
(y = mx + b) may be used.
ASCII Variable Displays present status information to the terminal
operator according to the current character array at a specific
controller address.
Entry Variables
Numeric Variable Entries may be used in applications designed for
MessageView 421N and 421F terminals. These variables allow the
terminal operator to enter a numeric value from the terminal keypad.
Scaling (y = mx + b) may be used.
ASCII Variable Entries may be used in applications designed for
MessageView 421D, 421N and 421F terminals if the terminal
firmware can support these variables. These variables allow the
terminal operator to enter ASCII characters from an ASCII Input
device via the RS-232 port, or via the numeric keypad on the
terminal.
Graphics
Graphics consist of a set of 32 ISA symbols illustrating
manufacturing components such as motors and containers.
