View - Local Registers
Displays contents of local registers.
All the local registers (1 to 2048) can be viewed by selecting the PageUp or PageDown buttons or by
jumping to the relevant register by selecting the GotoReg button. Any local register can also be written to by
selecting the register button and entering a value.
Allows the default display format to be changed as detailed below. Note: selecting Hex or
Binary will display registers in hexadecimal format when viewing ladder logic in Debug mode.
Unsigned: (0 to 65535) Raw 16-bit integer numbers.
Signed: (-32768 to +32767) Signed 15-bit numbers. If channel 16
is ON, the number is negative.
Hex: (0 to FFFF Hex) Hexadecimal numbers.
Binary: (! = ON, : = OFF) Displays the state of each bit. Right-
most bit (LSB) is channel 1, left-most bit (MSB) is channel 16.
Float: (3.4x10
-38
to 3.4x10
38
) Signed 32-bit numbers. To be able to
store numbers of this size, the RTU stores floating point numbers
in 2 consecutive local registers and so only odd numbered float
registers are displayed. Eg. #F5 uses #R5 and #R6 while #F7 uses
#R7 and #R8. Float numbers can be entered as a signed decimal
number or by using the exponential format yX.XXXXeyZZ where
X.XXXX is the number, y is the sign (+ or -) and ZZ is the
exponential power.
Long: (-2,147,483,648 to 2,147,483,647) Signed 32-bit numbers.
Like float numbers, long numbers use two consecutive local
registers and so only odd numbered long registers are displayed.
Eg. #L5 uses #R5 and #R6 while #L7 uses #R7 and #R8.
ASCII: Displays ASCII characters (A-Z, a-z, 0-9, ( ) + - < > etc).
Allows strings to be viewed that have been copied to local registers
using the String Copy block. Two 8-bit ASCII characters can be
stored in one local register. The high byte (Channels 9-16) is
displayed as the right character and the low byte (channels 1-8) is
displayed as the left character. Eg. if #R1 contains 464B Hex, this
will be displayed as KF (K=4B Hex and F=46 Hex).
