General Serial Communication Commands
This section provides general serial communication commands. Program-
ming commands and Factory setup commands are provided later in this
chapter. Normally, you will use these general serial communications com-
mands.
Read Number (F)
This command allows you to read the value of a variable stored in the
Series 2000 Controller. The data section of this command is a number from
00-FF. These numbers correspond to the type of variable you want to read.
The Variable Table shown in Table B-1 provides a list of these variables and
their location codes. If a variable is selected beyond the end of the Variable
Table shown, an error will be returned. The value returned is followed by
a text string for the units, where applicable.
Example:
Request Oxygen with the following string: >>FEF0536<CR>
Returned string : A20.9 %O2D4
Write Number (H)
This command allows you to set a value at the Series 2000 controller. The
data section of this command is a two digit hex number (00-FF) to point
to the location to write from the variable table (see Table B-1), followed by
the value of the variable. A simple acknowledge is returned if the com-
mand was accepted.

Use this command to start an automatic calibration or verify cycle. The
data section is either:
0 - Calibrate
