Variable Types (Offset: +3, +5, ... , +23, and +25)
Use the following equation to calculate the offset for a given variable number:
Offset = 1 + (2
× variable number)
Variable Addresses (Offset: +4, +6, ... , +24, and +26)
Use the following equation to calculate the offset for a given variable number:
Offset = 2 + (2
× variable number)
Write Variable Type Area
(27 words max.)
When CompoWay/F has been specified as the component communications
protocol, this “write variable type area” contains the variable type and variable
address settings for the SVs that will be written.
Number of Write Items (Offset: +0)
Range Function
00C0 to 00CF
(Hex)
Sets the type of variable data that you want to read.
The variable types are predetermined in each component, so refer
to the component’s manual to find the actual variable type.
A syntax error will occur if the variable type specified in this word is
not between 00C0 and 00CF Hex.
Range Function
0000 to FFFF
(Hex)
Sets the variable address of the data that you want to read.
The variable addresses are predetermined in each component, so
refer to the component’s manual to find the actual variable
address.

(BCD)
Specify the number of variables that you want to write.
For example, the variables set in variable 1 type and variable 2
type will be written if the “number of write items” is set to 0002.
Variables will not be written if the “number of write items” is set to
0000; in this case, only the operation command is valid.
A syntax error will occur if the number of items specified in this
word is not between 0000 and 0012 BCD.
