7.5 Parameter Commands
Through the use of parameter commands, it is possible to refer to values of parameters and monitor ( reference
commands ), assign numerical values and variables to parameters ( simple setting commands ), and assigning
results of arithmetic operations on numerical values and variables to parameters ( calculation result setting
commands
). The response is issued immediately.
A reference command issues a transmission character string simply containing a variable given directly by #***.
At normal operation, if a response is generated, a response character string that begins from “R1
! ” and one data
is returned.
In simple setting commands and calculation result setting commands, the left-hand side must be variables
expressed by #***. The right-hand side can be direct numerical values, or it can contain variables such as a
parameter/monitor referred to by #***. The response at normal operation is “R00.”
[Reference commands]
# !
# !
Reads the value of parameter # !
Reads the value of monitor # !
Response character string: R1D ! : !
Response character string: R1B ! : 00010000
[Simple setting commands]
#400= !
#400=# !
Sets ! to variable #400.
Sets the value stored in # ! to variable # ! .
[Calculation result setting commands]
The following operands can be used:
+ Addition
- Subtraction
* Multiplication
/ Division
% Remainder at integer division
# ! = ! + !
# ! = # ! - !
# ! = ! * # !
# ! = # ! / # !
#
!
=
!
%
!
Sets the result of adding ! and ! to variable # ! .
Sets the value obtained by subtracting ! from the value stored in # ! to variable # ! .
Sets the result of multiplication of ! and the value stored in # ! to variable # ! .
Sets the value obtained by dividing the value stored in # ! by the value stored in # ! to
variable # ! .
Sets the remainder of
!
divided by
!
to variable #
!
.
