The variable type is converted to 2-byte ASCII and loaded to the frame. The following table shows the
available variable types.
Note: Setup area 1 has no read-only parameters, so there is no variable type “C2.”
The following table summarizes setup areas 0 and 1.
The type code depends on the parameter. Refer to 3-1 Variable Area (Setting Range) List for details.
An address is appended to each of the variable types. Express addresses in 2-byte hexadecimal and
append them for the specified access size. The address depends on the parameter. Refer to 3-1 Vari-
able Area (Setting Range) List for details.
The number of elements is expressed in 2-byte hexadecimal. The range that can be specified for the
number of elements depends on the command. Refer to 2-3 Detailed Description of the Services for
details.
Note: No commands will be accepted and no responses will be returned when a memory error (RAM error) has
occurred or the Controller is initializing (until the Controller recognizes the process value after the power is
turned ON).
Variable type Description
C0/80 R/O (read only) parameter for setup area 0.
C1/81 R/W parameter for setup area 0.
C3/83 R/W parameter for setup area 1.
C4/84 R/W parameters for setup area 0 (program setting level, currently selected number).
C5/85 R/W parameter for setup area 0.
C9/89 R/W parameter for setup area 1.
DA/9A R/W parameters for setup area 0 (program setting level, all).
Area Description
Setup area 0 This area groups together the protect, manual control, operation, program setting,
adjustment, and PID setting levels.
Setting area 1 This area groups together the initial setting, communications setting, advanced
function setting, and calibration levels.
