Addresses; Number Of Elements; List Of Services (Main Request Codes And Sub-Request Codes) - Omron E5C-T Series Communications Manual

The variable type is converted to 2-byte ASCII and loaded to the frame. The following table shows the
available variable types.
Variable type
C0/80
C1/81
C3/83
C4/84
C5/85
C9/89
DA/9A
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.
Area
Setup area 0
Setting area 1
The type code depends on the parameter. Refer to 3-1 Variable Area (Setting Range) List for details.

Addresses

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.
2-2-5

Number of Elements

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
