Specifications of character string data specified by link dedicated instructions
Some operands specified in link dedicated instructions are specified in character strings. The following table summarizes the
specifications of character string data specified.

Specifications of character string data
GP.READ

■
Specification method
Specify a character string by enclosing it in single quotes (').
■
Specifiable device types
• Word device: D, W, SW, SD, T, C, ST, ZR, R
• Nibble-specified bit device: X, Y, M, L, B, F, SB, SM
■
ASCII string specifications
• An ASCII string can consist of a maximum of 32 characters. (Specify NULL as the termination character.)
• ASCII strings are zero-suppressed. (Example: D1 and D001 are handled the same.)
• ASCII strings are case-sensitive.
■
Precautions
Nibble-specified bit devices can be specified only when the following conditions are all satisfied.
• The device number is a multiple of 16 (10H).
• The number of specified nibbles is 4 (K4).
An instruction specifying bit devices by nibble can be executed only when the target station is FX5CPU, RCPU, basic
model QCPU, universal model QCPU, or LCPU. If an instruction uses nibble specification for other types of CPU modules,
an abnormal response is returned from the target station and the instruction is completed with an error. (The network
module does not detect an error during execution of the instruction.)
The target device of an instruction executed in index modification mode is determined by the value of the index register of
the own station.
