Operands:

: No. of special module m
2
: CR# in special module to be read D: Device for storing read
data n: Number of data to be read at a time
Explanations:
1. PLC uses this instruction to read CR (Control register) data from special modules and built-in
network communication ports.
2. Operand ranges for m1, m2, and n:
ES2/EX2/ES2-C/ES2-E:
Operand m1 m2
n in the 16-bit
instruction
n in the 32-bit
instruction
Right-side module 0~7 0~255
1~4,
1~6 (V3.0 and above)
1~2,
1~3 (V3.0 and above)
Built-in network
communication port
(for ES2-E only)
108 0~255 1~(256-m2)
NOT recommended
SA2/SX2:
Operand m1 m2
n in the 16-bit
instruction
n in the 32-bit
instruction
Right-side module
0~7
0~48
1~6*

Left-side module
(for 12SA2/20SX2)

0~255 1~(256-m2) 1~(256-m2)/2
* The maximum number of values which can be read by SA2 V2.6/SX2 V2.4 (below) is 4 (16-bit
instruction/2 (32-bit instruction).
