Operands:

m1: No. of special module

m2: 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.

2.Range of m1: ES2/EX2/SS2: 0 ~ 7; SA2/SE/SX2: 0~107.

3.Range of m2: ES2/EX2: 0 ~ 255; SS2: 0~48; SA2/SE/SX2: 0~499.

4.Range of n:.

Range of n	ES2/EX2	SS2	SA2/SE/SX2
16-bit instruction	1~4	1~(49 - m2)	1~(499 - m2)
32-bit instruction	1~2	1~(49 - m2)/2	1~(499 - m2)/2

Program Example:

1.Read out the data in CR#29 of special module N0.0 to register D0 in PLC, and CR#30 of special module No.0 to register D1 in PLC. 2 consecutive 16-bit data are read at one time (n = 2).

2.When X0 = ON, the instruction executes; when X0 = OFF, the previous content in D0 and D1 won’t be changed.
