Operands:
m 1 : 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.
2. Range of m 1 : ES2/EX2/SS2: 0 ~ 7; SA2/SE/SX2: 0~107.
3. Range of m 2 : 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 - m 2 ) 1~(499 - m 2 )
32-bit instruction 1~2 1~(49 - m 2 )/2 1~(499 - m 2 )/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.
