Operands:

m1: No. of special module m2: CR# in special module to be written

S: Data to be written in CR

n: Number of data to be written at a time

Explanations:

1.PLC uses this instruction to write data into CR (Control register) on special modules.

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

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

4.Setting 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.Use 32-bit instruction DTO to write the content in D11 and D10 into CR#13 and CR#12 of special module No.0. One 32-bit data is written at a time (n = 1)

2.When X0 = ON, the instruction executes; when X0 = OFF, the previous content in D10 and D11 won’t be changed.

The rules for operand:

1.m1: number of special module. The modules are numbered from 0 (closest to MPU) to 7 automatically by their distance from MPU. Maximum 8 modules are allowed to connect to MPU and will not occupy any digital I/O points

2.m2: number of CR (Control Register). CR is the 16-bit memory built in the special module for control or monitor purpose, numbering in decimal. All operation status and settings of the special module are recorded in the CR.

3.FROM/TO instruction reads/writes 1 CR at a time. DFROM/DTO instruction reads/writes 2 CRs at a time.
