2.	CR#1: Used to set the working mode of four channels (CH1~CH4). There are 2 modes (J-type
	and K-type) for each channel and can be set individually. For example, If you want to set
	CH1~CH4 as following: CH1: mode 0 (b2~b0=000), CH2: mode 1(b5~b3=001), CH3: mode
	0(b8~b6=000) and CH4: mode 1(b11~b9=001), you should set CR#1 to H0208. The higher
	bits (b12~b15) will be reserved and the factory setting is H0000.
3.	CR#2 ~ CR#5: Used to set the times of input readings for the average temperature calculation.
	The available range is K1~K4096 and factory setting is K10. (Note: When PLC sets average
	times via TO/DTO instructions, please use rising-edge/falling-edge detection instruction (such
	as LDP and LDF) to get correct average times.)
4.	CR#6 ~ CR#9: The average temperature (°C). The average temperature is calculated from
	multiple temperature readings. Example: If CR#2 is 10, the temperature in CR#6 will be the

Command m1: the number for special module. m2: the number of CR (Control Register) of special Explanation module that will be read. D: the location to save reading data. n: the data number of

reading one time.

DVP-series PLC uses this instruction to read CR data of special module.

D: When assigning bit operand, K1~K4 can be used for 16-bit and K5~K8 can be used for 32-bit.

In SS series models, flag M1083 is not provided. When FROM/TO instruction is executed, all interrupts (including external or internal interrupt subroutines) will be disabled. All interrupts will be executed after FROM/TO instruction is completed. Besides, FROM/TO instruction also can be executed in the interrupt subroutine.

Flag: When M1083=On, it allows to insert interrupt during FROM/TO.

Refer to following for detail.

1.When M1083=Off, FROM/TO instruction is executed, all interrupts (including external or internal interrupt subroutines) will be disabled. All interrupts will be executed after FROM/TO instruction is completed. Besides, FROM/TO instruction also can be executed in the interrupt subroutine.

2.When M1083=On, if an interrupt occurs while FROM/TO instruction has been programmed, FROM/TO instruction will be interruptted to execute the interrupt. However, FROM/TO instruction cannot be executed in the interrupt subroutine.
