Hello, I am using Direct Soft 6 with a DL06 PLC. I purchased the F0-08ADH-2 expansion module to take analog input readings. In the manual, it tells you how to set up the memory locations for this module. My pressure sensor is in the V2000-2001 memory location. The readings from this sensor are always changing due to various pressures within my system. I want to be able to take a pressure reading and store it as a constant for later use. How do I accomplish this? I want the sensor to be able to dynamically update within the program, but at a specific point in the program, I want to take a reading and publish a constant value to another memory location. Any wisdom? - I can't seem to find the answer I want in the user manual. Maybe it is my lack of experience with PLC's.

use whatever you want to control the when , and use either a MOVE or MOVED to copy the register into another register.

use either a MOVE or MOVED
Is that a DS6 thing? I can't find it in DS5.

MOV (for moving a group of words) is a standard instruction
MOVEW (for moving a single word) and MOVED (for moving a double word) are IBox instructions.
I don't see just 'mOVE ' as an instruction.

Thanks for your help. I tried the MOV command and it is moving the value from V2000 into another memory location. I used the V2030 memory location to move the value into. However, upon using the memory editor, both locations are dynamically updating in sync with each other. I want to be able to move the value and hold it constant within that memory location. Is there a way to do that?
Thanks.

yeah, the MOVE instruction is native in Do-More, sorry...
you will probably need a positive differential to control the when , like I stated before. If the instructions on the rung are on, then the values will constantly update.
you could try something like this....

note: I added a few different instructions & I-Boxes for a better explanation

Thanks for your help. It works! Appreciate it, I have not taken advantage of the positive differential contacts.
