Where Is The Signal Of Dmxxxx Come From

[easyhumanjon 0]

Please help me.... I am using the Omron CPM2A PLC. what is the structure of DMxxxx (each one of them can store how many data, can those data be some letters?) what is it application (Mostly use with which functions)? how can I transfer some data (letters or numbers) into DMxxxx (i.e. DM0001)? and can it be put into some value after some execution?

If you havent got it yet - use the MOV(21) function You can move in hex numbers (preceeed number with #) or move the contents of another address into there. or you can use it to store the result of any mathmatical function - ADD MUL DIV etc the funtion for example can add the contents of DM0001 and DM0003 and put the result in DM0004 look up the reference for the functions when you call them up Peter
