It should be pretty straightforward, but I'll mention one thing. There are 2 types of uploads/downloads in DirectSOFT. One transfers JUST the program logic, while the other transfer the program logic AND all of the variable values (what DirectSOFT calls a 'project'). If you want to basically 'clone' the PLC, then you want to do the latter.
Also, you said "
upload it to another Direct Logic DL-240". Uploading means
FROM the PLC
TO your computer, and downloading means
FROM your computer
TO the PLC. Make sure you know which way your going. Downloading a blank program to your 'already programmed' PLC will ruin your day quickly!
Uploading FROM the PLC TO your computer:
To upload ONLY the logic, select 'File--> Read Program--> from PLC
To upload the logic AND variables, select 'File--> Save Project--> to Disk
Downloading FROM your computer TO the PLC:
To download ONLY the logic, select 'File--> Write Program--> to PLC
To upload the logic AND variables, select 'File--> Save Project--> to PLC
Oh, and welcome to the forum!... :site:
