Welcome to the PLCTalk user forum community !
Do you have a specific question about HIM Copycat ?
In general, you use it to save all the parameters from a drive into the keypad Human Interface Module (HIM) device.
Then you plug that HIM module into a new drive, and use the menus to reverse the process and copy the parameter set from the HIM to the drive.
That allows you to copy all the parameters from one drive to the another, without using software tools or manually setting up each parameter.
