Input
After setting length and group number of recipe, the user can click
button to edit the recipe data. The memory size for recipe is limited and the
memory size for recipe is 64K. It indicates that the total recipe size should be less
than 64K (The number of Length x Groups should be less than 65536). If the total
recipe size exceeds the limit, the user will see a warning message shown as Fig.
2.8.15 displayed on the screen.

The above-mentioned memory means the non-volatile memory of HMI, i.e.
SRAM. Some DOP series HMI, which supports USB host function, allows the user
to use more recipe data via this USB host interface. Supporting USB host function
means it has a built-in USB host interface. The user can connect HMI to a USB
flash drive via this USB host interface and input more recipe data. However, there
is still a limit for the input value of recipe length and groups. When Hold Data
Place is selected as USB flash drive, the length x groups should be less than
4096K (The number of Length x Groups should be less than 4194304). The user
can change the selection of Hold Data Place by clicking Options > Configuration
> Standard. Please refer to Fig. 2.8.16 on next page.
