Precautions - Mitsubishi Electric GOT 1000 Series Manual

6.12 Precautions

Precautions for the MES interface function setting are described below.
(1) When adding, editing or deleting a MES interface setting
Adding a new MES interface setting, or editing or deleting an existing one is performed on the MES interface
function setting screen.
To newly add, edit or delete a MES interface setting, have the MES interface function setting screen displayed
on GT Designer3.
(2) When deleting an item
Deleting an item such as [Device tag settings] is not allowed when the selected item is used for another item
such as [Job settings].
As the error dialog box appears, identify the location, stop using it for another item, and then delete the item.
Up to ten locations of usage are displayed in the error dialog box.
If the item is used in 11 other items or more, the dialog box is displayed as shown below.
(3) Type mismatch
(a) Value substitution
A value is assigned to a tag component after the type of the source is converted into the type of the tag
component.
A value is assigned to a variable after the type of the variable is converted into the type of the substitution
source.
(Example) Type conversion of tag components and variables
If a type that cannot be converted is assigned to a tag component, the job execution is canceled.
At this time, "Type conversion to tag component error" is displayed in the MES interface Execute Log.
6 - 98 6.12 Precautions
Because the operation result is out of the range for the integer type,
the variable Temp1 is the floating-point type.
A value is assigned after being converted to the type for the tag component.
For example, when the tag component, Data1, is double-precision type data,
the type of the variable, Temp1, is converted from floating-point to
double-precision first, and then the converted value is assigned.
