*1Before use variables in BLUE, it must be necessary to import variables and exported by the engineering tool. |
When setting the Modbus address, an error will
occur in the following cases:
- When the range of 408961-408969 is specified for the word address.
- When a variable of 32-bit or String data type that uses two consecutive
words is specified for consecutive addresses.
When the variable settings of the CSV editor
and the connected device are different, an error will occur.
To resolve the error, import the variable again.
When EEPROM parameters or status variables
are overused, or BIOS parameters are used, HMI startup will become
slower.
For faster HMI start up, Export only the necessary parameters,
or reduce the number of variables to use.
When Recalc has not been executed, or BIOS
parameters are used, HMI operation will become slower.
To make the operation faster, perform one of the following actions:
- Use the Recalc function for EPROM parameters and status variables
- Update the variable definition
- Do not use BIOS parameters if unnecessary
