Description
Overview
The program is an example of reading and writing all setup items. The following four
actions are executed.
•
Gets the setup data from the MX100 collectively.
• Retrieves the setup data of the setup data field by item.
• Writes the setup data in the setup data field by item.
• Sends the setup data to the MX100 collectively.
Each item is retrieved and written from the first number to the end number.
Be sure to prepare string fields of sufficient size.
By saving and loading groups of item numbers and item strings, you can backup the
setup data.
For setup item numbers, see section 6.3.
