Note
Only a user with privileges to modify variables can write data to the CPU. The Web server
ignores the commands if
the user does not have modify privileges.
If a tag name or data block name includes special characters, you must use additional
quotation marks or escape characters as described in the topic "Handling tag names that
contain special characters (Page 1055)".
