Posting Data to the Device Each of the four Data View pages has the option for user updates to
the attached device using 500CPU/SLC-type write messages. Each of
these pages protects data using a unique, case-sensitive password
containing a maximum of 8 characters. You must enter the correct
password to enable device update.
Setting Passwords for Data View Pages
Passwords for the Data View pages are configured using 485CIF string
writes to elements of Node 200, as listed in Table 7.4.
For SLC or MicroLogix 485CIF Write MSG instruction, enter the offset
value in decimal. For Logix PLC-2 Unprotected Write MSG instruction,
enter the element value in octal.
A page’s password can configure the ENIW to disable device update
or to remove the password protection. To disable device update, enter
a null string in the password field. To allow device update, enter a
case-sensitive string of one to eight characters in the password field.
To permit widespread access, use a ‘*’ password.
Passwords may also be configured from the ENI/ENIW Configuration
Utility.
Posting Data
Values entered in column three of the Data View pages are written by
the ENIW to the attached device once you’ve entered the password
after displaying the page and clicking on the Write to Device button.
The ENIW writes one value at a time to the data table addresses
shown in the table below. (Multiple values are not combined into one
SLC type Write message). The Data Table addresses are also reflected
in column four of each user page.
