6.8    Setting Security for Projects 

This section explains how to set security for projects to protect the projects and the 

data in the projects. 

Setting security restricts accesses to projects. 

Also, setting security prevents data such as POUs, device comments, and 

parameters, which are created by the user, from erroneous modifications or 

disclosures to unauthorized users. 

 

POINT 

 

 

Access levels and access authority 
Setting an access level to each user restricts accesses to each data. 
An access level is an operating authority given to a login user of the project. 
The following five levels are available as the access levels. Data that can be edited by 
a user having lower access level can also be edited by a user having higher access 
level. 

 

Higher

Lower

Administrators

<Administrator level>
All operations are possible.

Developers (Level 3)

<Developer level>
Security setting, data access, and a part of operations are restricted.

Developers (Level 2)

Developers (Level 1)

Users

<Operator level>
Only access to project data is possible.
Data cannot be read from the programmable controller CPU.

 

 

<Example> 
The data with access authority of Developers(Level 2) can be edited by login users 
with the access level of Developers(Level 2) or higher (Administrators, 
Developers(Level 3), or Developers(Level 2)).
