EZwarePlus Programming Manual

There are two security modes in EZwarePlus, General mode and Enhanced Security mode. General mode operates

the same as the security feature in EasyBuilder-5000, so projects created in EasyBuilder-5000 will default to the

General mode when opened in EZwarePlus. Enhanced Security mode provides additional features and user account

management for improved security and runtime editing of user accounts.

General Mode

When General mode is selected, up to 12 users can be individually enabled, and each has a unique password and

combination of any six access classes (A-F). Only numbers are allowed for passwords. When an object is created, it

can be assigned an access class. When that object is activated (for example, a button is touched), the HMI compares

the access classes allowed for the currently logged-in user to the access class specified for the object. If the access

class of the object is within the classes allowed, the object’s action is executed.

In order for a user to login, they must first enter their user number into reserved local word LW9219. Then they must

enter their password into reserved local word LW9220 (32-bit unsigned).

There are several other reserved local words and bits that can add functionality to your security implementation.

Reserved Local Memory

Function

LW9222

Displays the access levels assigned to the currently logged-in

user in binary format (16-bit binary)

Bit 0: A, Bit 1: B, Bit 2: C, Bit 3: D, Bit 4: E, Bit 5: F

LW9500-LW9523 (32-bit unsigned)

Stores user passwords 1-12

LB9050

Logs out user and resets password to zero when bit is set (HMI

resets bit to zero)

LB9060

Indicates when an invalid password has been entered (bit

resets to zero when valid password is entered)

LB9061

Set to update user passwords when changed locally

(LW9500-LW9523) Use momentary style

Refer to the Security Sample Project on our website to see how to employ the above reserved local memory bits and

registers in a security implementation.
