Watlow EZ-ZONE RMC - Manual (Page 170)

Watlow EZ-ZONE ® RMC Module • 167 • Chapter 7 Features
set to 1 and [rloC] is set to 3, the available Pages
for a User without a password would be limited to
the Home and Factory Pages (locked level 1). If the
User password is entered all pages would be acces-
sible with the exception of the Setup Page as defined
by level 3 access.
How to Enable Password Security
Go to the Factory Page by holding down the Infinity
ˆ
key and the Advance
‰
key for approximately six
seconds. Once there, push the Down ¯ key one time
to get to the [`loC] menu. Again push the Advance
‰
key until the Password Enabled [pas;e] prompt
is visible. Lastly, push either the up or down key to
turn it on. Once on, 4 new prompts will appear:
1. [loC;l] , Locked Access Level (1 to 5) correspond
ing to the lockout table above.
2. [roll] , Rolling Password will change the Cus-
tomer Code every time power is cycled.
3. [pas;u] , User Password which is needed for a Us-
er to acquire access to the control.
4. [pas;a] , Administrator Password which is need-
ed to acquire administrative access to the control.
The Administrator can either change the User and
or the Administrator password or leave them in the
default state. Once Password Security is enabled they
will no longer be visible to anyone other than the
Administrator. As can be seen in the formula that
follows either the User or Administrator will need to
know what those passwords are to acquire a higher
level of access to the control. Back out of this menu
by pushing the Infinity ˆ key. Once out of the menu,
the Password Security will be enabled.
How to Acquire Access to the Control
To acquire access to any inaccessible Pages or
Menus, go to the Factory Page and enter the [UloC]
menu. Once there follow the steps below:
Note:
If Password Security (Password Enabled [pas;e]
is On) is enabled the two prompts mentioned below
in the first step will not be visible. If unknown,
call the individual or company that originally set-
up the control.
1. Acquire either the User Password [pas;u] or the
Administrator Password [pas;a].
2. Push the Advance
‰ key one time where the Code
[Code] prompt will be visible.
Note:
a. If the the Rolling Password is off push the Ad-
vance key one more time where the Password
[pass] prompt will be displayed. Proceed to
either step 7a or 8a. Pushing the Up ¿ or Down
¯ arrow keys enter either the User or Adminis-
trator Password. Once entered, push and hold
the Infinity ˆ key for two seconds to return to
the Home Page.
b. If the Rolling Password [roll] was turned on
proceed on through steps 3 - 9.
3. Assuming the Code [Code] prompt (Public Key)
is still visible on the face of the control simply
push the Advance key ‰ to proceed to the
Password [ pass] prompt. If not find your way
back to the Factory Page as described above.
4. Execute the calculation defined below (7b or 8b)
for either the User or Administrator.
5. Enter the result of the calculation in the upper
display play by using the Up ¿ and Down ¯ ar-
row keys or use EZ-ZONE Confgurator
Software.
6. Exit the Factory Page by pushing and holding the
Infinity ˆ key for two seconds.
Formulas used by the User and the Administrator to
calculate the Password follows:
Passwords equal:
7. User
a. If Rolling Password [roll] is Off, Password
[pass] equals User Password [pas;u].
b. If Rolling Password [roll] is On, Password
[pass] equals:
([pas;u] x code) Mod 929 + 70
8. Administrator
a. If Rolling Password [roll] is Off, Password
[pass] equals Administrator Password
[ pas ;a ]
.
b. If Rolling Password [roll] is On, Password
[pass] equals:
([pas;a] x code) Mod 997 + 1000
Differences Between a User Without Password,
User With Password and Administrator
- User without a password is restricted by the
Locked Access Level [loC;l].
- A User with a password is restricted by the
Read Lockout Security [rloC] never having ac-
cess to the Lock Menu [`loC].
- An Administrator is restricted according to the
Read Lockout Security [rloC] however, the Ad-
ministrator has access to the Lock Menu where
the Read Lockout can be changed.
Modbus - Using Programmable Memory
Blocks
When using the Modbus protocol, the RMC module
features a block of addresses that can be configured
by the user to provide direct access to a list of 40
user configured parameters. This allows the user
easy access to this customized list by reading from or
writing to a contiguous block of registers.
