Security System
The Main Electronic Board (XRC-195 Board) has a bi-level security system built in. For the
purpose of this manual, we will refer to this as the Hardware Security. When the XRC is
accessed through PCCU32 or WinCCU Host software packages, this will have a third level
of security included. We will refer to this as the Software Security.
The Hardware Security System is designed to have two levels of user access, Read (Level
1) and Read/Write (Level 2) privileges. User access by default has full Read/Write
privileges; allowing the operator to change the various operational parameters including;
orifice plate, meter run diameters, alarm limits, etc. To restrict the access, security codes
for Level 1 and Level 2 must be setup (see instructions below).
The Software Security System is designed to have a Password Administrator who sets up
the accounts and privileges for himself as well as the other PCCU32/WinCCU users. These
privileges includes being able to instantiate applications and make changes to the
functionality of the XRC, i.e. Application Editing and Downloading Files to a device. See the
help files in the host software package for more information. When connecting remotely via
WinCCU, position of the S1 Security Switch is not significant as long as WinCCU Security
Code is equal to the level of access requested. Security is always passed and checked
when using remote communications to communicate to the XRC using PCCU or WinCCU.
Additionally, the administrator may “Force Login” access by using tools available in
PCCU32 and WinCCU. See Host Software help files for additional information.
If the Security Switch S1 located on the XRC-195 Board is in the OFF
position (disabled), no security code has to be entered to access the
operating parameters via PCCU32 (locally) even if there is one
programmed into the device.
Modbus access to the meters is NOT protected by the Security System.
