The level 1 code (Figure 3
–14, 1234) will allow data and configuration values to be
read but not altered. The level 2 code (in the above screenshot, 5678) will allow
full access to read and write.
These security codes must be entered into PCCU32 and WinCCU32 to provide
the appropriate access to the meters. However, WinCCU32 will always need the
proper security code, regardless of the position of the security switch (S2). Turning
the security switch off does not allow unprotected access for a WinCCU32
operator.
Modbus access to the meters is not protected by the security
codes.
3.4.1.2
PCCU32 software security
PCCU32 will require the appropriate security code to be entered.
1) To enter the security code, the user will need to move to System Setup in
PCCU32.
2) Enter the appropriate security code and select Close.
In the provided example (see Figure 3
–15), the operator has been provided with
read only access to the meter.
The security code level of 1234 (per Figure 3-15) provides read only access to the
meter. If 5678 was entered, the user would have full read/write access to the
meter.
If the security level is breached, the meter will give no
indication. Any data that the user attempted to change will
simply remain unchanged.
