The Accessed Port and Authorization register is a bit-mapped word defined as
follows:
Bits Description
0 to 3 The number of the accessing port (0 for Modbus Gateway)
4 Read Authorization Waived
5 Write Authorization Waived
6 Read Access Granted
7 Write Access Granted
8 to 15 Reserved
A waived authorization means that password entry is not required for this action
even if a non-zero password has been configured. Authorization waivers are
configured separately for each port, so, for example, a SCADA system
connected to port 2 can be allowed to read measurement results without having
to supply a password while an operator connecting AFC Manager to port 1 still
must enter the correct password. The backplane is always given both waivers, so
the PLC never has to supply a password.
To set a hard password in AFC Manager:
1 Open the Site Configuration Dialog box
2 Click in the Site Options field. This action opens the Site Options dialog box
3 Select (check) option 4, Hard Passwords
When this option is selected, any authorization granted using Hard Passwords
times out after two minutes of inactivity, and the user will be required to re-enter
the password to continue.
