In addition to the access control for the file system, there is also an access
control for the HTML pages of the communication board. The file containing
the access passwords is located under the directory 'user\pswd', and it is
named 'web_accs.cfg'. As in the previous case, each line of the
'web_accs.cfg' file represents an access account. In order to change the
user accounts for the HTML pages, create a text file with the same name
('web_accs.cfg') and insert in each line of this file a pair 'login:password' for
the users with access permission. After that, transfer this new file through
FTP to the communication board, exactly as in the previous case.
NOTE!
It is strongly recommended to change all passwords of the EtherNet/IP
communication board after the start-up of the device. The new passwords
will be effective only after powering down and up the CFW-09.
NOTE!
When the inverter returns from the off-line state the output values are reset.
There are two main parameters: P309 and P313:
P309 - defines the used standard Fieldbus (Profibus DP, DeviceNet or
EtherNet/IP) and the number of variables (I/O) exchanged with the master
(2, 4 or 6). The parameter P309 has the following options:
0 = Inactive, 4 = DeviceNet 2 I/O,
1 = Profibus DP 2 I/O, 5 = DeviceNet 4 I/O,
2 = Profibus DP 4 I/O, 6 = DeviceNet 6 I/O,
3 = Profibus DP 6 I/O, (for DeviceNet),
(for Profibus DP), 7 = EtherNet/IP 2 I/O,
P313 - defines the inverter behavior when the physical connection with the
master is interrupted and/or the Fieldbus board is inactive (E29/E30).
- The parameter P313 has the following options:
0 = Disables the inverter by using the Start/Stop controls via deceleration
ramp.
1 = Disables the inverter by using the General Enabling, stop by inertia.
2 = The inverter status is not changed.
3 = The inverter goes to Local mode.
4 = The inverter changes to Local mode keeping the commands and the
reference.
1 - Logical Status of the inverter,
2 - Motor speed,
For the option P309 = 1or 4 (2I/O) - read 1 and 2,
3 - Status of the Digital Inputs (P012),
4 - Parameter Status,
For the option P309 = 2 or 5 (4I/O) - it reads 1, 2, 3 and 4,
5 - Torque current (P009),
6 - Motor current (P003),
For the option P309 = 3 or 6 (6I/O) - it reads 1, 2, 3, 4, 5 and 6.
1. Logical Status (E.L.):
The word that defines the E.L. is formed by 16 bits, being 8 bits of high
order and 8 bits of low order. It has the following construction:
8 = EtherNet/IP 4 I/O,
9 = EtherNet/IP 6 I/O,
(for EtherNet/IP).
10 = DeviceNet Drive
