3. Implementation of the communication option cards
Standard HTTP server
The storage capacity of the VW3 A3 310 Ethernet card for Web server files has been increased: 1.536 kb, as against 196 kb for the VW3 A58310 Ethernet card.
The maximum number of URL files has changed from 50 to 150.
Transferring all the URL files present on the Altivar 38’s Web server to the Altivar 61’s Web server is not permitted. There are several reasons for this:
•The drive parameter addresses are totally different between the two drives and these addresses are displayed in the Web pages by means of a file that can be found on the drive Web server: "DataFile.txt".
Apart from that, the content of the Web pages remains identical, and the Applets support the developments on the VW3 A3 310 card (example: the "Altivar Viewer"/"Altivar" page has been updated to support the Altivar 61’s additional inputs, outputs and relays).
Nonetheless, if you have added functions to the Altivar 38’s standard HTTP server and you wish to apply them to the Altivar 61’s HTTP server, it is your responsibility to adapt them in accordance with the Altivar 61 Web page format, before transferring them to the Altivar 61’s Web server.
"PDA Altivar" page: Last Fault = ILF Fault
This page is no longer used with the Altivar 61’s VW3 A3 310 Ethernet card.
Communication fault
Ethernet communication faults are indicated by the red RD LED on the card.
Parameter [Network fault]
Value | Description of the values of the [Network fault] |
0No fault
Tcp/Modbus Time out fault.
The Tcp/Modbus Time out is activated as soon as the control word is received:
1• If no IP master has been configured, the period of activity is maintained by receipt of the control word.
•If an IP master has been configured, the period of activity is maintained by any type of Tcp/Modbus request on this IP address.
No Time out is managed if its value equals 0
10Ethernet network overload
11No signal from the Ethernet network, cable pulled out, etc.
FDR service fault (EPF2)
The EPF2 communication fault is indicated by the red RD LED on the card.
This fault appears when a problem arises during the FDR status diagram sequence on the drive, provided that the FDR service is being used and that FDR errors are permitted on the drive ([FDR Error Mgt.] (FdrG) = [Yes] (YES) or FDR file error (address 60 060) = [No] (nO)). This fault is resettable.
The EPF2 fault is also triggered if the drive IP address is already being used by another device. In this case, the EPF2 fault is not resettable. You should then modify the drive IP address, or that of the device using this IP address, then restart the drive.
It is possible to obtain more detailed information about the origin of the fault. It can only be accessed on the graphic display terminal, in the [1.9 COMMUNICATION]
Value | Description of the values of the [Network fault] |
2FDR configuration file incompatible
3Error reading the FDR file
4Error writing the FDR file
7Time out for receipt of the FDR file has elapsed. This time out can be set by the network configuration software.
9Duplication of the IP address
12 | FDR file not present in the FTP server |
