Program |
|
| |
Operation Overview | • This program reads 150 words of the PLC memory beginning at D00100 | ||
|
| by sending a FINS command (MEMORY AREA READ, command code | |
|
| 0101) from a UNIX workstation (WS) to the PLC on the Ethernet network. | |
|
| • If no response is received within two seconds of sending the FINS com- | |
|
| mand, the command will be resent. | |
Settings | • The Ethernet Unit IP address is 196.36.32.100, and the FINS node | ||
|
| address is 100. IP address conversion is set to automatic generation | |
|
| (dynamic). |
|
• The FINS UDP port number for the Ethernet Unit is 9600 (default).
• The workstation’s IP address is 196.36.32.50 and its FINS node address is 50.
• The FINS UDP port number for the workstation can be a
