6 Creating Project Files—SEAbus Port Expander

6.2SEAbus Device Setup—Port 2

One or more Siemens devices may be connected to port 2. You must have a SEAbus Port Expander project

file open to configure port 2 using the instructions in this section.

Select Port 2 (SEAbus Devices) from the Edit menu, and the Port 2 configuration screen appears.

Configuration Information

The configuration selections with the exception of Response Time-Out are the same as those for port 1. Refer to Section 6.1 for instructions on configuring these fields.

Response Time-Out

The Response Time-Out tells the DTU how long to wait after transmitting a request to the PLC if no response has been received from the PLC. After this amount of time passes with no response being received, the DTU will assume that no response is coming and will retry the request. Enter the time in milliseconds.

6.3Passthrough Setup—Port 3

Select Port 3 (Passthrough) from the Edit menu, and the Port 3 Passthrough configuration screen appears. It is identical to the port 1 configuration screen, but configures the communications settings for the super- visory computer connected to port 3. The settings can be different than those for port 1, depending on the system. See Section 6.1 for directions for setting up the passthrough port.

After configuring port 3, select Save to save the port 3 configuration to the project file, and then select Ok or press Esc to exit the Port 3 Passthrough configuration screen.

Saving Port 2 Configuration Information

Once you have entered all the configuration informa- tion, select Save to save the configuration to the project file. Then select Ok or press the Esc key to close the configuration screen.

If you have changed the configuration and have not saved it to the project file, you will be prompted to either save or discard the changes.

Select Revert to return to the last previously saved configuration without saving any changes.
