Connection mode TCP/IP

This mode activates a connection via the standard network interface of the computer.

Connection mode

Selection of the TCP/IP connection mode

Connection type

Selection of the connection type PG, OP, or other connections (determines which type of connection resource is occupied on the CPU).

Timeout

Specify a value for the timeout in seconds for establishing the connection and for read access. If the time set here is exceeded, ibaPDA declares the controller as not accessible or not responsive.

Address

IP address of the controller

Port

Number of destination port on the controller

Note

For the communication with the CPU, the port that is specified here must be allowed in the target system. If data traffic passes through an external firewall, you must also allow the specified port in this firewall.

Rack

Rack number of the controller (default: 0)

Slot

Slot number of the controller in the rack (Use "0" for S7-1500 CPUs.)

<Test>

ibaPDA tests the connection to the CPU and displays available diagnostic data.

Local port

By default, Windows assigns the local TCP port for S7 connections dynamically. Here, you can specify a static port if required.

Activate S7 routing

Activate this option if the S7-CPU and the ibaPDA computer are not in the same network, but only communicate over a gateway that supports S7 routing. Such a gateway can be e.g. an IE/PB link, over which a S7-CPU can be reached without an Ethernet connection.

Two additional input fields appear:

Address of device acting as gateway: Enter the IP address of the gateway.
S7 subnet ID of target net: Enter subnet ID from STEP 7 NetPro or TIA Portal.

For more information on S7 routing, see S7 routing.

CPU Name

Selection of the linked address book

Tip

If you do not know the rack number and/or slot number, enter "0" and click the <Test> button.

ibaPDA then tries to establish a connection. If the connection is successfully established, ibaPDA scans the relevant rack for available CPUs. ibaPDA lists the CPUs found with rack number and slot numbers. The CP to which ibaPDA is directly connected is always at the top.

When you click on an S7-CPU (hyperlink), ibaPDA establishes the connection and displays the CPU diagnostic data.

Note

For the communication with the CPU, port 102 must be allowed in the target system. If the data traffic runs via an external firewall, then you must also allow port 102 through this firewall.
