Connection mode TCP/IP S7-1x00

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.

Local port

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

Password

Depending on the configuration in the controller, access to the PLC may be protected by a password. In this case, enter this password here.

Use secure communication

The S7-1500 controller supports secure communication via TLS encryption with TIA Portal v17 or higher. In TIA Portal, you can set secure PG/PC and HMI communication. If you have activated this option in the controller, you must also activate secure communication in ibaPDA.

DB

Number of the data block used as ibaPDA communication interface (ibaREQ_DB)

PROFINET Device Slot or PROFIBUS slave number (not for ibaNet-E)

• PROFINET: Number of the used slot of the ibaBM-PN

• PROFIBUS: PROFIBUS slave address assigned to the module. If you change the entry in the Connection tab, the entry in the General tab changes accordingly and vice versa.

CPU Name

Selection of the linked address book (only TIA Portal address books available).

Detect S7 restart

The current request configuration is stored in a data block on the CPU. In case the Detect S7 restart option is enabled, ibaPDA can detect if this data block has been deleted or overwritten, e.g. as a result of loading the offline program or due to a cold restart, and restarts the data acquisition. The configuration data are transferred again. This does not affect a warm restart of the CPU.

<Test>

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

<Load address book from S7>

By clicking on this button ibaPDA reads the list of symbols directly from the PLC and stores it in an address book for further use in the symbol browser.
