Description

This interface provides ibaPDA with access to a SIMATIC S7 PLC via TCP/IP or UDP. The connection should be established over CP 443-1 for S7-400 CPUs or CP 343-1 for S7-300 CPUs.

The data to be measured will be moved by the S7 application program into data blocks (DBs) and stored in a fixed data structure. This structure is derived from the ibaPDA module types. The DBs are then sent as a message to the ibaPDA computer via S7 communication blocks (FCs). A specific connection must be configured on the S7-CPU for each message.

The maximum length of the message is limited to 4096 bytes.

Up to 64 connections can be used per interface license. By purchasing up to 3 one-step-up licenses, the number of connections can be increased up to 256.
Interface configuration

Port number

The port no. must be exactly the same as previously configured when setting up the S7 connection.

<Reset port to default>

Use this button to reset the port to the default port number.

Allow ports through firewall

When installing ibaPDA, the default port numbers of the used protocols are automatically entered in the firewall. If you change the port number or enable the interface subsequently, you have to enable this port in the firewall with this button.

Network interfaces

Using this drop-down list, you can select which network adapters on your computer are used for this interface. The sockets will be opened for communication only on the selected network adapters. In case a network adapter has multiple IP addresses configured, a socket will be opened for all of these IP addresses. At least one network adapter should be selected to get the interface configuration validated. If you select None, an error message will be displayed when validating the I/O configuration. By default, the option All is selected.

TCP/UDP port

"OK" is displayed here if the socket can be opened on this port. ERROR is displayed if conflicts occur, e.g., if the port is already busy.

<Reset statistics> button

By clicking on this button you can reset all the counters in the table.

Address

This is the IP address of the source computer from which ibaPDA receives data.

Mode

TCP or UDP communication mode display

Module index

The module index indicates which module number in ibaPDA should be assigned to this connection. The module index must be configured in the source system, e.g. ABB, ibaLogic. This module index must correspond to the entry in the field, Module index, in the corresponding module of the I/O Manager (module level, General tab). If necessary, adjust the module index on the source page or in ibaPDA.
