To configure a module, select it in the tree structure.

All modules have the following setting options.
Basic settings

Module Type (information only)

Indicates the type of the current module.

Locked

You can lock a module to avoid unintentional or unauthorized changing of the module settings.

Enabled

Enable the module to record signals.

Name

You can enter a name for the module here.

Comment

You can enter a comment or description of the module here. This will be displayed as a tooltip in the signal tree.

Module No.

This internal reference number of the module determines the order of the modules in the signal tree of ibaPDA client and ibaAnalyzer.

Timebase

All signals of the module are sampled on this timebase.

Use module name as prefix

This option puts the module name in front of the signal names.

Text encoding

You can select the type of text encoding or the code page here for a correct interpretation and display of the received text data for inputs as well as of the text data to be sent for outputs. Available for selection are, beside system locale according to the Windows system settings (default) and UTF-8 Unicode, all other encodings.
Module Layout

No. analog signals/No. digital signals

Define the number of configurable analog and digital signals in the signal tables. The default value is 32 for each. The maximum value is 1000. The signal tables are adjusted accordingly.
S7

CPU name (not available with all modules)

Address book to which this module is connected. This is where the symbolic operands are selected.

Update time

Specifies the reference update time in which the data is requested from the PLC. During measurement, the real current update time may be higher than the specified value if the PLC needs more time to transmit the data. You can check in the connection table how fast the data is actually updated.

Access mode

The amount of data that an S7 can read in a single message is limited. Therefore, for larger amounts of data, several messages are used which can be controlled via the following send behavior:

  • Parallel mode: Messages are sent directly in succession without waiting for a response from the S7 (fast mode, but not supported by some PLCs or adapters).

  • Sequential mode: Messages are only sent consecutively after the S7 has responded to the first message.

Connection (read only)

Connection ID that is used to access S7.
"Select symbols" link

Click on this link after the connection has been successfully established to configure the signals to be measured.
