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.
Advanced
Swap analog signals
Option to change the order byte evaluation. The swap mode to be selected depends on the swap mode of the signal source.
MELSEC
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.

It is recommended to check the diagnostic overview (connection table) for measured update rates as overload will result in lost samples. |
Read mode
The read mode defines how data is read from the PLC.
-
Batch read: Most generic way of reading data. Neighboring operands are grouped into a single request message; otherwise a single message per operand is used. This is the least performant method but supported by most PLC types.
-
Random read: Most suited for situations where a lot of non-neighboring operands are requested. Not supported by all PLC types.
-
Monitor: Most performant method. The requested operands are registered once and the data is requested periodically. Limited to 192 operands and can only be used in one module per PLC. Not supported by all PLC types.
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.
