Module S7-Xplorer decoder

The module is suitable for acquiring large quantities of digital signals from a SIMATIC S7 controller.

ibaPDA supports the following controllers, connection modes and selection methods:

Controller	Connection mode and signal selection
	TCP/IP			PC/CP			TCP/IP S7-1x00
	ABS	SYM	CFC	ABS	SYM	CFC	ABS	SYM	CFC
S7-300	X	X	X	X	X	X	-	-	-
S7-400	X	X	X	X	X	X	-	-	-
S7-1200	X	-	-	-	-	-	-	X	-
S7-1500	X	-	-	-	-	-	-	X	-

Explanation: ABSolute address, SYMbolic, CFC connector

ibaPDA supports the following operand types:

Selection via	Analog
S7-300 S7-400	EB, AB, MB, PEB, DBB EW, AW, MW, PEW, DBW ED, AD, MD, PED, DBD T, Z
S7-1200 S7-1500	EB, AB, MB, DBB EW, AW, MW, DBW ED, AD, MD, DBD

Module layout

No. of decoders

Define the number of configurable decoders in the digital signal table. The default value is 32. The maximum value is 128. The signal tables are adjusted accordingly.

Connection configuration

Set the connection of the S7-Xplorer Decoder module in the same way as the connection for an S7-Xplorer module:

Connection mode TCP/IP Connection mode PC/CP Connection mode TCP/IP S7-1x00

Digital tab

The declaration of the digital signals is done on two levels. First define the source signals, which are broken down for the digital signals (bits).

You can open each source signal via the <+> button to display the list of associated digital signals. Then define the individual digital signals of the source signal.

The individual columns of the signal table have the following meanings:

Source signal

Decoder

Enter a name for the source signal.

S7 Operand/S7 Symbol

Enter the S7 operand to which the signal is assigned and, if applicable, the S7 symbol.

DataType

Enter the data type of the signal. The data type also determines the number of digital signals. ibaPDA automatically derives the possible data type from the S7 operand or S7 symbol.

Active

If you activate the source signal, it is acquired with all digital signals. You can deactivate individual digital signals.

Individual digital signals (bits)

Name

Enter a name for the individual digital signals.

Active

If you activate the signal, the signal is acquired and is also considered when checking the number of licensed signals.

Note

ibaPDA only takes the activated digital signals into account for the number of licensed signals, i.e. no additional signal for the source signal.
