Text signals can be received via different PLC or manufacturer-specific interfaces, where they are typically processed as analog signals with the STRING[x] data type.
The text interface also offers the possibility to receive text information in other ways. For this purpose, the following modules are available via this interface:
|
Module type |
Function |
|---|---|
|
TCP text |
ibaPDA receives the text as a TCP/IP telegram via the network interface. |
|
UDP text |
ibaPDA receives the text as a UDP datagram via the network interface. |
|
Serial text |
ibaPDA receives the text via a serial interface (COM1…COM4). Converters are supported, e.g., from RS232/RS485 to USB. |
|
File text |
The text is available in a text file (*.txt, *.csv, *.json), which is opened and read by ibaPDA. |
All these module types can be adapted to the source text in order to read out the desired information and convert it into text signals.
Detailed information about the handling of text signals as well as the descriptions of the interface and modules can be found in Text signals and text processing.
