Communication Options with LabVIEW

With the LabVIEW Touch Panel Module, you have several options for

communication between the TPC-2012 STE and NI programmable

automation controllers (PACs) and third-party PLCs including:

• Shared variables over Ethernet

• Native LabVIEW TCP/IP, serial, SMTP, or UDP

• Modbus TCP/IP or Modbus ASCII over Ethernet or serial

With this wide range of communication options, you can select the best

method for your application. The LabVIEW shared variable offers the

easiest solution for communication over Ethernet and shortens

development time so you can build a quick and powerful user interface.

For more advanced programming requirements, use the native LabVIEW

TCP/IP or UDP VIs to develop more refined Ethernet-based communication

or add e-mailing capabilities with built-in LabVIEW SMTP e-mail VIs.

Connect to external serial devices using one of the four RS232 ports.

For connectivity to Modbus PLCs or RTU controllers, use the LabVIEW

Modbus Library to easily communicate between a touch panel computer

and a PLC through the industry-standard Modbus protocol over Ethernet

or serial.
