A small number of distributed third-party devices can be connected quickly and economically at the field level and further processed in the automation system. The devices are integrated either via digital/analog inputs and outputs, or via microprocessor-based interface modules.
The microprocessor-based DESIGO™ TX OPEN modules connect selected third-party devices via RS232 or RS485 to the distributed input/output field bus of the automation station. The TX OPEN module maps the third-party data points on the module bus to a number of virtual standard modules.
Examples of vendor-specific protocols:
