1.8 APKieffer-TWTA-AC

This page describes the device driver and the device window for a customized TWTA air condition controller from AP Kieffer/Siemens.

The driver uses the Modbus TCP protocol. The default TCP port used is 502.

Device window pages

The following table shows which device window pages are available with this individual device type. Tool-bar functions not mentioned here are described at the general description of device windows .

Configuration parameters

At the maintenance page of the device window there are a couple of configuration parameters which must be set to make the software talk to the device.

parameter description
address Must always be set to 1 if the device is controlled Modbus over a serial line. With Modbus/TCP the device address doesn't matter.
