Remote Controlled
The analog outputs on the XTDL-HT™ can be remotely controlled via its Modbus interfaces. In addition
to configuring the channels remotely, the instrument allows the Modbus master to directly control its
analog outputs. This allows the DCS system to control another device via the XTDL-HT™ without setting
up a Remote Terminal Unit.
