Abstract
A field transmitter F, a control device B is in the form of a separately portable unit linked to a field transmitter S1 by radio over short ranges. This eliminates the need to make a direct visit to an inaccessible field transmitter S1 for control purposes. In addition, one control device B can be used to control a plurality of field transmitters S1, S2, S3, A1, A2 by radio. In situ control, which is normally permanently integrated into the field transmitters S1, S2, S3, A1, A2, can be dispensed with.
Claims9
A method for controlling a field transmitter S1 for process automation having in combination therewith a control device B for input and display, comprising at least one of the following steps:
- transmitting software changes (up dates/up grades) to the field transmitter S1 using the control device B;
- initiating a recurrent test on the field transmitter S1 using the control device B;
- making a status query for the purpose of predictive maintenance of the field transmitters S1 using the control device B;
- and
- executing said steps of transmitting, initiating and making by a radio link on the basis of the Bluetooth standard between the field transmitter S1 and the control device B.
