A portable field maintenance tool with a resistor network to the intrinsically safe operation

摘要

A portable field maintenance tool can carry out one or more tasks, such as, for example, communicate with a field device, a field device supplied with power, a field device diagnosing, or a communication link in a plant environment diagnosing, a field device is connected with the. The portable field maintenance tool can interact with field devices which, according to a number of different communications protocols are arranged, such as, for example, of the hard - protocol, and of the field bus - protocol. The portable field maintenance tool, energy can be limited and error-tolerant and can be in compliance with intrinsic safety standards in operation, the use of the portable field maintenance tool in dangerous regions enables.
