A first unit ( 200, 303, 304 ) works with analog and digital signals in physical sequences referring to one or several measurement objects ( 200', 305, 307 ), which work with one or several functions ( 200'', 211, 302, 308, 309 ) and detectors ( 201, 202, 205 ) and/or control devices ( 212/214 ) detecting these functions. A distributed control system ( 206 ) works with a first protocol ( 218 ). The first unit ( 200 ) is connected to the control system ( 206 ) and is arranged, through its compatibility with the first protocol ( 218 ), to receive and/or send messages from/to the control system. The first unit ( 200 ) receives and sends physical signals for measurement and/or control of various types and combinations of functions and/or detectors or control devices, and processes the physical signals. The first unit is connected to a second connection ( 209 ) working with a second protocol ( 418 ). The second connection is in a link in a tool arrangement. The first unit communicates with a second unit ( 450 and/or 201, 221 ) via the second connection ( 209 ). The first unit can be set up via a connection that works with the first and/or the second protocol(s) or variant(s) thereof. In this way, more complex and simpler tasks can be dealt with separately, and can be divided up between different pieces of equipment and different people. |
