Arrangement for distributed control system
First Claim
1. An arrangement for at least one of analyzing, simulating and monitoring functions and/or structures in a distributed control system (24) that works with a first protocol (29), comprising:
- at least one first unit (23, 26) connected to the distributed control system via contacts (5′
, 6′
, 6″
), the at least one first unit, by means of the first protocol, receives and/or sends task instructions concerning the monitoring functions and/or structures; and
a second unit (22) connected the first unit and to a tool arrangement interactable with a user and further comprising;
a first computer (21) able to carry out calculation, simulation and/or analysis tasks, ora second computer connected to the first computer that is adapted to configure the second computer, wherein the second computer is adapted to carry out at least some of the tasks of the first computer,wherein the at least one first unit transforms, at least those parts in the first protocol (29) that relate to said tasks into a second protocol (28), by means of which the tasks or parts of tasks can be carried out by the second unit (22),wherein the second unit, by means of the second protocol (28) or a third protocol (27), can communicate with the tool arrangement, which by readings and/or modifications in the first protocol and in the first and second protocols, respectively, can carry out the readings and/or modifications in a same way in the second and third protocols, respectively,wherein the at least one first unit (23, 26) further comprises at least one microprocessor which communicates partly with the distributed control system by means of a connection, a protocol and a bit speed valid for the distributed control system, and communicates with the second unit (22),wherein the second unit is equipped with at least one microprocessor adapted to communicate and exchange information with the at least one first unit and the tool arrangement, andwherein primary readings and/or modifications in the first protocol on the basis of the analysis and/or monitoring can be carried out by means of secondary readings and/or modifications in the second protocol.

Abstract
In an arrangement, functions and/or structures in a distributed control system (24) that works with a first protocol (28) are analysed and/or monitored. A first unit (23) is connected or can be connected to the control system, which first unit, due to its compatibility with the first protocol, receives and/or sends task instructions concerning the functions and/or structures. The first unit comprises or is connected to a second (22) and transforms at least those parts in the first protocol that relate to the task instructions concerning the functions and/or structures into a second protocol, by means of which the said tasks can be initiated and/or carried out in a tool arrangement (1) that is comprised in or can be connected to the second unit. This tool arrangement works with the second protocol, whereby primary readings and/or modifications in the first protocol on the basis of the analysis and/or monitoring can be carried out by means of secondary readings and/or modifications in the second protocol. The analysis and monitoring are simplified and tools and protocol-handling can be separated. In addition, time functions in the system(s) can be made unambiguous.
