ABB FREEL ANCE DISTRIBUTED CONTROL SYSTEM — System architecture Overview — Freelance Distributed control system for Process In A Freelance system can consist of one or combination of several AC 700F, AC 800F and/or AC 900F controllers. It can be connected to field devices through fieldbuses, direct and remote I/Os. With the AC 800F and AC 900F controllers, you have the option of configuring your entire system in redundancy. As shown in the architecture drawing below, Freelance can go from a typical OEM offering with an AC 700F controller, a Panel 800 and around 50-100 I/Os. The AC 700F can...

DISTRIBUTED CONTROL SYSTEM ABB FREEL ANCE Freelance can go up to thousands of I/Os. Connections include FOUNDATION Fieldbus, PROFIBUS and HART as well. There is also the possibility to connect to supervisory control stations running on ABB’s 800xA system. Freelance comes with three different types of controllers, AC 700F, AC 800F and its latest Freelance controller – the AC 900F. This controller truly extends the hardware portfolio of Freelance distributed control system. All three controller types can be used side by side within a project and can easily communicate with each other via the...

ABB FREELANCE DISTRIBUTED CONTROL SYSTEM System communication The operator and the process level communicate via the control network, which is based on Standard Ethernet. You can choose between various transmission media such as twisted pair or fiber optic cable. The system components use a specific protocol called DMS, which is an enhanced MMS (Machine Message Specification) protocol. This protocol can be utilized by 3rd party network subscribers using the application interface DMS-API. This is a “C” programming interface for MS Windows to enable programmers to create tailored solutions. A...

DISTRIBUTED CONTROL SYSTEM ABB FREEL ANCE — The controllers AC 900F, AC 800F and AC 700F The process level is the domain of controllers. Together with the engineering tool, their functions and modularity define the ease of use, scalability and performance of a DCS. Freelance comes with three different types of controllers: AC 900F, AC 800F and AC 700F. A Freelance system can consist of one or combination of several AC 900F, AC 800F and/or AC 700F controllers. It can be extended with fieldbuses, field devices and remote I/Os. With AC 900F and AC 800F you have the option of configuring your...

ABB FREELANCE DISTRIBUTED CONTROL SYSTEM The AC 900F controller truly extends the hardware portfolio of Freelance distributed control system. Apart from its highly sophisticated automation functions, the AC 900F modular controller offers expanded flexibility via a pluggable SD card, more Ethernet ports, redundancy options for high availability and powers for around 1,500 I/Os when using the Plus and Standard CPU (PM 904F and PM 902F) or up to 400 I/Os when using the Lite CPU (PM 901F). Key features of the AC 900F are increased performance, on-board interfaces and the support of SD cards....

DISTRIBUTED CONTROL SYSTEM ABB FREEL ANCE PROFIBUS modules for PM 902F and PM 901F. The PM904F can handle up to four PROFIBUS modules. You have the option to run these controllers in redundancy.
