CI860 ABB Ability™ System 800xA® hardware selector

If there is a need to have access to FF process variables in the AC

800M controler, connectivity between the HSE subnet and the

contro ler is established with the CI860 - the Communication

Interface FOUNDATION Fieldbus HSE.

Then FOUNDATION Fieldbus process data on HSE can be accessed

from the IEC 61131 applications in the AC 800M controlers. For this

purpose, the CI860 module maps the value and status parts of the FF

signals to the IEC 61131 application and vice versa.

The CI860 is powered by the processor unit, via the CEX-Bus, and

therefore does not require any additional external power source.

Features and benefits

• The CI860 can be used in redundant mode

• Up to twelve CI860 modules can be placed at one AC800 M also in redundant mode, and each of them

can be connected to the same or to a separate FOUNDATION Fieldbus HSE subnet.

• The ABB FOUNDATION Fieldbus Linking Device LD800HSE/LD 800HSE EX acts as a gateway between

the HSE subnet and up to four separate H1 links.
