ABB CI860 COMMUNICATIONS - AC 800M COMMUNICATION INTERFACES

If there is a need to have access to FF process variables in the AC 800M controller,

connectivity between the HSE subnet and the controller 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 controllers.

For this purpose, the  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.

Protection functions

The IED offers directional and non-directional overcurrent and thermal overload protection as

well as directional and non-directional earth-fault protection. 

Some standard configurations allow as an option admittance-based, harmonics-based or wattmetric-based earth-fault protection to be

used in addition to directional earth-fault protection. 

Further, the IED features sensitive earth-fault protection, phase discontinuity protection, transient/intermittent earth-fault protection, 

overvoltage and undervoltage protection, residual overvoltage protection, positive-sequence undervoltage 

and negativesequence overvoltage protection. 

The outstanding I/O capability in REC670 enables control of several bays with complete measurement with only one IED. 

For instance, one REC670 IED is capable of handling control of all apparatuses 

in one entire diameter in 1 ½ breaker arrangement including breaker failure protection for all breakers.
