Description:
The CI851 and TP851 assemblies, shown in Figure 25 on page 73, are used for connecting remote I/O and fieldbus instruments via PROFIBUS DP. The TP851 base plate has one female DB9 connector for connecting PROFIBUS DP. The base plate has a preset, two letter Alpha code lock to prevent the installation of an incorrect type of unit onto the TP851 base plate.

The CI851 is powered by the processor unit, via the CEX-Bus, and therefore does not require any additional external power source.
The PROFIBUS DP must be terminated at the two outermost nodes. ABB recommend the use of connectors with built-in termination, since the fieldbus will then always be terminated, even if it is disconnected from the unit.
It is also possible to connect PROFIBUS PA to the CI851 via the PROFIBUS linking device LD 800P, see Appendix B, Recommended Components.
It is not possible to change the CI851 via Hot swap and it is not allowed to perform an online upgrade of firmware in a system containing CI851.
CI851 cannot be used in a High Integrity controller.
CI851 has been replaced by the CI854 communication interface. CI851 is only described for legacy reasons.
