AC 800M HI controller for the CRF
I was wonder if somebody can approve safety compatibility of AC 800M HI controller (PM 865 CPU + AI/AO/DI/DO880) for the Claus reaction furnace. At the present day we have HIMatrix SIL-3 compatible controller installed on reaction furnace. This controller connected to the 800xA automation system via Modbus. List of controllable parameters is fixed but customer wants to control more parameters. We are not able to modify HIMatrix code because we don't have program sources.
So we decided to replace HIMA and I'm looking for a suitable PLC.
AC 800M HI would be a good choice because our automation system consist on AC 800M controllers. Can AC 800M HI control the Claus reaction furnace? Or I need to look for the ABB Pluto PLC or PILZ? Anybody have an experience of usage AC 800M HI for such tasks?
Thanks for the futher replies

If you are concerned whether HI controller is suitable for furnace control or not, then please note that EN50156 is the safety standard for furnace control and HI controller is certified as per this standrad (you may refer TUV certificate).
In case, you have any other specific concern, please let us know so that we can look at it.
