FAQs
Q1: What is the primary function of the PM858K02?
It is a redundant processor unit kit for the AC 800M controller platform. It executes control logic, manages data processing, and coordinates communication with I/O modules in System 800xA. The redundant configuration ensures uninterrupted operation in critical processes with switchover times of ≤10 ms.
Q2: What is included in the PM858K02 kit?
The kit includes 2 x PM858 CPU units, 2 x TP830 baseplates, 2 x TB807 ModuleBus terminators, 1 x TK850 CEX-Bus expansion cable, 1 x TK851 RCU-Link cable, and 2 x memory backup batteries (4943013-6).
Q3: Does the PM858K02 require a license?
No. The kit is supplied without a license included. A separate license is required for the control software (Control Builder M or 800xA Control Builder).
Q4: What is the difference between PM858K02 and PM858K01?
The PM858K02 is a redundant kit containing two CPU units for hot-standby configuration. The PM858K01 is a single CPU kit for non-redundant applications. Both share the same 33 MHz processor and 16 MB RAM specifications.
Q5: What are the typical applications for this controller?
The PM858K02 is used in medium-scale process control applications such as petrochemical reforming units, power plant auxiliary control networks, and metallurgical rolling lines where high availability is required but SIL3 certification is not mandatory. It is positioned between the PM857K02 (with SIL3) and PM860 in the AC 800M family.
