FAQ
FAQ
Q1: What is the maximum number of S800 I/O units supported per PM891 processor?
A1: Each PM891 can connect up to 7 clusters of S800 I/O units, with a maximum of 12 units per cluster.
Q2: Can the PM891K02 processor perform hot replacement?
A2: Hot replacement requires the BC810K02 unit, which must be ordered separately.
Q3: Are the Ethernet ports on the PM891 redundant?
A3: Yes, the PM891 has built-in redundant Ethernet communication ports.
Q4: Does the PM891 contain an internal battery?
A4: No, the PM891 does not include any internal battery.
Q5: What type of CPU redundancy does the PM891 support?
A5: It supports CPU, CEX-Bus, communication interfaces, and S800 I/O redundancy for high availability.
Q6: What is the purpose of the COM4 serial port?
A6: The isolated COM4 port is used exclusively for configuration tools.
Q7: What is the protection class of the PM891?
A7: The PM891 has IP20 protection, eliminating the need for additional enclosures.
Q8: How does the CEX-Bus interconnection enhance system availability?
A8: Using the BC810 unit, the CEX-Bus can be divided into separate segments, reducing fault propagation and increasing overall system availability.
