  PM891 Processor Unit – General  

PM891 is a high performance controller, which is capable of handling applications with
high requirements.

PM891 connects to the S800 I/O system through the optical Modulebus. It can act as a
stand-alone Process Controller, or as a controller performing local control tasks in a control 

network.

Two PM891 controllers can function together as a redundant pair, with one PM891 acting
as the primary controller and the other acting as the backup. The backup controller takes
over the process controller tasks if any hardware error occurs in the primary controller.

The control network connectivity is obtained by two built in IEEE802.3 Ethernet channels
on PM891.

PM891 also provides a communication expansion bus (CEX-Bus) to which a number of
expansion modules can be connected. These modules offers connectivity to a wide
range of field bus and I/O systems. In case of a redundant pair, both PM891s are
connected to the same CEX-Bus and one of them can control the modules.

Physically, the PM891 Processor Unit consists of:
• Connector for power supply and status signals (L+, L-, SA, SB).
• DB25 connector for Electrical CEX-Bus.
• External battery connector.
• RJ45 connectors for the two Ethernet channels.
• One Communication port.
• Optical Modulebus connector for connection to a maximum of seven clusters, with
12 non-redundant or six redundant modules (that is, 7x12 = 84 modules).
• Connectors for Redundancy Link.
• SD (Secure Digital) memory connector.
• LEDs.
• Pushbutton reset switch.
