8000 Series I/O

An 8000 Series node comprises single or redundant Ethernet Bus Inter-face Modules, up to 64 I/O modules, field terminals, and associated power supplies.

A schematic node architecture is shown below. In- formation from the I/O modules is transferred to and from the communication module (EBIM) via the Rail- bus. The Railbus is a fast, serial data bus with parallel module addressing and extends over the full length of the node. The parallel address architecture means that each I/O module position has a unique address which eliminates the need to ‘train’ modules during installa- tion.

Power for the node is provided by integrated power supply modules; these convert the locally available power source into a regulated internal supply rail. This rail energizes the EBIM and all Railbus communication between the EBIM and I/O modules.

For some I/O module types—such as those with low-power and intrinsically safe field circuits—it also provides power for the field wiring. Where additional power is required for field devices (such as high cur- rent AC circuits), power can be provided by means of cabled connections from each module to external relays. This Bussed Field Power facility reduces instal-

lation time by removing the need to make daisy chain wiring connections at the field terminals of each I/O module.

Node Operation

A typical request for data from the field might happen as follows:

The D/3® PAS requires the temperature from a par- ticular thermocouple input at a particular node and transmits a signal on the I/O LAN. There are several Series 8000 nodes on the I/O LAN, but the EBIM at the chosen node recognizes its own node address, and acknowledges the request.

At each node, the input modules constantly monitor, linearize and digitize their respective field signals, and make them available to scanning on the node’s internal bus (Railbus).

The EBIM continually scans the I/O modules via the Railbus, and builds up a map of the values of the input variables, ready for the PCM to read. These are con- verted into the LAN protocol and placed on the LAN by the EBIM, together with acknowledgement signals. The D/3 then interprets the signal and reconstructs the temperature reading.
