Abstract

A valve driver system for driving a plurality of valves of a valve manifold. The system includes a plurality of valve drivers, wherein each valve driver is configured to drive a zone of one or more valves of the manifold; and, a power board that separately powers the respective valve drivers such that the valve drivers are powered separately with a separate power source that can individually power the valve driver. A multiple safety zone valve driver system for driving a plurality of valves of a valve manifold. The system includes a plurality of valve drivers; a first safe PM output; and a second safe PM output. The first and second safe PM outputs are configured such that in response to a first type of safety event the first PM output shuts off power to the first one or more valve drivers and the second PM output maintains power to the second one or more valve drivers. A zoning adapter for adapting logical addresses of valve drivers to physical addresses of valves of a valve manifold A conversion portion converts logical addresses to physical addresses of the valves in the different zones of the valve manifold with a spacing in one or more portions of the logical addresses.

First claim

What is claimed is:

1. A zoning adapter for adapting logical addresses of valve drivers to physical addresses of valves of a valve manifold, the zoning adapter comprising:
a first end configured to receive logical addresses of a plurality of valve drivers;
a second end for connection to physical addresses of valves in different zones of the valve manifold, wherein the number of physical addresses is less than the number of logical addresses; and
a conversion portion that converts the logical addresses to the physical addresses of the valves in the different zones of the valve manifold with a spacing in one or more portions of the logical addresses;
wherein the zoning adapter includes a card, board, ribbon cable and/or wiring harness configured to port traces from the plurality of valve drivers to traces of an interconnection board for the plurality of valves of the valve manifold.

2. The zoning adapter of claim 1 , wherein the valve drivers are separately powered.

3. The zoning adapter of claim 1 , wherein the conversion portion converts 32 logical addresses (0, 1, 2, . . . 31) to 16 physical addresses of eight (8) valves.

4. The zoning adapter of claim 3 , wherein the 32 logical addresses are the logical addresses of four (4) different valve drivers each having eight (8) logical addresses.

5. The zoning adapter of claim 3 , wherein the eight (8) valves are in four (4) different zones of the valve manifold, and wherein the conversion portion converts the 32 logical addresses with a spacing in four (4) portions (4, 5, 6, 7; 12, 13, 14, 15; 20, 21, 22, 23; 28, 29, 30, 31) of the logical addresses (0, 1, 2, . . . 31).

6. A method of adapting logical addresses of valve drivers to physical addresses of valves of a valve manifold, comprising:
providing a zoning adapter including a card, board, ribbon cable and/or wiring harness configured to port traces from a plurality of valve drivers to traces of an interconnection board for a plurality of valves of the valve manifold;
receiving, by the zoning adapter, logical addresses of the plurality of valve drivers;
arranging, by the zoning adapter, physical addresses of valves in different zones of the valve manifold, wherein the number of physical addresses is less than the number of logical addresses; and
converting, by the zoning adapter, the logical addresses to the physical addresses of the valves in the different zones of the valve manifold with a spacing in one or more portions of the logical addresses.

7. The method of claim 6 , wherein the converting includes converting 32 logical addresses (0, 1, 2, . . . 31) to 16 physical addresses of eight (8) valves.
