Virtual VMS, RSView,iFix, Emerson DeltaV Connect Edit project Chemical Loop Team / MPC Project for Recovery/Recaust Project nameChemical Loop Team / MPC Project for Recovery/Recaust Apr 2009 – Sep 2010 Project description MPC Control with goal of 85% Caustivity and $1,771,238 savings in steam use and chemical make-up as NaOH. Primary DCS Engineer for PC setup, OPC setup and tag configuration, PI Data historian tags and configuration, MPC to DCS Communications, Regulatory Controls in DCS, Instrument installation, Loop Tuning, Script design for proper line up of controls prior to switch to MPC Control, Watch-dog timer design and configuration for swap back to DCS Regulatory Control on communication failure. A total of 11 MPC Controllers across two lines was implemented. Edit project Power House Mill Water Usage Project Project namePower House Mill Water Usage Project Sep 2010 – Sep 2010 Project description Moved Rack of I/O from one PLC to another PLC. This was to adjust for a implementation style of putting I/O on the nearest PLC to a style of locating I/O via functional area. This allows for maintenance outage of an area with reduced risk to other areas when PLC programming changes are requested. Edit project PM1 Line Shaft Steam Turbine Control Project namePM1 Line Shaft Steam Turbine Control May 2009 – May 2009 Project description A) Kepware OPC Server for PM1Peak MicroLogix 1100 to monitor PM1 Line Shaft Woodward Governor via MODBUS. B) Developed MODBUS Simulator using MicroLogix for testing in Engineering Lab. Edit project Prep work for Recovery/Recaust MPC Project Project namePrep work for Recovery/Recaust MPC Project Mar 2009 – Mar 2009 Project description A) Install RoviSys OPC90 for Bailey connectivity for Recaust and Kiln Advanced Controls B) Programmed ProSoft MODBUS card in Allen Bradley PLC5 to interface to NIR Duralyzer Edit project 4-20ma Speed Setpoint for ID Fan Project name4-20ma Speed Setpoint for ID Fan Feb 2009 – Feb 2009 Project description Decision made to put a hard analog set point for speed control of ID Fan instead of dependance on MODBUS Communications. Installed 1771-NOC analog card in PLC5, configured and interfaced to Bailey PID via DF1 Interface. Edit project TG1 & TG2 Mark III+ Interface Replacement Requirements Project nameTG1 & TG2 Mark III+ Interface Replacement Requirements Aug 2008 – Aug 2008 Project description Determine requirements to replace interface from Bailey to Mark III+ Turbine Controllers from MFC03 Controller. Everyone impression was that it was a MODBUS interface and the thought was to move it to PLC5 with ProSoft MODBUS Card. Turns out it is a custom protocol interface and we didn't have source code. Decision made to wait for Turbine Controls upgrade Edit project Steam Trim Controller Project nameSteam Trim Controller Jun 2008 – Jun 2008 Project description When Recovery Boiler is being fed black liquor by mass flow(KPPH) instead of liquor flow(GPM) the boiler can exceed its rated steaming capability. The Steam Trim Controller was added to adjust the Flow Controller's setpoint by a factor of +/- 10% when the mass steam flow is > 600 KPPH to prevent over steaming the boiler past its rating. Edit project In House Recaust Area Training Project nameIn House Recaust Area Training Apr 2008 – Apr 2008 Project description A) Recausticizing Training Video B) Green Liquor Training Video C) White Liquor and Mud Training Video D) Lime Mud Filter Training Video C) Lime Kiln Mechanical Training Video Edit project In House Bailey Lab Training Project nameIn House Bailey Lab Training Mar 2008 – Mar 2008 Project description A) Model Level Loop and Flow Loop B) Tuning Level Loop and Flow Loop C) Modeled Stop and Start Motor Logic In Bailey and PLC5 Edit project Precipitator Rapper Panel Upgrade Project namePrecipitator Rapper Panel Upgrade Jan 2008 – Jan 2008 Project description Vendor installed new controls for rappers. Developed PLC5 logic to interface via MODBUS to vendors CAN Transceiver to receive data and provide control to vendors controller via MODBUS to CAN protocol. Interfaced PLC5 to Bailey Infi 90 via DF1 protocol interface so that operators could control rappers from Bailey and receive alarms from rapper controller panel. Edit project Chip Quality Project nameChip Quality Project description Designed and implemented a Client/Server System that captured Chip Quality Data from Chip Grading machines. The system automatically sends e-mail reports to Suppliers, allowing them to make adjustments to their equipment, to meet required specifications. Application featured in Corporate Newsletter and allowed a two and a half million dollar savings, the first year it was implemented, for the Division. Edit project Estimated Production Report Project nameEstimated Production Report Project description This application was developed in the late 90's and is still in production today. It is basically a application to record all aspects of a shift's production, i.e. grade changes, speed changes, defects, etc... Developed with PowerBuilder Client/Server toolset with an Oracle database backend. Data has been queried multiple times through the years to support Improvement Teams. Edit project Flow Charted Bailey BATCH90 programs for Soot Blowers Project nameFlow Charted Bailey BATCH90 programs for Soot Blowers Project description Operations wanted to change Soot Blowers from Pressure control to Flow Control. Very in depth and old BATCH90 code was developed in-house to control Soot Blower Sequence for 53 Soot Blowers. Flow charted in preparation for this request. Decision made to not implement. Edit project Storeroom Handheld Barcode Scanner Project nameStoreroom Handheld Barcode Scanner Project description Late 90's application to allow storeroom personnel to download data from SAP of storeroom inventory and allow issuing of items with a handheld scanner by scanning employee clock number, items issued by a barcode. Developed with Borland Delphi, Oracle database backend, Flow charting programming software for scanner. Recently replaced with scanner that talks directly to SAP. Storeroom tell me they wish they had this application back.
