The latest entry into our Digitalization Digest consists of a project for a Pennsylvania Borough of an existing Grit Well control system that was based on a DCS system. The system was proving to be very costly and now effectively obsolete and could not be readily expanded. The system’s age made replacement of parts difficult, with long lead times and limited sources for the required parts.
For the new system, it was decided that the remote DCS I/O would best be a new Modicon hardware, to include a new PLC and panel to replace the existing remote panel. Modicon provided compatibility with the WWTP – supplier Activar VFDs as well as accessibility for product spares and replacements. The software selected for the control system was Ignition, an affordable product providing unlimited clients, unlimited data points, unlimited screens and remote alarming via email/SMS. A further advantage to the Ignition platform is that scalability is very cost-effective relative to the leading competitors. Additionally, the Ignition software was selected by PDA for the SCADA aspect as well as for the overall visualization of the project.
The new system is a standalone control system operated via Ignition. For estimation purposes, data collection was assumed to occur on up to 25 points and initially, the data points were collected and stored within the existing SQL database for the DCS system. As the changeover progressed the existing database became the Ignition database and provided historical long-term storage for both data sets. This action was predicated upon PDA having full access to the SQL database.
PDA provided the labor for engineering and data services, as well as for the system I/O requirements. PDA also provided hardware, including the main control panel that housed the controller, all M340 rack-based I/Os and an M340 rack for future expansion. This panel was also fitted with a door-mounted HMI touch screen for local control of the system. All control equipment was pre-installed in the cabinet, together with E-stop equipment, power requirements, and miscellaneous panel components.
At the completion of the project an internal assessment led to the following observations:

Network Review and Upgrade for a Chemical Company
The first entry in our Digitalization Digest (articles and thoughts regarding manufacturing plant digitalization) consists of an Ethernet modernization planning project for a chemical company located in the southeastern USA. The company has seven distinct site locations on a campus that employs hundreds of people. The project was to gather information on all switches, media connections, and equipment related to the network for the purpose of executing a methodical, phased upgrade.
The review process included assessments of over 150 managed and unmanaged switches, the main distribution frame (MDF), all intermediate distribution frames (IDF), as well as the connections from industrial switches at the site to each other and to computers/databases/terminals. The project was specifically targeted at Level 1 and higher on the ISA-95 model, not focusing on PLC connections to the production processing equipment level.
The company had a moderately accurate inventory of their managed switches and main computers (essentially everything with an IP address). The network is monitored by two different pieces of management/monitoring software (MNS), these being IntraVUE and WhatsUp Gold. However unmanaged switches, fiber media converters, and patch panels had not been inventoried effectively and devices like these had been added throughout the campus over the years. Added challenges were that much of the hardware was fifteen years old or older and had been installed in an open-air plant environment so that the exteriors of the machines etc. were in poor condition.
Post onsite investigation, a plan was generated to consolidate equipment – multiple smaller switches were to be replaced by larger switches. Reuse of the patch panels was originally considered, but after discussions with the client, it was evident that newer update patches would be preferred in most cases. Every effort was made to create the lowest quantity of unique situations, i.e., minimizing variability and design time, and to reuse existing punch-downs if serviceable and able to be transferred into new enclosures.
A proposal was completed for migration of each site and included the following:
PDA developed plans to move forward and provided documentation for each of the seven sites that identified all components of the network, with photographs and labels. The project is ongoing, and every effort will be made to provide easier access to the network as well as the ability to identify problems when they arise. Further upgrades to any of the seven sites will be more readily achieved as they become necessary.

Manufacturers throughout the United States are beginning to enjoy fully integrated systems. This doesn’t just mean integrated equipment lines, rather, it includes real-time ERP connectivity, connectivity to labeling software and systems, connectivity to physical warehouse via AGV interface and control, and connectivity to the finished goods storage. As plants need to deal with increased capacity requirements or added products, flexible packaging cells, multi-reel labelers, automatically-delivered materials for all portions of packaging, and flying line changeovers, integrated systems can help plants deliver on these requirements.
Generally, these manufacturing systems can be added, or capacity increased via the aforementioned equipment. However, today’s plants are running increasingly fast and complex packaging solutions that are not as easy to duplicate or extend. Thus, every second of uptime counts when getting the most from packaging assets. A system that is properly tuned to operate as an integrated system is one that provides immediate, relevant information and connects the machines, the personnel, and the maintenance software operations. For example, a line which can alert operators to pending or existing maintenance requirements, while simultaneously requisitioning the required parts and re-ordering those same supplies, is easier for the plant staff to operate holistically. The largest pitfall remains legacy equipment that cannot participate in the connectivity the way adjacent equipment or lines are able. Ultimately, the systems affect personnel and integrated systems help to have personnel more connected with the entire operation, and the true power of integrated systems is realized!
