Control System for an AgState Grain Terminal

Problem:  

AgState, Alton IA had plans for a major expansion, but they wanted to change control vendors. They needed to find a company that could:

• Support their current system
• Update and make changes to their current system
• Provide seamless programming for the major expansion  and integrate it into their current system
• Provide support services

Solution:

Comco accepted this challenge and worked with the management team of AgState to pin point the current issues and determine a list of future needs. Technical site visits were conducted by Comco technicians to evaluate the issues first hand and develop a plan. The updates and fixes as well as the expansion programming was added to the control system with very little interruption to production.

Result:

AgState has a control system that is customized to their needs.  Also, they now have the support services available any time they need adjustments or have questions.

Update:

After supporting the hybrid control system for almost 2 years, Comco was able to replace it with a completely automatic front to back Comco control system. This new Comco system provides:

• Cross contamination prevention
• Automated routing from source to destination
• Remote accessibility
• Manager utility screens to set security permissions for the operations team,  equipment setting such as idle timers, clean out timers, alarm setpoints etc.
• Integrated monitoring of bearing temps
• Hardware (Allen Bradley PLCs) were reused wherever possible to save expense for the customers
• Automated fan control
