So you have controls on your pneumatic transfer system that has been in operation for 15 to 20 years now and it has been reliable. With the exception of a light bulb or a switch here or there that needed to be replaced, the system has performed with few hiccups.

But what would happen in the future if a component in the control system faults out or doesn’t boot back up after being shut down?  Or what if a power outage at the plant occurs? Can your personnel get the system back online?  Do you have a backup of the PLC program or replacement spare parts just in case? Can you find the current drawings and documentation for the control system? If you don’t know the answer to these questions, you may need to consider upgrading your controls.

Upgrading your control system to the latest technology and features may seem costly and difficult.  It’s the quintessential “if it ain’t broke…don’t fix it.”  However taking the risk of not being able to get your system back online due to outdated and/or obsolete parts can be a big gamble.

A new PLC (Programmable Logic Controller) and HMI (Human/Machine Interface) can go a long way.  Coupled with replacing pressure/vacuum switches, which tell you only made or not made conditions, to pressure/vacuum transmitters, which give continuous actual data, will give you the latest technology in industrial automation and provide a clearer picture into your plant’s process.   Also other data, such as temperature, can now be transmitted/reported in a much more economical way than it could 20 years ago.  By upgrading, not only will you have the ability to monitor system performance and make adjustments but you can also display and record your process’ times and variables.
