Monitouch V-Series HMI Non-Volatile Memory: Assigning SRAM
Non-volatile memory is essential for storing critical data. It allows for persistent configurations and direct data access of the persistent without having to rely on external media. These advantages come with the Human-Machine Interface (HMI), meaning any external media does not have to be cared for or warrantied.
Every Monitouch HMI comes with more than a hundred kilobytes of Static Random Access Memory (SRAM), whose data is maintained by a coin cell battery in the rear of the HMI. This area is used for Logging and Alarms, but the programmer can also use it for saving everything from recipes to machine configurations. In this blog, we will cover how to assign SRAM to be used as an internal memory device and a simple use case with a Macro.

With today’s medical manufacturers vying for top position in the industry, they are working to meet new market challenges, quickly responding to customer demands and uncovering new opportunities. And one of the critical keys to success – the ability to be more efficient than ever before. So, when it comes to procuring
