Product Description:
The 2ME915.90-1 Controller is the creation of B & R Automation and it comes under the series of System 2010 Controllers. The module can be easily integrated into existing automation networks and it provides precise operations.
The 2ME915.90-1 controller is designed to work with specific processor modules such as CP10x, CP2x0 and MP100 and it won't work with unsupported CPUs. It has a 2 MB FlashPROM memory which is non volatile and retains data when the power is off. It is used to store system firmware, configuration settings or application code. Its battery has a voltage of 3 V and its capacity is 950 mAh which indicates its backup time. The physical footprint of the module is 103 x 32 x 122 mm which shows it is relatively compact that makes it suitable for DIN rail mounting or tight industrial enclosures. It uses both a battery and a capacitor to preserve buffered RAM during power loss. It can handle short voltages through capacitors while the battery covers longer durations. It can be stored in a wider temperature range from -20 to +70 °C when the battery is removed which makes it robust against extreme environments.
The 2ME915.90-1 controller comes with a LED which shows the status of FlashPROM programming which gives the user visual feedback and helps avoid interrupting critical processes during a write operation. The system working memory is 2MB which is used for temporarily holding data during operations. For user defined functions such as custom logic, counters or temporary data it has a separate memory of 2MB. The controller runs on PCC software which is a proprietary platform that supports deterministic real time operations and interfaces with development tools.
Frequently Asked Questions about 2ME915.90-1:
Q: Why is gold foil capacitor used alongside the battery in 2ME915.90-1?
A: The gold foil capacitor ensures rapid energy delivery during brief power losses. It complements the battery for longer-duration memory buffering.
Q: How does the LED display improve operation safety in 2ME915.90-1 controller?
A: It provides real-time status of FlashPROM programming. This prevents accidental disconnections or write interruptions during critical updates.
Q: How does PCC Software enhance the 2ME915.90-1 controller performance?
A: PCC Software enables deterministic real-time execution and seamless development tool integration. It ensures precise task scheduling for automation control.
Q: What is the advantage of the write protection switch in 2ME915.90-1 controller?
A: The switch prevents unauthorized or accidental overwrites to the firmware or memory. This feature enhances system security and stability.
Q: Why is dual 2 MB SRAM memory used in this controller?
A: One 2 MB memory serves system functions, the other supports user applications. This separation improves efficiency and application customization.
