EL-O-MATIC EL100 A2.1气动执行器
产品详情资料：
EL-O-MATIC EL100 A2.1气动执行器无内存备用电池的操作使用无电池方案是否对您有利取决于您的应用。在做出决定时，需要考虑各种优点和缺点。可能的优势在没有备用电池的情况下运行的明显优势是，您无需维护电池。为了能够在没有电池的情况下运行，您需要在系统中安装PROM设备——EPROM、EEPROM或Flash PROM。这些设备可以存储程序逻辑、配置和寄存器值，而无需备用电池，EL-O-MATIC EL100 A2.1您可以配置CPU，以便在每次PLC通电时将PROM的内容读入RAM存储器。可能的缺点信息不会自动存储到PROM设备中。要存储信息，必须停止PLC，然后使用编程设备告诉CPU将当前PLC（RAM）内存内容写入PROM设备。这一要求可能使许多用户不希望进行无电池操作。例如，在许多应用中，重要数据被收集并存储在RAM寄存器存储器中，诸如正在填充的储罐中的当前材料水平或生产的部件的运行计数等数据。EL-O-MATIC EL100 A2.1
EL-O-MATIC EL100 A2.1Operating Without a Memory Backup Battery Whether it would be to your advantage to use a battery-less scheme depends on your application. There are various advantages and disadvantages to consider in making your decision. Possible Advantage The obvious advantage of operating without a memory backup battery is that you are freed from the need to maintain the battery. To be able to run without a battery, you need to have a PROM device - either an EPROM, EEPROM, or Flash PROM - installed in your system. These devices can store program logic, configuration, and register values without the need for a backup battery, and you can configure your CPU to read the contents of PROM into RAM memory each time the PLC is powered up. Possible Disadvantages Information is not stored to your PROM device automatically. To store information, you must stop the PLC, then use a programming device to tell the CPU to write the current PLC (RAM) memory contents to the PROM device. This requirement may make battery-less operation undesirable for many users. For example, in many applications, important data is gathered and stored in RAM register memory, data such as the current level of material in a tank that is being filled, or a running count of parts produced, etc.EL-O-MATIC EL100 A2.1
