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
