DC523 1SAP240500R0001 ABB Module controller sensing device

Description

Whether the DC523 solution without battery has advantages depends on your application. In designing your system, you need to consider several
A place with or without advantages

Possible benefits
An obvious benefit of using battery backup without memory is the freedom to maintain the battery. In order to be able to
To operate without batteries, you need a PROM device installed in the system – or a
EPROM, EEPROM and flash memory, these devices can store program logic, hardware configuration and
The value in the register is DC523, and the CPU can be configured to read data from PROM to RAM at any time when the PLC is powered on
In memory
Possible adverse conditions
The data is not automatically stored in the PROM. In order to store this information, DC523 must stop the PLC and then use the programming
The processor tells the CPU to write the contents of the current PLC (RAM) memory into the PROM device. For some users
The operation without memory battery is not satisfactory, for example, in many applications
For example, the current position in the box filled with a certain material or some data for calculation of a certain part are collected
These frequently changed data will not be automatically stored in the PROM device,
The data is only stored in RAM. Therefore, when the PLC is powered off and there is no backup battery for RAM memory
The data will be lost
However, in a system without a storage battery backup, one way to retain data is to send the data over the network to
In the computer hard disk where data is stored, static data (unchanged data) is still stored in RAM memory
, such as mathematical operation constants or information tables, can be stored in the PROM during initialization and automatically when the PLC is powered on
Is written back to RAM
Another thing to consider in DC523 is that if you want to change the program (or hardware configuration), someone must remember and change the information
Write it to the PROM device. If this step is forgotten, the change is only stored in RAM, and there is no memory
These changes will also be lost after the battery backup system is powered down
