Other Userful Functions Real-Time Clock with Backup A real time clock (RTC) has been built in all PR models. No matter whether the PLC is switched on or off (up to 20 days when power is off), the RTC will keep accurate time. It provides 7 units of time data-week, year, month, day, hour, minute and second. For applications that require the RTC to continue running more than 20 days after power off you can purchase a PR-Battery accessories or insert a 3V on-board lithium battery in the inner battery socket (Only for PR-24 Series).
Users can take advantage of the real time clock to do 24 hour controls throughout the year (for example, businesses or factories can switch lights on and off at set times each day, control gate access, and do pre-cooling and pre-heating before business or operations begin). Large Program Capacity (Largest in its class) Program capacity 1024 Blocks/13KSteps PR-18, PR-24 2 times larger memory capacity Your PLC needs enough storage space to handle the amount of 512 Blocks/5KSteps tasks you are going to assign and it doesn’t hurt to have a little extra for future needs. PR-12, PR-14 Rievtech Micro PLC is equipped with abundant memory capacity.
PR-6, PR-12-E 64 Blocks With 1024 blocks (13k Steps) (For PR-18, PR-24) of logic controls programming, complex PLC programs can be constructed without much restriction. Data Logging to a Micro SD Card Data–logging is the process of collecting, in real time, determined process parameters such as conditions, values, as well as the time that said information is collected, or noted. Having historical data 1010101 1010101 Memory Card microSD 2GB available to you when trying to find or correct an issue can make a huge difference. PR-MEMORY allows you to log up to 2GB of tag *.txt data. This data is saved in .txt format on a removable micro SD card and can be easily downloaded to your PC.
