PLC Delta Read Modbus RS-485 ( DPMC530 )
Hello guys!
I have a project to read PowerMeter ( DPM-C530 and DPM-C520 ) using PLC Delta DVP28SV. I am using a counter function with M1013 ( 0,5s ON ) to increase a counter block. When the counter turns to the different value, it will SET the output M100 – M120. If I use M1013 and read two more PowerMeter, it will take 20s, maybe it is too long for real-time data collection. But when I use M1012 (100ms ON) to increase Counter, The Modbus Register will has wrong value from the wrong Parameter ( because the Counter is missing the Output Coil while increasing ). Is there any solution to solve my problem? Thank you for attention!!
Hi,
Can you share your program ?

You can use internal timer instead of system bit. May be it will help you.
Good Luck.
