Technical support / DM Manipulating
« on: May 14, 2009, 05:42:46 PM »
Hi All, we have successful bi-directional comm. with the f2424 via Modbus RTU. However when I change a value in DM[n] it holds for one scan and then reverts back to the original value. I see the value change on the LCD and in the monitor mode. I would like to use DM's as set point placements for PID control. Wrong application of DM's?
