Manville Posted October 31, 2011 Report Share Posted October 31, 2011 I have a Dwyer Series 3000 Photohelic and would like to control a 24volt fan. I am thinking I can use the high level and low level switches to control my voltage. I need a program that will slowly step up the current voltage if the low level is hit and slowly step down the current voltage if the high level is hit. I am extremely new to PLC programming and I have looked through the sample programs and still have no clue. :-) I have an M90-TA2-CAN controller. Any hits or ideas?
