I am trying to determine or find any figures that could assist in obtaining the lifespan of a single output of a 1756-OB16E output card. I have a signal sending 400 pulses a minute to an output. I am starting think about when this card or output may need to be replaced before failure. I was given a MTBF range by Rockwell for the card itself but they could not expand on the likelyhood of the output failing exponentially due to the rapid signalling. I could also not find anything in the manual itself that could provide me with an idea of longevity, I could be missing it? Also with this project I experienced something odd with the originally scoped hardware, a solid state 24VDC relay (700-HLS1.) By measuring the resistance I was able to see that the relay should have been opening and closing but the signal was not being received. So, I swapped the solid state relay for a mechanical relay and it worked fine. I was curious if the leakage could have an effect on this. The problem with the mechanical relay is that the life is dramatically reduced to about a month for this installation, life for the relay is shown at about 10,000,000 actuations. I was hoping to have this working with a little longer life expectancy. If anyone has any experience / tips / or suggestions it would be much appreciated! PG
Hi Good Day, I need a suggestion, I have an omron encoder, encoder counter meter (K3NC-NB1A) and communication card RS-232C 25pins (K31-FLK1). My question is, what is the best omron software to read and manipulate the data from the encoder (I have CX-one software but I only use CX-programmer). I want to capture the encoder pulse and convert to velocity, acceleration, deceleration and also energy absorbtion. I have to use mathematical formula such as two times differentiation. I also need to show grapf and display final result that is energy absorbtion reading. Or is it much simple if I use VB / labview / java software? Thank you in advance
Hi I need to program my fatek fab Plc with the following : . I need to detect between a single long input or a repeated second pulse. The idea is to control a window blind with two outputs of the Plc and two inputs (one for up, from a up switch and another for down from the down switch). the blind should go up until I maintain the key pressed. But when I make a repeated two pulse on the key it should go up automatically during a certainly define time (enough to completely open the blind). The same for the down direction. I need help on that.
