Hi, i cannot confirm if my HMI is already dead or not. History: Upon machine startup the HMI fail to display anything (black screen), the partner PLC is functioning ok. Supply to the HMI is also good, after few hours of not doing anything the display finally emerge. The HMI runs for about 2days and now its completely not displaying anything. I tried connecting my computer and runs GT designer 3 to check if i can communicate / download the HMI program, unfortunately i got an error communication message which i did not get before when it is completely fine. Green light at the back of the HMI on the 100M is observe to be functioning and random green light flicker under SD/RD. Is my HMI already dead? Inputs are much appreciated, thank you!

Hello, I have use case for my FX5U-32M PLC controller that has an analogue output module that is hooked up to a 10V trigger SSR heater. I want to use the PID function output (MV) to control power output of the SSR heater (0 - 100%). My measurement value (PV) is an analogue input from a temperature sensor between (0 - 400C). With a temperature set point somewhere between that. I figure that as long as I know the percentage power I need to use,  I can use a pulse width modulation to trigger the SSR heater for the set amount of time each sample cycle.  I think desired output for the MV would be at high deviation under the setpoint that my power output would be 100 percent while lowering when approaching setpoint. But what I don't understand is how I would either guarantee that the values for the MV stay within that range.  Is it the case that I should just tune the PID to output sensible values but not worry too much if MV is in the 0-100 range and then anytime my MV is above 100 just output 100% on the SSR and vice versa for MV under 0? Or am I just approaching this the completely wrong way? Thank you in advance  P.S Currently my PID function block has the Integral and differential actions set to 0. I am experimenting with the standard PID function block with the proportional gain to see the relationship between deviation from setpoint and the proportional gain, What I don't understand is why when my deviation from set point is 13, the proportional gain is set to 1000% then I am seeing an MV of 130, rather than 13000 is there something I am missing about what the proportional gain actually represents.    

good day! I would like to put some ascii code in a device: D3000..D3009 has to be filled with 0x5F54 0x4F5F 0x4150 0x6F73...  ("_TO_APos")  When I fill it using an ascii-input-field in the designer and press "enter" it works. But I would like to put this text automatically in D3000 and following register, when the user press a switch-object. I tried with an 10 actions  "keycode" but I don't see how to say that the key code shouls be saved in D3000. Can somebody tell me the best way to fill more word devices with only one object switch? Thanks in advance   MEBoerner
