I've configured a PID loop in my PCS 7 project and generated the WinCC faceplate. However, when I called up the faceplate, it doesn't allow me to change the operating mode or change the setpoint or manipulated value (all grey out). Attached are some screen shots: 1. PID problem 1.bmp: Both the "Mode" and "Setpoint" field don't allow me to change settings; according to the manual, there should be a drop down button on the right side of the field, but I couldn't make this button appear even though I've set the bit Q_SP_OP and AUT_ON_OP. Also note that the fields SP and MAN are grey out on my faceplate. In the manual, these two fields should have white background and allow the operator to change values. 2. PID problem 2.bmp: Note that I've set the PasswordLevel to "Process controlling". 3. PID problem 3.bmp: Note that I've created an user "supervisor" and assigned authority levels up to 8 and with the authority level "Process controlling" activated. However, after I've logged in using supervisor, I'm still not able to change the values on the faceplate. The version of PCS 7 I'm using is V6.1 and the PID block used is FB61. Does anybody know what setting is needed for the faceplate to work?

Hi Tagolover, Thank you for taking the time to reply. I've actually had the MANOP_EN and AUTOP_EN set to 1 before and the faceplate was not working. Can it be something in WinCC that's preventing the faceplate from working? Anyway, I was logged on with "Process controlling" authority but that didn't help. Maybe you can take a look at all the I/O's in the PID block from the attached PDF file and see if you can identify the problem. Thank you again for helping out! Best regards, Eric

Have you tried with user authorization level "Higher Process Controlling" ? |

Hi Phantom75, Yes, I've setup authority level up to 8 (Advanced process controlling = level 6), anymore ideas? Thanks
