DL205 Frequently Asked Questions
| Question | Why can I not get any Control Output from my PID loop? |
| Answer | Most likely you haven't entered a high limit for your Control Output in the PID setup. The default is 0 and the maximum is 4095 binary. Your must enter something in this field (Word+31) from the PID setup or from ladder. You should also check your Control Output word (Word+5) to see if you are actually getting Control Output. If this value is changing then make sure you are writing this value to the physical output device. This will most likely be an analog card or Time-Proportioning ladder for a discrete output point. |
