DB number is the input parameter of FC35, It is called in FB202.See the attachmnet.For example DB202 is what you want.See which DB assigned to each control loop. AttachmentHD.zip (233 Downloads) |

To see what are the all parameters related to FB41 ,please check it in the online manual of STEP7 or attachment(FB41.pdf). To see what are the meaning of Gain,Ti,TD and TM_LAG please check the following link. STEP response of open loop PID algorithm is really important to understand how this algorithm works.
