How to use FB41 (CONT_C)?

Ors Posts: 1 Rating: (0)	Dear All, I have to control the pressure of a liquid with a Yaskawa V1000 inverter. The inverter is connected with Profibus to a 317-2-DP CPU. The inverter's frequency reference is a Word (2 Bytes). If I set "5000 decimal" in that register, then the motor runs on 50.00Hz (there is no negative value in the register). The pressure sensor's measuring range is "0...600bar", and it has a 4-20mA output. I have to set the pressure of the liquid in 0.1bar unit. I think I should use FB41 (CONT_C), but I dont know how exactly. Please help me. Thank you in advance.

First about the other parts of your design such as transmitter selection/ inverter handling contact expert in those fields.For FB41,Only read the online manual in STEP 7 plus my clustered posts here: HD PID Control Package - FB41 Samples try and Update in case of any problem
