Hello. Suppose, from a certain Modbus device in the 2nd register, a number comes to me. But I want to get the sine or cosine of this number and give the resulting value to the OPS UA server. Can I perform mathematical processing in this OPS UA server? If so, how?

Hello,

Input Registers and Holding Registers allow you to perform linear scaling using a multiplier/factor and an offset on values read from devices. These parameters can be configured in Input Register Properties and Holding Register Properties dialogs. More complex mathematical operations such as using values from devices as inputs of sine or cosine functions are not supported.

Thank you very much!
