It's an instruction which can be utilized in ladder logic as well as function blocks. The instruction will take input, use input minimum & maximums parameters as well as outputs min/max parameters and convert the output scaling based on them. The primary reason as to why you'd want to utilize this instruction is the fact that analog data will typically be meaningless as it comes into the Programmable Logic Controller or Input Card. The reason being is that the 4-20mA or 0 to 10 VDC signal is generally scaled to the largest scale. On an RSLogix 500 based PLC, this is typically 16384. Once the signal is captured, it's important to either scale it to a percentage of the full range or to a meaningful value. For example, A pressure sensor which reads 0-5 psi, will input 4-20mA & will convert to 0-16384. By using the SCP instruction, one can scale down this value into the psi which will be meaningful for the operator & other users of the system. Do note that the same can be done through the card, but it's usually more difficult to change, keep track of and be reapplied. The mathematical equation of the SCP is straightforward. The equation applied is a linear transformation which maps each value based on the limits as if they were points on a cartesian plane. In fact, one can easily calculate the scaling on a sheet of paper to verify the validity of the scaling factor. Full Tutorial: TBD Check out my Udemy Cognex Class & Save!
