FX3U PID Parmeters

[brinkmann]

FNC 88- PID Parmeters- which are the S3+. For the S3+1 Operation Setting (ACT) How do you enter (from the HMI) bit 0 = 0 for forward operation and bit 5 = 1 set upper and lower limits. All other bits would be at 0. Thanks in advance.

If you aren't controlling the bits separately, then simply build a Hex word with the required bit pattern and write it to the correct data register. In your case, the bit pattern is (from Most Significant bit to Least Significant): 0000 0000 0010 0000 In Hex, that is equal to: H0020 So in your FX3U, use this instruction: |--| |-------------[ MOV H0020 D1 ]--| If you want to control the bits separately, the FX3U allows you to address bits in a word directly, using the following syntax: D1.5, where the number after the decimal point indicates the bit you want to monitor or control. For example: |--| |--------------[ RST D1.0 ]--| |--| |---------------[sET D1.5 ]--| You didn't say what HMI you are using, but most of the Mitsubishi GOT series HMIs allow you to address word bits in the FX3U directly as well.
