Hi everyone, Today I created an algorithm in the PLC of the pulp plant where I work at, what I need to do was to match the flow of a screw pump and a centrifugal pump, I matched my formulas but when I uploaded the rung to the PLC it does the calculation and the number of bits are correctly shown in the CPT block and in the Local:6:O.CH5Data when I go online, but the output of the module stays fixed in 5.24mA, I was searching in the forum and I found that it is a common issue to stay fixed in 12mA when you do configure the clamps wrong. I'm using a 1769-OF8C Module and the output is wired in the channel 5, all of the other channels are working perfectly.
My channel is enabled, Output Range: 4mA to 20mA, Data Format: Scaled to PID(I left it this way because all of the other outputs are configured like this, I even calculated the formula to match my pumps using 0 to 16383, I think this is to match the resolution of the module) Hold for initalitazion is disabled and the clamp limits are low:0 high:16383. The Controller is a 1769-L32E CompactLogix5332E revision 19.11
I have configured analog outputs before with this PLC with no issues, but I can't seem to find whats going on here:smas:. Can any of you PLC gurus help me?
