Thanks for the reply Mac41. I understand now that I need to have a processor to write to the SD Card then, the program is transferable. However, in my case, I don't have a 5069 processor available to make the transfer. I only have a 1769 series at my disposal. ------------------------------ Paul ...

Can an offline program be copied to an SD Card then installed in a 5069 processor and then run? Recently I was on a project that required several changes to a program. When I tried to write the program to the SD Card the load/store function was grayed out. I pulled the SD Card and found a 16 GB card ...

Recently I replaced a L30ER processor with a new L30ER. The I/O remained the same and was working before the processor change. The reason I replaced the processor was the SD card slot was not working. The processor would not recognize a card when it was in the slot. Moving on, after installing the processor, ...

Thanks Barry. The loop does not have feedback indicating the actuators position. I have tried the IPID function using the auto-tune feature with no real improvement. ------------------------------ Paul Frigo ------------------------------

Thanks for your input Daniel. I have tried varying the Integral from 0.0001 to 1000.0 with no change in the loop output when the PV-SP difference is large. ------------------------------ Paul Frigo ------------------------------

I am having an issue with a PID heating loop. When the PV is dramatically lower than the SP (PV=1200F, SP=1500F), the output goes to 100%. The control actuator(s) has a 30 second travel, I would like to have the output of the loop ramp with in the travel limits of the actuator. I am thinking that PWM ...

Is there a way to enter loop PID gain values through the HMI and pass them to the PLC? When I try to use the move function I get the following error message: Error 1 PID_1.Gains.Kc: Illegal access to function block instance parameter. ------------------------------ Paul Frigo --------------- ...
