The only problem that might occur during a running upload is the tag values may change while the machine is running, as the upload will take longer than one scan of the program, so the offline data might not compare
IE - temperature setpoint doesn't match process value but the heater isn't on or called for because when the BOOL tag for HeaterOn was uploaded it was OFF, but when the DINT tag for HeatPV was uploaded it dropped to where the heat should be on.
Hi, it is a AB controllogix. With upload I mean getting
The project from the plc to the pc. Do you need to put it online, stop,etc.
Should I stop the equipment ? What would be safest procedure?
Thanks for the help
Uploading from the PLC to the PC is required to go online with the controller. No need to stop the equipment for an upload.
