The start and stop functions change the operating mode of a device. The start function enables outputs and the stop function disables outputs.
Devices can control complex and perhaps dangerous industrial processes. Do not use the start and stop functions until you take the required safety precautions and put required operating restrictions into effect. Refer to the manufacturer's documentation for specific safety precautions. |
The upload function transfers the contents of a device's memory to an OpenVMS file. The download function transfers the contents of an OpenVMS file to a device's memory.
To perform the download function, the memory protect keyswitch must be in the OFF position for all device models. Also, the DAS must log in to the programmable controller. If another user is already logged in the download will fail.
You perform a download function on a Modicon device without first stopping the device. |
