Issue
If I have downloaded a project from Vijeo Designer via File System USB memory stick to an HMISCU or XBTGC, the PLC does not start in RUN in subsequent power cycles.
How can I ensure that the PLC starts in RUN after power cycles when I download with this method?
Product Line
EcoStruxure Machine Expert v1.1+ / SoMachine v3.1 and higher
Harmony HMISCU and XBTGC
Environment
PLC Logic Builder and Vijeo Designer HMI configuration software in Windows
Cause
The flag for startup in the XBTGC and HMISCU is managed by a configuration file in their file system which can only be set with a cable (Ethernet or USB) download.
This flag is not settable using USB memory stick File System method of download.
The configuration flag is only set when these 3 conditions are met with a Cable-method download:
1) The download method is from the Online -> Multiple Download window
2) The "Start all applications after download or online change." checkbox is activated with a tick mark
3) The "<name>: HMI Application" is activated with a tick mark
This is not possible from Vijeo Designer's File System download.
Resolution
The method to always have the PLC start in RUN mode, regardless of Download method is to make a configuration change in Vijeo Designer by way of creating an Action in Vijeo Designer to write a non-zero value to a Variable with System Property @prop:0 on startup in order to guarantee the PLC starts in RUN after each power cycle.
Follow these two steps below to achieve this:
1) Create a new external variable INT in Vijeo Designer and address it as @prop:0. In this example, the Variable is named "RunController"
2) Create an action to write a non-zero value to the variable on startup.
[Other Useful Properties]
Here is a list of all driver properties for the HMISCU and XBTGC series HMI combo controllers that can be used as an Integer variable in Vijeo Designer:
@prop:0
@prop:1
@prop:2

Here is a list of all driver properties for the HMISCU and XBTGC series HMI combo controllers that can be used as an Integer variable in Vijeo Designer:
@prop:0
- Read/Write access
- Writing any non-zero value will put the controller application in RUN
@prop:1
- Read/Write access
- Writing any non-zero value will put the controller application in STOP
@prop:2
- Read-Only access
- This returns an integer that is associated with the state of the controller
- 0 - N/A
- 1 - Running
- 2 - Stopped
- 3 - Error
- Read-Only access
- This returns an integer that is associated with the Error state of the controller
- 0 - No Errors
- 1 - Error
