RMC70/150 and RMCTools User Manual
To access the Communication Statistics Window:
In the Project pane, select the desired controller. On the Controller menu, click View
Communication Statistics.
The Communication Statistics window displays a number of diagnostic counters that are useful
for monitoring and troubleshooting the communication via the standard port and the Monitor
Port. For more details, see the Communication Statistics topic.
Some of the communication statistics can be cleared (rest to zero). To clear a statistic, select
a folder in the navigation tree, then click Clear Statistics on the toolbar.
The Event Log is also very useful for troubleshooting the communications.
4.5.6. Updating Flash
Updating Flash is the process by which the data in the RMC is stored to non-volatile Flash
memory. In order to save data even when power is removed, the Flash must be updated.
After changing the configuration of the RMC, such as parameters, axis definitions, variable
initial values, curves (temporary curves cannot be saved to Flash), and more, you must
update Flash in order to save the settings through a power cycle.
For RMCs with firmware prior to 3.30.0, if power is lost during a Flash update, all the data in
the RMC may be lost.
Updating Flash from RMCTools
To update flash from RMCTools:
• Go online with the controller.
• On the Controller menu, click Update Flash.
While a Flash update is in progress, the green CPU LED will flash. The Flash update
typically takes 2 seconds on the RMC75E and RMC150E, and 1 second on the RMC75S
and RMC75P. Large projects may take a few seconds longer. The Event Log will log the
amount of Flash memory used.
You may also be prompted to save to Flash when the controller is warm restarted after
changing certain controller data.
Updating Flash via a Command
You can use the Update Flash (110) command to update Flash. While a Flash update is in
progress, the green CPU LED will flash.
Flash Size
The entire RMC project is saved to Flash, including axis parameters, plot templates,
variable table defaults, user programs, and curves. After updating Flash, the Event Log
will log the amount of Flash memory used. The total Flash size is as follows:
Controller Flash Size
RMC150E 1024 KB
RMC75E (1.1G and newer) 1024 KB
RMC75E (1.1F and older)
256 KB
RMC75P 96 KB
RMC75S 96 KB
