Firmware is the software that resides in the controller. Each RMC is shipped with the latest version of firmware. Delta regularly releases new versions of firmware that include bug fixes and support for new features.
Each command topic in the RMCTools help lists the firmware version required for the command. Other topics may also specify which firmware versions support the feature.
To update the firmware, the RMC must be connected to the computer running RMCTools via USB, Ethernet, or the RS-232 Monitor Port. The second serial port on the RMC75S will not work for updating firmware. To update firmware via Ethernet, the Allow updating firmware over Ethernet box must be checked in the Ethernet Settings Page.
To update the firmware in the RMC:
Go to Delta's website at https://deltamotion.com.
On the Downloads page, find the firmware for your module, and save it on your computer.
In RMCTools, go online with your controller.
In the Project pane, expand the Modules folder, double-click the module you wish to update and click Firmware. For the main firmware, the module will typically be the CPU.
In the Control Program section, click Update Firmware. This will open the Firmware Update Wizard. Follow the instructions to complete the firmware update.
Backing Up Firmware (RMC75/150 Only)
As part of the firmware update process, the firmware in the RMC75 and RMC150 can be backed up before the new firmware is downloaded to the RMC. Delta recommends backing up the firmware in case you need to revert to that firmware version. To back up the firmware, use the Firmware Update Wizard as described above. Before the download occurs, you will be given the option of backing up the firmware.
Firmware Base Version
Each firmware release made for the RMC is identified primarily by a two- or three-part version number such as ”3.30.0”. Each firmware release may include more than one actual firmware image, with each image having a separate Configuration ID. When a controller is loaded with firmware, RMCTools chooses the appropriate firmware image to load into the controller.
Special Releases
In some cases, Delta will release firmware that differs in some way from the generally-released firmware. These are designated by an additional special release code. For example, the ”S4” special firmware has ”S4” append to the version number, as in ”2.72A-S4”. For more information on the S4 special firmware in particular, see the Firmware Compatibility section below.
RMC75 Firmware and Hardware Compatibility
The RMC75 firmware has the following hardware compatibility limitations:
| RMC75E | |
|---|---|
| Hardware Version | Supported Firmware |
| RMC75E 1.x | 1.00 or newer |
| RMC75E 2.x | 3.67.0 or newer |
| RMC75E 3.x | 3.72.0 or newer |
| Version | RMC75S | RMC75P | ||
|---|---|---|---|---|
| 2.1C or older | 2.1D or newer | 2.1D or older | 2.1E or newer | |
| 3.00 and above | - |
|
- |
|
| 2.72-S4 to 2.99-S4 | Note 1 | - | Note 1 | - |
| 2.30 to 2.71 | Note 2 |
|
Note 2 |
|
| 1.00 to 2.21 |
|
|
|
|
Note 1: These firmware releases are reserved for patch releases for the older RMC75S and RMC75P controllers, which cannot support new features and are therefore not included in the 3.00 and later releases. This firmware is assigned the ”S4” special release code.
Note 2: These firmware releases support all RMC75 controllers, but the older RMC75S and RMC75P controllers do not support all new commands.
