Flash scheduling
ControlFLASH Plus
determines the flash scheduling depending on the devices’ flashing configuration, their topology, and parent-children relationships.ControlFLASH Plus
version 2.00.00 or earlier can flash of up to 20 devices concurrently based on their topology except for the following cases:- Parent/children devices are updated sequentially. First, the parent devices are flashed concurrently, and then the children devices are flashed. Children devices may be flashed concurrently depending on their topology.
- Peer devices on linear buses are updated sequentially. Examples of linear buses include Ethernet Linear/DLR (not Star) and SERCOS.
- Devices with multiple active ports in a chassis are updated sequentially. An example of a device with multiple active ports would be a 1756-EN2TR with two network connections.
From version 3.00.00,
ControlFLASH Plus
supports enhanced concurrent flashing. This capability is turned on by default. The enhanced concurrent flashing extends the sorts of devices that can be flashed concurrently compared to earlier versions of the tool. For the devices whose reset mechanism can be controlled by ControlFLASH Plus
, they can be flashed concurrently by holding the reset:- Parent/children devices are now flashed concurrently by holding the reset.
- Peer devices on linear buses are now flashed concurrently by holding the reset.TIP:Future versions of the PowerFlex® firmware will allow for concurrent flashing.
For the devices whose reset mechanism can’t be controlled by
ControlFLASH Plus
, they are still flashed sequentially:- Parent/children devices (For example, 1756-DNB)
- Peer devices on linear buses (For example, PowerFlex Drives)
