1 Purpose of document
This document describes the firmware download process for the equipment ETL600 Rel. 1,
supported by the PC program HMI600.
2 General
The HMI600 supports firmware download for the modules P4LT/P4LU, O4LE and G4AI.
The firmware download gives you the opportunity to update the equipment to the latest release or
to modify a module ordered from stock to the actual release in your equipment.
The automatic release detection in the HMI600 identifies incompatibilities between firmware
versions on the modules in an equipment before the configuration upload or download process is
executed. If any incompatibility is recognized, you will be informed that a firmware update has to be
executed. In this case a configuration download is not possible. The automatic release detection
doesn't detect if you are using the latest release. For information about available releases and
about compatibility between software, firmware and hardware of the ETL600 system please refer to
the document „Compatibility Requirements for ETL600" (1KHW001490).
The firmware of module P4LT/P4LU is stored in a non-replaceable FLASH memory and will be
checked for integrity during the start-up procedure. Therefore, if a firmware download failed due to
a power or communication failure, this will be detected and a so-called "emergency firmware" will
be activated. This emergency firmware supports a firmware download only and is indicated by
sequentially blinking in anticlockwise direction of all LEDs of the module P4LT/P4LU.
2.1 Necessity for a firmware download
The automatic firmware download has to be used in the following cases:
1. Update already configured equipment with automatic backup and restore of the configuration.
Typically, this might become necessary when firmware versions are available with new
functionality.
2. Update non-configured equipment with download of the configuration settings from a file.
Typically, this might become necessary after the assembly of the equipment.
3. Modify equipment if the configuration download (HMI600) detects an incompatibility.
Possible situations are if you download a configuration to virgin equipment or the HMI600 has
extended functionality, which is not available on the firmware in the equipment.
4. Extend the equipment and the HMI600 informs you about firmware incompatibilities.
5. Exchange a module and the HMI600 informs you about firmware incompatibilities.
6. If all LEDs of the module P4LT/P4LU blinking sequentially in anticlockwise direction. In this
case a corrupted firmware of the P4LT/P4LU itself was detected and an application is running
which allows a firmware update only.
2.2 Risks of a firmware download
The firmware download procedure should be performed exclusively by instructed service
personnel. The operator is not allowed to perform this operation.
Caution
Caution
Language:
EN
ACTIVATING A FIRMWARE DOWNLOAD WILL CAUSE MALFUNCTION
OF THE PLC-LINK.
NEVER SWITCH OFF THE POWER TO THE EQUIPMENT WHILE A
FIRMWARE DOWNLOAD IS IN PROGRESS.
Violation of this rule will produce a system with incomplete firmware on the
modules of type G4AI or O4LE, so that it will not work anymore. If this should
happen, you'll have to send back the affected board for repair, specifying the
firmware version you need.
