# SYPTPro V02.08.03 Release Notes

Issued: 25th April 2024. Updated:

## System Requirements

SYPTPro may be installed on Windows XP (SP3) or later, however it is highly recommended to use Windows 7 or Windows 10. SYPTPro requires about 200MB of disk space.

## Installation Notes

- If upgrading from V2.6.x or earlier the old version must be uninstalled. You will be prompted to uninstall during the install of this newer version.
- If you wish to downgrade to an older version (prior to V2.7.0) you MUST uninstall the current version first. Older SYPT installers will not detect V2.7 or later having been installed.

## Changes in version V02.08.03 (from V02.08.02)

- Updates to images and branding and some minor text corrections.

## Changes in version V02.08.02 (from V02.08.01)

- Added support for additional Digitax HD variants.
- Fixed an issue where SYPT would freeze showing the splash screen when certain Windows themes were chosen or high-contrast mode was active.
- Corrected issue where option number in device details printout was always zero, also removed meaningless "Target" item from printouts.
- Fixed an issue where if you altered comms settings on the startup dialog (under the "Go online" choice) the settings may not take effect.
- Winflasher update (V3.11):
  - Prevent old firmware being programmed to SI-Applications modules with newer flash memory (tech note T190505).
  - Fixed bug from V3.10 which prevented programming bin files to SM-Applications modules
  - Fixed filename text entry limitation.

## Changes in version V02.08.01 (from V02.08.00)

- Increased the default programming timeout used for new projects. This is required to overcome potential timeouts mid-way through programming a large program to an SI-Applications Compact module. Existing projects won't be altered so if you experience timeouts whilst programming the module then you'll need to manually adjust this by going to Run > PC Communications Settings > Settings > Advanced and increasing the Program Timeout value from the default of 500 to 2000.
- Fixed problems installing/upgrading if a newer version of the Microsoft Visual C++ runtime is already installed on the PC.
- Updated the Digitax indexer support library to fix a current scaling issue in the homing current limit block (_IndexerLimHomeBGrnd).
- Minor changes in help file.

## Changes in version V02.08.00 (from V02.07.00)

- Added support for SI-Applications Compact module which fits into any of the slots on a Unidrive M type drive. This module is otherwise the same as SI-Applications Plus.
- With the new SI-Applications Compact module it is now possible to access it via an MCi210 or SI-EtherCAT module (providing the latest firmware is used in the interface module). The old SI-Applications Plus module may be detected but it will not be possible to communicate with it other than via the built-in drive Ethernet port, serial RTU port on the drive or CTNet.
- Ethernet network scanning mode for discovering drives accessed on a different subnet via a gateway (such as EoE - Ethernet over EtherCAT). This avoids the use of broadcast messages, which are typically blocked by gateways, and instead probes an address range.
- Support for Unidrive M751/753 drives and Elevator drives.
- Upgrading from V2.6 or earlier has been improved.
- Help file and user guide updates.

## Changes in version V02.07.00 (from V02.06.13)

- Added new SI-Applications functions for User Mode Ethernet communications (requires V2.10 or later SI-Apps firmware and V1.7.0 or later on the drive's Ethernet interfaces).
- Updated the complier for SI-Applications to use a Unidrive M parameter database when determining if a parameter references (e.g. #1.21) is integer or floating-point.
- When scanning for drives, any Unidrive M drives that don't have a SI-Applications module fitted will now be ignored. If you want to revert to the old behaviour of showing these drives then use Tools > Options and check the "Show newly discovered drives that are not programmable" option.
- Fixed compiler issues under Windows XP.
- Fixed runtime error with the SSRAMP function block.
- Help file now has separate section for SI-Applications module.
- Updated Unidrive M porting information (please ensure the SI-Applications Plus module firmware is up-to-date)
- The "Convert to Unidrive M" tool will now convert SM-Appplications, SM-ApplicationsLite, SM-ApplicationsLiteV2 as well as SM-Applications Plus modules into SI-Applications Plus on a Unidrive M.
- Updated Winflasher to fix issue where updating the system file of an SI-Applications module was reported as being completed prematurely.
- CTNet drivers for Windows 10 x64
- Drivers for the CT USB to RS485 converter lead (FTDI) are now included for Windows 7 or later.
- Improved installer.
- Other minor fixes.

## Known Issues / Troubleshooting

- Attempting to install an earlier version of SYPTPro (<= V2.6.13) without first uninstalling the current version may result in a corrupt installation. Please uninstall the newer version first.
- If you have a Unidrive M / Digitax HD drive and are connecting via the drive's Ethernet port but SYPT doesn't detect the drive or the SI-Applications module then ensure that the Modbus protocol is enabled. For a Unidrive M700, parameter 04.15.001 must be set to On (1).
