M221 Firmware Upgrade Issue - Machine Expert Basic 1.3 Build 215

[solutions_iems-]

My laptop recently ugraded to Machine Expert Basic 1.3 (build 215) using the software update tool.

Since doing this I have experienced the following problems when using the software with 3 no. TM221ME16R PLCs as follows:

One PLC upgraded OK using the USB port and allowed the "PC to Controller" program transfer using the USB port.

One PLC upgraded OK using the USB port but would not allow further comms (green connectivity progress bar stopped at 86%) so the Ethernet port was used for the "PC to controller" program transfer.

One PLC upgraded OK using the USB port but would not allow further comms (green connectivity progress bar stopped at 86%) and the Ethernet port was disabled so no further comms can be made to the PLC.

Any advice will be greatly appreciated.

Thank you.
