  3. Windows 8 and U90Ladder

    in Jazz, M91 PLCs and U90Ladder

    Posted

    Dear Sir,

    Thank You for quick answer.

    I am using 64 bits version of Windows 8. I am reinstalled prolific driver (from https://unitronics.exavault.com/share/view/1j3m-glck37nv-1lljo5h ) as You recommended, but situation is the same.

    In the Device Manager, Prolific USB-to-Serial Com Port (COM5), set correct. When I checked with "Check PL-2303 chip version v1002" com port 5 I get: This is a PL-2303 RA chip.

    In the U90 Ladder I set Baud rate-9600, Parity-None; Stop Bits-1; Data Bits-8 and Flow Control- None, com 5 (the same configurations are in Prolific settings).

    Then I trying to get PLC settings, I am got error- (2) U90Ladder:

    Communications could not be established due to one of the following:

    *Cable connections are not secure.

    *Timeout is too short.

    Incorrect communication settings.

    Check your cables and communication settings and try again.

    Hi,

    This is my first topic in this forum I have question about U90 Ladder and windows8. I cannot connect my Laptop to Unitronics M91-2-R34 (checked all possible variations of ports, baud rates, stop bits and so on). User Account Control (UAC) settings is turned off. I am using Prolific USB to Serial converter. This converter can work with windows 8. Is U90 Ladder working with windows 8? Perhaps somebody can help for me...
