So, where I'm trying to fight with an TSX3710DC PLC. I'm using the cables TSXCUSB485 + TSXCRJMD25 and PL07 v4.5Pro.

I installed a lot of drivers to recognize the cable on windows XP (TSXCUSB485_Driver, MODBUS Serial) as I saw in some manuals, but I still not communicating with PLC, I think that is missing some points to do but I don't know what. Can someone give some help? Like communication parameters, address that I should try to use, drivers that can be missing, anything that can help please. Thanks Again.

IEC programming software for Micro and Premium PLCs. Optional PL7 Diff software compares and identifies differences in application files to ensure process consistency and recover from unauthorized program changes. Designed for setting up Modicon TSX Micro and Modicon Premium PLCs.

Working on a dumbwaiter that has a Modicon TSX nano plc with a Square D reversing contactor. The unit will not run. Have already checked and/or bypassed all the interlocks and still cannot get the unit to run. Can manually trip the contactor to make motor work. No error lights on PLC. Looking to up grade PLC. Paperport 11 serial number.

Do not have copy of PL7-07 to get copy of program off unit. Cannot find a copy anywhere. Do not want to have to rewrite program, but looking like that is what I will have to do. Any help or ideas. Already contacted them and talked to the Tech engineer. They no longer support or sell either the software or cable. He suggested ebay, but the software is not being sold.

I assuming that if they do not sell it or support it, I can have a copy anyway I can get it. Yes the PLC run light is on. No error lights. Bypassed the door interlocks and safety travel limit stops (TLS - NC, DI- NO) still no operation. I see the I/O lights come when floor call button depressed. I do Have one Output light on, Think 0.

I can manually trigger the reversing contactor and the motor will runs both directions. Next step would be look at the program logic in the PLC. I xcan buy a new updated PLC that uses free available software and a standard IO cable, but that means writing the PLC programming from scratch. Have already talked to the engineer at Automation direct for there basic PLC that would work, their software is free for download and used a standard DB9 to RJ12 cable.
