Cant communicate with V570 after downloading a program with Protocol FB

[vamalgise]

Hello,

I have new V570, i uploaded a program with nets to read registers from heat meter, 

Probably i made some mistake with COM initialization, now i cant download a program or view the PLC in online mode.

I have completely no clue how to fix it or reset PLC.

Please help me, i cant attach attach my program, because its 20KB bigger than the limit ((

 Thank you.

Hello,

 

If you put the controller into "STOP MODE", you should be able to program a new application into the unit.

 

-Detach power from the PLC

-Press and hold your finger on the screen

-Apply power while your finger is still on the screen

-Once the unit is powered on, tap once on the screen

-After the 10 second time-out, it should enter STOP MODE

-Establish communications with VisiLogic (remember, default baud is 115200)

-Once comms are established, program unit with new application

 

Please let me know if this helps.

I have data tables in my program.

Do I need to download the program first and then the data tables to the plc separately?
