Reset to factory settings


Recommended Posts

Hi Kris9880,

 

What type of Unitronics PLC do you have? Each PLC has an option for BootStrap mode and Stop Mode. Instructions on how to get to these modes vary between controllers. Within these modes, the program stops, and the PLC communication settings are reset. 

 

What are you attempting to do in this mode?

 

Thanks, 

 

Dan.

Hi,

 

 I have JZ20 T18.

 

 I have communication problems  after i download a program with SI140 = -1 (STX  parameter"no start of text " RS232).

 

When I set de communication parameter on de plc to default ,and i go to BootStrap  "key "i" + "7" with power up, then i have a connection with de plc.

 

After i do an upgrade of OS  (uprade wel done)  and de plc restart , i have NO Connection U90 >plc.

 

Is it possible for delete de program without pc(U90). with key combination or dipswitches ...

 

I want a clean empty plc.

 

Thanks,

Kris
