[Reset to factory settings]

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
