Melsec F1-20P-E & F2-40M pgm readout ?

[theDave2]

I've got a F1-20P-E hand held programmer attached to a F2-40M PLC and need to read out the program so when this unit goes belly up I can replace it.

The manual for the HHP says to press CLEAR, INSTR, STEP+ to read the elements. When I do this the address readout starts at zero, and only a "K" shows for the instruction and 0 for data, for step 0 to step 150. Got tired of pressing STEP+.

Is there some convention as to where the actual ladder starts ? And how to get there ? When I tried to dial up a step number, the DATA readout changed, not the step #: CLEAR STEP 1 0 0 INSTR did not take me to Step #100, IIRC. Maybe I forgot to press the STEP key.

Tx,
Dave

Bump ?!?

I verified that I was pressing the keys per the manual.

i suggest that you may have a try as follows:
status:monitor
step----the Nf the step you want----write----step

Never Mind.

It can't be in RUN mode to read out the program.

It can't be in Monitor mode.

Pressing Write is BAD.
