Mitsibushi F2 series function codes

[whesco]

Can any body tell me where I can get a list of the function codes used in Medoc programing?
I am trying to decipher a program that I need to modify but it seems to contain F670 functions that are not listed in my manual such as "K157" & "K5"
Help please

Function 670 seems a bit high are you sure it is a function.

The F2 is an old plc and I dont know where my manual for it is.

The K157 and K5 are decimal numbers, maybe timer or counter settings or numbers in data registers

Can you post the parts you dont understand?

The function F670 K5 is a timer setting, where if the timing value in the program becomes 0, the value stored in RAM becomes valid. It overrules the value of the setting in the program.

F670 K157 is a zone compare instruction. The instruction has several explainations depending off the program it is used in.
See the programming manual "Enhanced F2 series" for a brighter explanation, including some examples.

Thanks for your information - I have obtained a copy of the enhanced F2 Manual which has answered most of my questions.
There are still two F670 commands that I can't find in the manual
These are F670 K181 & F670 K513 which are at the start of the program both fed through a NC contact on the M70 relay - any ideas?

You're right about the commands F670 K181 and F670 K513 ther are not mentioned in the manual. I can only tell you that M70 is a run bit. Witch is on during run.

Maby you can try to contact you're mitsubishi dealer about those commands.

I tried a PLC change in Melsec Medoc for it, but medoc didn't understand the command either.

Do you have a soft copy off the manual, or a hard copy?
