Here's an example using FC16 from the IEC library. FC16 creates a string. If you just want the chars then pick them out from the string.

I used 12345 in the example I posted and the correct values are being read from the string, note that '1' = 31(hex)

What???

A local variable is a scratch flag!! with the added convenience of the ability to name what its function is.

I have never come across any company that specifies that you cannot use them, it makes no sense whatsoever.

Smacks of someone with no knowledge making up rules.

No Local Variables?


Sounds to me like someone once had a bad experience with an un-initialised temp and has decreed that they are evil.

Yes, declare a string variable (say sMyString in DBx) then enter DBx.sMystring as the RET_VAL from FC16
