AB Basic Module 1746-BAS

I need some help with AB Basic Module 1746-BAS. What is the designation of the bits of the first word of the modules input and output tables. The manuals do not list then. (or I can not find them). I only found the following.

I:e.0/13 = batter status
I:e.0/15 = run mode status

I am trying to trouble shoot someone else’s program. The seems to be a timing issue with slc500 and the device the Basic module is communicating with. I think some of the bits from the first word do not do what they are labels as.

First time using this Module Boy is it fun

Do you mean the serial port IO buffers?

I think you need to access those through Mfile transfers. It's been a while, though...

akreel I do not mean the M files I understand how they work. The M file are mapped to Basic module buffer words 100 – 163.

There are 8 words of I/O, 8 inputs and 8 outputs. These word are buffers 200 to 207 in the Basic Module.

The first word of each input and output have dedicated bit meanings. These are the designations I am looking for.

I think I see what you mean, and I understand your frustration with the documentation.

I haven't needed to access those words. I looked into it once, but never spent any time on it. Can you have your basic program write a value into one of those words and then look it up in the I/O table while you're online?
