SerialEncDataB Acc84E bits

[dhidas]

I'd like to have a shorthand way to look at the bits in SerialEncDataB, for example looking at the CRC bit etc.  I thought something like this might work, but it doesn't seem to.  Is there a good way to do this without having to do all of the bit shifting in a PLC?

 

#define LENC1CRC Acc84E[0].Chan[0].SerialEncDataB.22.1

You could put your data into a Watch Window....and then, in the response column, choose  BINARY format.

Wouldn't that give you what you desire?

I'm looking to use it in a PLC (script language)

A user shared memory address could be used to hold the value of Acc84E[0].Chan[0].SerialEncDataB, and then individual bits in the user shared memory addresses could be accessed.

For example:

u.user:$3000 = Acc84E[0].Chan[0].SerialEncDataB

ptr LENC1CRC->u.user:$3000.4.1 // for reading bit 4

See under the headings User Shared Memory Buffer Variables and M-Variable Access  in the Power PMAC Users manual for details.

Thanks, this looks to be what I was after!

(small correction is a missing : after u.user): ptr LENC1CRC->u.user:$3000.4.1

Thanks for the correction.  Note that I went back and edited to make the correction.
