Title: create a "list of registers" to use with polling master blocks MRX/MWX
Post by: Pat Cooley on March 13, 2015, 11:53:54 AM

I am trying to create a way to use a list of registers with values to cycle through using indirect addressing in the fields of the MRX and MWX blocks.

i do it currently in Control Microsystems  with a counter value cycling the value.  I am trying to do the same thing in the Do-more. I would appreciate any help i can get with this.  you can e-mail me or call me at 501-539-2563

thank you

MRX:
From Modbus Offset Address: V[V0]

Now you can store your list of registers starting at V10-20 etc. And as you increment V0 from 10 to 20 it will read each of those values.
