Allen Bradley + Prosoft Tag ReadOnly

[ptcjoe27]

Hi All,

Good day.

Just want to know if you all have an idea on how to convert a Bit address (Local1:I.Ch0Data) from Allen Bradley to Modbus Address 10**** using Prosoft MNETC.

Thank you in advance.

Sorry newbie here..

Thank,
Joe

Welcome to the PLCTalk forum community !

Do you already have this module running in your system, or are you setting it up for the first time ?

First, the tag you describe is not a Boolean "bit" format; "Local1:I.Ch0Data" it must be an integer or floating point value.

Please explain specifically what kind of module that data comes from, and folks can help you understand its data type and meaning.

Prosoft MNETx modules have an internal "database" that is a simple flat one-dimensional table of integers. Users configure the module to "map" sections of that database to ranges of Modbus addresses.

Your first task is to determine which section of the database is represented as Modbus "Input" registers (the ones that are denoted with 1xxxxx).

The Prosoft example code and user manuals are really pretty good.

Hi Ken Roach,

Thank you very much for your reply.

Sorry for the wrong choice of word. It is "Boolean" and not "Bit".

The prosoft will be installed next month. I just want to prepare it today

I also follow the instruction manual of prosoft but the example is only a float/real.

Anyway. Thank you very much again for your reply Ken.
