[involves Allen Bradley L32E Control Logix PLC and Unitronics V350 OPLC via Serial Port: DF1 Communication]

thanks, this seem to make sense. I will perform the test today. i will post on progress.

[involves Allen Bradley L32E Control Logix PLC and Unitronics V350 OPLC via Serial Port: DF1 Communication]

Hello,

My name is Rhulani Marhanele from NCP Yeast and I am busy with the project which involves Allen Bradley L32E Control Logix PLC and Unitronics V350 OPLC.

I am using DF1 Communication protocol – via Serial Port, guided by the attached document (find attachment) and the Visilogic V9.3.1 Help file.

Software: For V350 = Visilogic V9.3.1

For L32E = RSLogix 5000

I’ve got in to a point where I can communicate between these two PLCs and I can send/Receive the following data types:

Integers: MI and XI

Floats: MF

I am currently struggling to Send/Receive the following data types:

Booleans: MB and XB

Timers

Counters

May you please assist me to configure the PLCs to achieve the transfer for the rest of the data types (Bool, Counter and Timer).

I will appreciate your assistance.

Thanks.UNITRONICS V130 V350 V570 DF 1 COMMUNICATION (3).doc
