SLC500 - Adding Message Data Type

[Ones_Zeros]

Hello
I was trying to add a "Message" data file in a SLC500 PLC controller.
I'm not seeing the Message as a "type" to select.

How do I add the message as a option to choose in the type box from with the "create data file" dialog box?


thanks,

MG datatypes are only for the MicroLogix controllers.

In any SLC-500, use a block of Integer (N) data of the appropriate size. DF1 or DH485 or DH+ messages use 14 words, and Ethernet messages use 51 words.

So I would use these instructions? (DF1 or DH485 or DH+)
I’ll do some research on how to use them to message
between SLC500.

I’m not sure how to use them

Could you possibly provide an example?

Thanks for the explanation

I appreciate it

Which exact models of controllers are you using ? What sort of network connections do you have ?

What's your goal for messaging between controllers ?

Thanks for helping.

- The model of both PLC controllers is 1747-L552 (5/05)
- The network connection between these two PLC’s is Ethernet CAT5 connection.
- My end goal is to Message over several (N) Integers from PLC A to PLC B.
I will be using these Integers from PLC A to turn on a Output in PLC B


Thanks Again
