Hi Team,

I am trying to program an Andon display with S7 412-2PN CPU using RS-485 interface. Now I'm having some doubts that:

1. What cable should I use for wiring the CPU-MPI port with the Andon!

2. What will be the pin configuration diagram of that connector!

Will be waiting for your help.

Hi OMKRIS2017,

1. U will need to use dedicated CP for point to point interface e.g. CP440. MPI port can't be used for this purpose.

2. The pin out diagram is provided in the respective manual.

Hello Sachin,

Thanks for your response. Now I want to know that if I want to use CP440 or CP441 then will there be a requirement of any extra license for data sharing between CPU & Andon display?

Also does this same workout is possible if I use a Profinet Gateway instead of CP441 for data communication?

Hello,

Cameback after a long time. Now I've used Anybus Profinet to RS-485 converter for communication between the S7 412-2 PN PLC & ANDON Display. The Anybus device I've successfully installed the GSD & configured it in the TIA V1 SP1 software in which I'm doing the logic.

Now one strange problem I'm facing. The issue is that whenever I'm assigning Input/Output address length like 8bytes or 32 bytes or 27 bytes the Anybus device is showing fault, it's 02 no LED get's continuously blinking RED. But whenever I'm deleting the address range then the deice LED is glowing GREEN.

I'm confused that why such peculiar thing is happening. I'm attaching the Anybus device data specs for reference, it's very simple but can't understand that why in TIA such issue is happening.

Waiting for response. Is there any other method of configuring the Anybus card or some other reasons are there for this issue. Also I forgot to mention that no data is getting exchanged in the address I've assigned in the Anybus IO's.
