Are ATV930 compatible with STBNIP2212?

[RvV_TechnoServe]

I have a client with approximately 47 ATV71 drives in their plant.

These are connected to STBNIP2212 based islands.

The client is on a quest to replace the drives with ATV930 drives over a period of time.

They will eventually replace their STBNIP2212 with STBNIP2311 NIC's, but don't necessarily want to do that right now.

Can the STBNIP2212 be used to communicate to ATV930 drives?

If so, will it be possible while some of the drives on the NIC is still ATV71's?

Hi RvV_TechnoServe,

Could do with a little more information here ... as the STBNIP2212 Advantys NIMs are single port, can you please clarify how the current ATV71's are connected to them? Is it just analogue and digital I/O or is there some other way they are connected?

hi,

The answer to your question depends on the communication protocol in use and the application program implemented in the master controller. If the master is simply issuing speed references via the FC6 Modbus command, it is very likely that no issues will arise. However, if function blocks have been used, or if an I/O profile or any other specific configuration was implemented with the ATV71, one cannot assume that replacing it with an ATV930 will work seamlessly. While the two products are functional equivalents, the actual outcome will ultimately depend on the program logic and the method of integration

Hi Ismaelozinan,  

I am awaiting the M340 PLC program from the client to check the control function in the program.

Hi DuMalt,

There are 7 NIMs with varying I/O configs and different quantities (between 2 and 12) of ATV71s connected via XBE2100's, similar to the following:

All NIMs are configured differently, their I/O cards and quantities differ.

The cards used are as follows:

• DDI3725
• DDO3705
• AVI 0300
• AVO 1255
• EHC 3020
• ART 0200

Just to clarify - this is my first NIM Rodeo, so any assistance will be most welcome.

I can add a little contribution here:
After seeing the architecture, it was a common usage in the past to have STB range as a Canopen gateway for the following reason:
All VFDs in that time had Canopen embedded and, for having Modbus TCP, a additional card was required (extra costs).
In this case, it was just a matter to include 1 extra module (STBXBE2100) into the island and you could attach several Canopen slaves.
Nowadays, ATV930 have by default Modbus TCP and Ethernet/IP and you can simply add directly to the Ethernet side and not into the Canopen anymore.
If M340 + NOE module are the PLC, it quite simple to add a new device into the IO scanning for Modbus TCP.
