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
