Dear Experts,

i have a starnge problem regarding my system which consist of

-cpu 1214 dc-dc
-profibus signal module
-micromaster drive 440 with profibus adapter

the problem is the communication between CPU and Drive is faulty
the led on the Profibus adapter is orange

the micromaster drive PN is 6se6400-2cu13-zaa1
the profibus adapter PN is 6SE6400-1PB00-0AA0

I checked all parameters and all setting i reviewed all programs and examples in the fourms
still no communication

im using step7 basic v 10.5
 

strange note  i connect micromaster 440 with the same parameters to cpu 315 and the led on Profibus adapter is green just for testing

Onther thing how i know how many PKW and PZD for these drive?

Hello Muhammad;
First, about that flashing LED on your drive:

The Profibus unit fitted to the MM4 shows a red or orange light. What can cause this?


Next, here is a little help understanding Profibus-DP cyclic comms between a Profibus master and the MM4, and a few sample programs (for a S7-300), and  what parameters must be setup on a MM4 drive to ensure correct Profibus-DP exchanges:

Operating Instructions: MICROMASTER PROFIBUS Optional Board 
Notice the description of PPOx profiles (which you select when you configure the drive in the Profibus configuration; this determines the amount of PKW and PZD words that will be used for Profibus exchanges).

Are there program examples for the Instruction Manual of the MICROMASTER PROFIBUS option module?

What is important when setting up an MM4 with a Profibus module?


And finally a few threads from the forum discussing S7-1200 communications with a Micromaster drive:

Hope this helps,
Daniel Chartier
