Hello,

JECV1097

Please would you give me more details about your configuration? I've managed to establish communication between a s7-1500 and 16 Danfoss FC 302 with Eth/IP Option. However, the delay is too much, up to10 seconds in some cases. I am trying to change my cyclic OB Time (10 ms) or the RPI (I've tried with 10, 30, 50 ms) of the drivers without any important change. This delay activates alarms and warnings in the drivers. I am looking for some advice.

 it is quite expensive to handle 16 drives with this kind of communication. Question is, how you did your system of communication. 10s timeout is simply not clear to me but it maybe points to cyclical poll of data each device after another one with one comm block. Did you something similar as Example from Daniel's post shows? That example shows 2 devices attached to network.
