1 Liquid Cooling Unit[edit | edit source]
1.1 VEO Heat Exchanger[edit | edit source]
Since the 1830 DAP the Heat exchange units will be delivered with a LOGO. For Parameters and configuration please look inside the manuals.

1.1.2 Communication[edit | edit source]
Vacon OptE9: 172.31.30.20
Logo: 172.31.30.21
Logo TDE (Touchpanel): 172.31.30.25
Set the subnet mask and the gateway exactly like other devices you have on this profinet, e.g. 255.255.0.0 and Gateway 172.31.0.1.
Otherwise you will not be able to ping the two devices from service net.
Explanation:
Communication is using SFB14 GET and SFB 15 PUT to communicate directly with a remote PLC (== LOGO).
The local ID for the S7 connection must not be changed without also changing the parameters for the GET/PUT code in SCL. So do not touch or change.
NetPro must be downloaded ! File:VaconLogoNetPro.PNG
