Wilo-Control DigiCon
The DigiCon interface converter converts
the PLR interface (point-to-point inter-
face) into an RS 485 serial digital interface
with bus capability. The software protocol
is PLR. The protocol is described in detail
on the attached CD and needs to be imple-
mented accordingly.
Pumps that can be connected:
• 4 pumps (single or double)
Tab. 4
Pump types that can be connected: Cf.: Tab. 2.
NOTE:
• Double pumps must always be equipped with integrated dual pump
management.
• In the case of double pumps, the PLR interface of the master is connected to the
interface converter.
• If integrated dual pump management is not used for double pumps, both drives
must be treated as two separate single pumps.
• Control functions relate to the double pump as a complete unit.
