R085, R086 Converter P-Bus / Modbus RS485

R085, R086

R085 and R086 are microprocessor-controlled converters of Landis & Gyr P-Bus for I/O modules Landis & Gyr PTM..., PTK... to Modbus RTU over RS485. The converters provide galvanical separation of both interfaces and the power part, and they are able to supply 32 or 64 BE (P-Bus load units) respectively.

Datasheet

R085 and R086 are microprocessor-controlled converters of Landis & Gyr P-Bus for I/O modules Landis & Gyr PTM..., PTK... to Modbus RTU over RS485. The converters provide galvanical separation of both interfaces and the power part, and they are able to supply 32 or 64 BE (P-Bus load units) respectively.

  • integration of Landis & Gyr I/O modules into a SoftPLC or 3rd party environment – reconstruction and refurbishment of old plants using Landis & Gyr PRU.., PRV.., and RWP80 controllers.

The converter links the I/O modules of total load of up to 64 BE to Domat MiniPLC, Domat IPLC500, IPLC510, IPCB.1, IPCT.1, to a SoftPLC runtime or to any other client capable of Modbus RTU communication. 

After powering on, the converter continuously scans the P-Bus and searches for the connected I/O modules which updates the internal I/O list. Using special commands (over domat.exe or according to the Modbus table) it is possible to save the actual configuration of the P-Bus (addresses and types of the I/O modules) into the memory of the converter, which speeds up the P-Bus communication. This is recommended especially at higher Modbus baudrates.
