Wire the outputs in accordance with
Wiring Diagram 6 - Modbus to Profinet
. In addition,
useful for wiring to the BIOGAS 3000 Modbus outputs.
For optimum performance, it is recommended that screened twisted pair cable
be used.
Note: For cable conductor sizes and cable insulation requirements, please
refer to section
Cable Conductor Sizes and Insulation Requirements
Note: If the distance between the BIOGAS 3000 and the Profinet
converter module is greater than 200m, it may be necessary to add a
termination resistor at the Profinet end to ensure noise-free
communications. In this case, place a 200ohms (0.25W) resistor across
the two data line terminals pins one and two on the Furse ESP SL06/I.
Note: For further information please contact our technical support team

When wiring the Modbus connections the twisted pairs must be as follows:
Terminal Colour
Wiring Information
Pair
Orange
Signal A (RS485) ‘+’
Pair one
Blue
Signal B (RS485) ‘-‘
White
Logic Ground (0V) ‘LG’
Pair two
must not exceed 83.3mA. Operating outside of this
range will invalidate the ATEX/IECEx certification.
