Notes for Installation and Setting up
RFM 12/ RFM 32/ RFM 62 with Leuze multiNet at MA 21 100.2
Installation
For RS 485 networks it is important to avoid A-/B-wire interchanges. A separat
network ground line is recommended, too. The shield should be connected
only on one side. At the last slave in line, the network has to be terminated by a
220
Ω
Ω
Ω
Ω
resistor. After mounting the RFM and MA, turn the address switch of
each MA 21 100.2 to the dedicated address and set DIP-switch 1 to ON
(„Transparent-Mode“), for network operation set DIP-switch 3 („Service“) to
OFF. At the multiNet master (MA 31) the total number of slaves has to be set.
Before switching on the power supply please check the wiring.
Setting Up
When the firmware is started, the MA 21 and the RFM give a ready sign on the
network with „XXs“ (XX is the slave address). The parameter setting can be
done either with each device via Service interface or via multiNet master and
the slave address in front of the command („01V“). If all slaves should be set to
the same parameters, you can set a“00B“ in front of the parameter string and
send it to the master device. After the setting of the parameter, please make
sure that all DIP switches are set to „HOST„ („operation“).
For more details concerning the MA 21 please see the technical manual of the
MA 21.
