RFM 12/ RFM 32/ RFM 62 on PROFIBUS via MA 42 DP-k
After mounting of the RFM and the MA, turn the address switch of each MA 42
to the dedicated address. By the integration of the GSD-file into the PROFIBUS
master, all configuration data of the MA 42 is usable for the PLC. The
configuration of the RFM is done very easy via service interface of the MA42
and the RF-config tool. To do so please set all 3 DIP–switches to „Service"or
"RS 232". When the configuration is finished set back the DIP-switches
to„Betrieb" or „PROFIBUS"(operation).
The complete configuration telegram could be send directly from the PLC to
the RFM (like a Command telegram). The structure and the description of the
parameters are in the "telegram and command structure" file.
If communicating to the RFM device via PROFIBUS please note that each
character is handled as ASCII-character and must be transfered into
hexadecimal . With commands or telegrams longer than 6 Byte (including pre-
and postfix), each part of the telegram has to be stored in the memory of the
MA 42 (look for correct sequence). If the telegram/ command is complete in the
memory of the MA 42, transfer the whole content with the bit „SFB" to the
RFM. After the transfer, the memory of MA 42 has to be deleted.
For more details concerning the MA 42 please see the technical manual
MA 40/ MA 41/MA 42 DP-k
RFM 12/ RFM 32/ RFM 62 on PROFIBUS via MA 204i
After mounting of the RFM and the MA, turn the address switch of each MA
204i to the dedicated address. By the integration of the GSD-file into the
PROFIBUS master, all configuration data of the MA 204i is usable for the PLC.
The configuration of the RFM is done very easy via service interface of the
MA204i and the RF-config tool. To do so please set all DIP–switches to
„„Service"and"DEV ".When the configuration is finished set back the DIP-
switches to„RUN"(operation).
The complete configuration telegram could be send directly from the PLC to
the RFM (like a Command telegram). The structure and the description of the
parameters are in the "telegram and command structure" file.
If communicating to the RFM device via PROFIBUS please note that each
character is handled as ASCII-character and must be transfered into
hexadecimal . With very long commands or telegrams, each part of the
telegram has to be stored in the memory of the MA 204i in the collecting mode
(look for correct sequence). If the telegram/ command is complete in the
memory of the MA 204i, transfer the whole content with the bit „SFB" to the
RFM. For more details concerning the MA 204i please see the technical manual
