RTU features (not for TRM-810)
3.5.1
Setup
The "Setup" menu configures the basic features of the
integrated inputs and outputs.
3.5.1.1
RTU information
This is a summary about the physically available inputs, outputs and counter inputs of
the RTU-810. This information includes connected expansion modules.
3.5.1.2
RTU options
Process ZZTR
telegrams as
MODBUS
To access RTU-810 radio networks from a SCADA master, a TRM-810 or
RTU-810 with the serial master mode ZZTR/ZZTRM can be used.
If the RTU-810 receives a ZZTR telegram, it will check if this is a
MODBUS-RTU datagram when this option is turned on. If the MODBUS
address is matching the RTU-810's MODBUS address, it'll answer the data.
RTU MODBUS
address
This is the MODBUS address of the RTU-810. This setting is the same as
configured in "3.3.5 Access".
Note that the MODBUS address and the radio slave address are different
things. Although it's recommended to keep them the same, they can be
configured different.
In this case, the radio telegram must be sent to the radio slave address of the
RTU-810, and the embedded MODBUS-RTU-telegram must be addressed
to the MODBUS address of the RTU-810.
