8.3.2 Wireless Modbus Slave Mode
Wireless MODBUS allows one or many GDA-1600s to function as wireless Modbus
slaves by connecting their RS-485 Modbus slave
The entire GDA-1600 Modbus database, including registers and supported Function
Codes, is documented in section 5.1.
ports to a radio modem. These wireless
networks require a Modbus master such as a DCS, HMI or another GDA-1600 also
equipped with a radio modem. One transceiver must be designated as Server and all
others as Clients. No special configuration is required by the master or slave since this is
a standard Modbus network. However, radios must have the same
Hop Channel and
System ID settings to communicate. Radio modules may only be configured when
connected to the GDA-1600’s master port. If it is necessary to modify
Hop Channel
and
System ID settings, the radio module may be temporarily connected to the GDA-
1600’s master port for configuration then moved back to the slave port for operation.

mixed between the GDA-1600’s sixteen channels so it is also possible to accept wired
signals from analog input option PCBs described in section 4.2.
