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 s ave port for operation The entire GDA 1600 Modbus database including registers and supported Function Codes is documented in section 5 1 8 4 Wireless Modbus Master Mode GDA 1600 applications as a Wireless Modbus master are similar to the Wireless Receiver mode described in section 8 3 on page 47 and wiring to the radio modem is identical The radio setup menus described in section 8 2 may also be used for configuring hop channel and system ID settings The difference is each channel s INPUT DATA FROM menu must be configured with the correct MODBUS values to match the slave device instead of Wireless RF900 Wired and wireless inputs may be 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 This is a popular application when the Modbus slave is another remote GDA 1600 or our GDA 400 controller available with built in rad
