DAQFactory Configuration and Operation. 
 
  DAQFactory is a very powerful process control, monitoring and acquisition program available 
form Azeotech  (http://www.azeotech.com
). Running on a PC DAQFactory comes with built support 
for connecting to an RFScada device, so a complete application may be built very quickly without 
requiring complex details...

numbers in DAQFactory. When DAQFactory accesses a Device number other than 0 it is actually 
reading or writing to the physical RFScada Unit 0 (master) which is connected to the PC’s serial port; 
RFScada Unit 0 will then read or write data via radio to the requested RFScada unit. All of this 
reading, writing, storing and forwarding occurs inside the...

1   Some, but not all RFScada ‘slave’ units are responding to radio signals from 
the RFScada ‘master’ unit. 
2  None of the RFScada ‘slave’ units are responding to radio signals from the 
RFScada ‘master’ unit. 
 
If the radio network status is 1 it is possible to find out which units are not operating correctly, refer to 
the RFScada individual network...

units ID, 0 to 31; I/O Type: Dig Out; Channel: the units channel, 1 to 8. Write to the channel either a 1 
(relay active, normally open contacts closed) or 0 (relay inactive, normally open contacts open).  
 
Cautions when Writing to Outputs. The RFScada Units are designed for operation in many diverse 
applications, and may control devices such as motors...

Modbus Configuration, Control and Monitoring. 
 
When the RFScada units are shipped they will already be configured for the final application, 
and no further programming, configuration or adjustments are required. Each unit stores its own 
settings inside non volatile memory where they will remain until the unit is reconfigured. Connection to 
power is...

Signal Connection 
Ground  J16 Pin 3

B  (transmit & receive)  J16 Pin 2 
 
RS-485 networks often use a terminator resistor, value 120 
Ohm at either end of a transmission line. The RFScada units do not 
have this resistor on the main board, to allow it to be connected at any 
point. If the RFScada unit is the last...

normal circumstances Modbus access and control would be at unit 0, allowing full access to the 
system. Access at slaves is primarily intended for testing, to change local settings, such as a timeout 
value, or to override and ‘force’ local inputs via Modbus. In the following descriptions it is assumed 
that the Modbus connection is made to the master...

source unit ID for the analog signal, and the least significant 3 bits are the analog input channel. So, 
in this case if the lower byte was 11011010 Binary (218 decimal or 0xDA hex) analog output 7 in unit 
10 would be driven by analog input 3 on unit 27. If the upper byte was 01100111 Binary (103 decimal 
or 0x67 hex) analog output 8 in unit 10 would be...
