Page 8: Overview
Note: Please refer to separate User Manuals for the WI-I/O 9-1,2,3,4 products. The WI-I/O 9-K product will be referred to as the “WI-I/O K” for the rest of this manual to clearly delineate it from the other WI-I/O 9-1,2,3,4 products. -
Page 9: Power Supply
It is suitable for use in utility industries such as electricity, water and gas, as well as a cost effective solution for short range applications in factories and industrial plants. To extend radio range, WI-I/O 9-x modules can be used as repeaters. Up to five repeaters can Manual v1.9 Page 9 WI-I/O 9-K... -
Page 10: Configuration
WI-I/O 9-K be configured for each input-to-output link. The configuration is done at the WI-I/O K module where the input signal is - no additional configuration is required at the WI-I/O 9-x modules. The transmitted radio message will include the address of repeater modules - modules with these addresses will re-transmit the messages. -
Page 11: Operation
The paralysis time may be set from zero to 127.5 seconds for each input. For example, assume the paralysis time on an input is 30 seconds. If the input changes, then the WI-I/O K will transmit a message, however it will not transmit another message for this Manual v1.9 Page 11 WI-I/O 9-K... -
Page 12: Inputs
WI-I/O 9-K input during the next 30 seconds, regardless of changes to the input signal. Note that paralysis time does not stop re-transmissions of each message - if the WI-I/O K is configured to transmit each message three times, then paralysis will not stop this. - Page 13 For pulse rates higher than 10 Hz, the “Fast Pulsed Inputs” option should be selected. This increases power consumption of the module significantly and this needs to be considered if using a battery power supply. Manual v1.9 Page 13 WI-I/O 9-K...
-
Page 14: Shaft Encoder Inputs
WI-I/O 9-K Overview: • Pulse inputs are counted as 2 x 16 bit registers. • Pulse count is transmitted when the count has increased by the sensitivity amount since the last transmission. • Update message if the input value has not been transmitted within the update time (10 seconds - 7 days). -
Page 15: Analog Inputs
Note that continuous analog loop operation will result in a short battery life if a battery supply is used. A solar panel and battery supply is suitable. If an externally powered analog signal is connected, then the same measurement process as described above occurs . Manual v1.9 Page 15 WI-I/O 9-K... - Page 16 WI-I/O 9-K When the WI-I/O K takes a measurement, it will transmit the analog value if the value has changed by more than the pre-configured sensitivity since the last transmission. The sensitivity can be configured from 0.1% to 75% with a default value of 3%. If the change in the signal since the last transmitted value is less than the sensitivity, then the WI-I/O K will not transmit the analog value.

The unit will restart when the supply voltage has increased to the configured high SP value. 2.4.10 Communications Failure The WI-I/O K cannot provide an indication that its transmitted messages have not been received successfully. Manual v1.9 Page 17 WI-I/O 9-K... -
Page 18: How To Design A Remote Monitoring System
WI-I/O 9-K This indication is however available at the receiving WI-I/O 9-x by using the WI-I/O 9-x Output Reset on Comms Fail function. To use this function, map an input that is not being used on the WI-I/O K to a spare output on the WI-I/O 9-x. The unused input can be an internal input such as the Low Voltage status or Setpoint status, or even the analog input as this can also be mapped to a digital output. -

WI-I/O 9-K 5 DIAGNOSTICS AND TESTING 5.1 System Problems Most problems relate to incorrect configuration, or radio path problems. Before installing the WI-I/O K module, "bench-test" its operation with the receiving WI-I/O 9-x module alongside. If the WI-I/O K does not work properly in this test, it will not work properly installed. If problems are found, check the configuration. -
