Description

This is an addendum to the Spread Spectrum Wireless Data Transceiver User Manual. It covers details applicable specifically to using the FreeWave FGRIO Master and Slave modems. Please use this addendum in conjunction with the User Manual.

The FreeWave Technologies FGRIO System provides outstanding performance and versatility in wireless transmission of process-control signals. FGRIO offers “transparent” acquisition, transport and reconstruction of analog, digital and power signals, eliminating the need for associated buried wiring. The RTU requires no altered programming. The FGRIO is Class 1 Div 2 approved and is lower-cost and provides better signal integrity than vulnerable wiring.

The FGRIO System is based upon wireless RF Technologies. RF is subject to interference and communication interruptions. It should not be expected, therefore, to provide 100% communication, 100% of the time. The FGRIO System should not be used without proper provisions to ensure safety upon loss of radio communications.

Glossary FGRIO Master– FreeWave wireless radio transceiver that operates as a Master for up to 4

FGRIO or FGR2-IO Slaves, and can operate as a Slave in a point to multipoint network. The FGRIO Master can receive over air a total of 4 analog input signals and 4 digital input signals from up to 4 FGRIO or FGR2-IO Slaves. It can also transmit up to 4 digital output signals over air to the FGRIO or FGR2-IO Slaves. The FGRIO Master does not operate as a Slave/ Repeater in the SCADA system.

FGRIO Slave – FreeWave wireless radio transceiver that accepts up to a total of 4 input signals from sensors, then transmits these signals over air to the FGRIO Master. Two of the 4 available input signals can only be transmitted as analog signals and are labeled as Analog Input 1 and Analog Input 2 on the Slave’s terminal block. The other two input signals may be either analog or digital inputs, depending on the user’s needs. The FGRIO Slave can also receive over air 2 digital output signals and a sensor power control signal from the FGRIO Master.

FGR2-IO Slave – New generation FreeWave wireless radio transceiver that accepts up to a total of 4 input signals from sensors, then transmits these signals over air to the FGRIO Master. Two of the available 4 input signals can only be transmitted as analog signals and are labeled as Analog Input 1 and Analog Input 2 on the Slave’s terminal block. The other two input signals may be either analog or digital inputs, depending on the user’s needs. The FGR2-IO Slave can also receive over air 2 digital output signals and a sensor power control signal from the FGRIO Master. The FGR2-IO has a line-of-sight range of 60 miles, compared to the 2 mile line-ofsight range of the FGRIO Slave.

A note about terminology: The phrase ‘FGRIO System’, when used in this manual, will refer to any system that uses an FGRIO Master in conjunction with either FGRIO or FGR2-IO Slaves. IO Slave will refer to either an FGRIO Slave or an FGR2-IO Slave.

Glossary (cont.) Analog Circuit– An electronic circuit that operates with currents and voltages that vary continu-

ously with time and have no abrupt transitions between levels. Temperatures, pressures, or flow rates are all represented by analog circuits.

Digital Circuit– An electronic circuit that functions as though currents or voltages exist only at one of a set of discrete levels, all transitions between levels being ignored. The states of a digital circuit are often referred to as on or off, high or low.

VSNS- This is screw terminal # 7 on the IO Slave. This is an output used to power sensors/ transmitters. The maximum output voltage of this terminal is 20VDC for the FGRIO-S and 30VDC for the FGR2-IOS-C-U and FGR2-IOS-CE-U

(9) FGRIO Setup (cont.)

(0) FGRIO – Must be set to 1 to enable I/O functions. (1) to (8) – To map the FGRIO Master outputs to the correct IO Slave inputs, use the following steps:

1) Select which IO Slave you are mapping to the FGRIO Master. Note the Master’s Call Book Entry # that lists this IO Slave’s serial number.

2) Next, determine which analog or digital input from the IO Slave radio you wish to map to the FGRIO Master. This could be Analog Input(AI)#1, AI#2, AI#3, AI#4, or Digital Input(DI)#1, or DI#2, depending on which sensor(s) the Slave will be connected to.

3) Using the following table, find the intersection between the Master’s Call Book Entry # (found in step 1) and the selected input from the Slave (found in step 2). Note the number listed at this intersection.

4) Go to Menu 9, FGRIO Setup (Figure 7). Select which Master’s output you would like to “connect” to the input from the Slave. At the flashing curser, enter the number to the left of the selected output. Next enter the number found in step 3. This number should be displayed to the right of the selected output.

EXAMPLE To map Analog Output 1 of the FGRIO Master to Analog Input 2 of the IO Slave (serial # 930-

0004), entry (5) in the FGRIO Setup menu will have a value of 2. This is calculated by first checking the Call Book entry # of IO Slave #930-0004 (See Figure 9, next page). The entry # is

0. Next, go to the table above, find call book entry # 0, then go to the column for IO Slave Analog Input #2. The value listed is 2. A 2 will be entered for Analog Output #1 of the FGRIO Master.

(4) RF Data Rate– The RF Data Rate must be set to 3 when using the FGRIO System. This is for applications that are stand alone or when integrated into an existing FGR network. (8) Retry Timeout– By lowering the Retry Timeout, the inactive link time between the

FGRIO Master and IO Slave can be reduced when going from autonomous mode to connecting back to the FGR Network. If the Network Master goes down, the FGRIO Master and Slave will continue to operate in autonomous mode. When the Network Master comes back up, the FGRIO Master will break the link with the IO Slave to reestablish a link with the Network Master. Once the FGRIO Master is linked to the Network Master, then the IO Slave will be able to link back to the FGRIO Master. With a lower Retry Timeout setting, it will take less time for the IO Slave to link to the FGRIO Maser.

(5) MultiPoint Parameters- (0) Number Repeaters- This setting must be set to 1 for all FGR and IO radios in the

Network.

(6) Network ID– In addition to entering the FGRIO Master’s serial number in the Call Book, the Network ID being used for the Network must be set from 1-4095 (Do NOT use

255). Use the same Network ID for the IO Slave as was used for the FGRIO Master. Programming both the Call Book and Network ID settings is unique to the FGRIO System and must be done for both integrated and stand alone applications.

RF Data Rate - The RF Data Rate must be set to “Normal” (3) when using the FGRIO System. This is for applications that are stand alone or when integrated into an existing FGR network.

Retry Timeout– By lowering the Retry Timeout, the inactive link time between the FGRIO Master and IO Slave can be reduced when going from autonomous mode to connecting back to the FGR Network. If the Network Master goes down, the IO Master and Slave will continue to operate in autonomous mode. When the Network Master comes back up, the FRGIO Master will break the link with the IO Slave to reestablish a link with the Network Master. Once the FGRIO Master is linked to the Network Master, then the IO Slave will be able to link back to the FGRIO Master. With a lower Retry Timeout setting, it will take less time for the IO Slave to link to the FGRIO Master.

logs, or float to not load analog inputs.

Note: Both of the IO Slave Digital Outputs may be driven by the same FGRIO Master Input.

(3) 1-5 Volt Sensor, Analog Input 3 or Analog Input 4

With FGRIO-S firmware 2.65IO or FGR2-IOS firmware 9.7, and FGRIO-M firmware 2.65, the Digital Inputs (DIs) of the FGRIO-S or FGR2-IOS may be digitized to 10 bit resolution and mapped to Analog Outputs (AOs) on the FRGIO-M. This allows up to 4 analog transducers to be connected to a single remote FGRIO-S or FGR2-IOS radio.

A. Signal Levels and Accuracy.

The existing AIs at screw terminal #8 and screw terminal #10 are usable with .1V to 5.625V input voltages (compatible with most 1-5V and 4-20mA transmitters) and load the input with about 100Kohm to GND. They also offer accuracy of +/-.1% with 16 bit resolution and are therefore recommended for the most critical variables in a system.

In comparison, the new AIs formed from the DIs at screw terminal #1 and screw terminal #2 are directly usable with signals only from .1V to 2.812V in wire replacement mode. Input loading can be selected as 10Kohm to GND or unloaded (>1Megohm). Accuracy is within +/-.25% and resolution is 10 bits. The next section describes methods to best apply inputs to them.

B. Signal Coupling for Analog Input 3 and Analog Input 4.

1) Input Resistor The IO Slave DIs have always provided an internal 10Kohm resistor pull-up to the radio’s 3.3V logic supply. With new firmware 2.65IO in the FGRIO-S, or 9.7 in the FGR2-IOS, the resistor can also be commanded (in the FGRIO Setup menu) to pull down to GND or “float” unconnected. As will be shown, these options are useful for connection of analog inputs.

2) Signal Level Reduction. As stated above, the DI does not have sufficient voltage range for direct connection to typical transducer outputs, so the input must be restricted. For signal replication, it is assumed the input signal level will be halved, and the measured value sent to the FGRIO-M doubled, to achieve an overall 1:1 signal reproduction.

3) VSNS Sensor Power The switched voltage source at screw terminal #7 is designed to drive only two 4-20mA transmitters to full scale. Voltage output (1-5V) transmitters usually consume less current and may allow up to 4 to be switched.

Below are two diagrams showing the connection of a 1-5V sensor to Analog Input 3: (Figures 23 and 24)

Sensor, Analog Input 3 or Analog Input 4, apply when using a 4-20 milliamp sensor. The

switched voltage source at screw terminal #7 is designed to drive only two 4-20mA transmitters to full scale. If a system will use more than two, the additional transmitters must be powered from a separate supply, such as directly from the battery or another DC supply.

On the next page are two diagrams showing the connection of a 4-20 milliamp sensor to Analog Input 3 (Figures 25 and 26):

Installation (cont.)

IO Slave (5) Digital Input

• Switch Output Wire is connected to Digital Input 1 screw terminal # 1 or Digital In-

put 2 screw terminal # 2 on the terminal block of the IO Slave.

• Switch Ground Wire is connected to Ground screw terminal # 3, 9 or 12 on the ter-

minal block of the IO Slave.

If the Switch Ground Wire is not returned to the IO Slave, the potential difference between the IO Slave Ground and the Dry Contact Closure (Switch) Ground should not exceed 1 Volt.

• In the case of a 3 wire digital transducer, set up similarly to the 1-5V analog sensor,

except with the signal wire connected to a Digital Input.

(6) Digital Output

• Digital Output is an open drain field effect transistor connected to Ground. It con-

nects to Ground when zero volts is connected to the controlling Master Digital Input.

• The current rating for Digital Output is 2 amps or less. The Digital Output will self-

protect if a current of more than 2 1/2 amps is drawn and automatically retry at .16 second intervals.

• If power on the Solenoid (end device) is not driven from the same power supply as

the IO Slave, that source must be equal to or less than the IO Slave power supply voltage. Within the IO Slave, a 3 amp rated Schottky Diode is connected from each Digital Output to the radio power supply terminal for clamping the Solenoid fly back current. If the relay supply voltage exceeded the radio supply voltage, then current would flow through that diode back to the radio, preventing coil current from shutting off and potentially causing an overvoltage condition.

Installation (cont.)

FGRIO Master (1) Rx, Tx, B+

• Receive, Transmit, and Power are available on screw terminals of the FGRIO

Master terminal block as well as the 10 pin header.

(2) Analog Output

• The Analog Output wire is connected from the Analog Output 1,2,3 or 4 screw ter-

minal on the FGRIO Master terminal block to the Analog Input of the RTU (destination device).

• Common Ground is required. It is recommended to run a Ground wire from an

FGRIO Master Ground screw terminal to Ground on the RTU.

NOTE: Analog Output is 1-5 V at low current, so any 4-20 mA current sensing resistor

on the RTU MUST BE REMOVED. If in doubt as to whether RTU-internal resistors are active, test the link with a full scale input.

(3) Digital Output

• The Digital Output wire is connected from the Digital Output 1,2,3 or 4 screw termi-

nal on the FGRIO Master terminal block to the Digital Input of the RTU (destination device).

• Common Ground is required. It is recommended to run a Ground wire from the

FGRIO Master Ground screw terminal to Ground on the RTU.

NOTE: The Digital Output actively drives Low (.4V) and High (4.0V). Remove any

RTU input pull-up resistor, if less than 10 K ohms. Verify that signal levels meet the RTU input requirements after connection to the RTU.

(4) Digital Input

• The RTU Digital Output Wire is connected to Digital Input 1,2,3 or 4 screw terminal

on the terminal block of the FGRIO Master. An internal 10Kohm pullup to +5V is provided.

• The RTU Ground Wire is connected to any of the Ground screw terminals on the

terminal block of the FGRIO Master. Some RTUs use isolated I/O and may require a ground connection for each input and output.

(5) Sensor Power

• To minimize power drain of the IO Slave Solar/Battery System, an input terminal

called Sensor Power is provided on the FGRIO Master terminal block. Sensor Power has an internal 10 Kohm pull-down to Ground.

• If the RTU provides a switched sensor power output, connect it to this terminal.

Verify that the level at Sensor Power falls to < 1.0 V when de-asserted to ensure the slaves will mirror. If not, connect additional pull-down resistance externally.

FGRIO Master (5) Sensor Power (cont.)

• The state of that sensor power will be mirrored at the IO Slave, powering the sensors

at the IO Slave on and off. It is necessary to change FGRIO Setup sub menu (A) to “1” (Gated).

NOTE: The sensor power terminal both activates sensor power at the controlled IO Slaves, and activates Analog Outputs at the FGRIO Master interface board, when in Sensor Power “Gated” mode.

(6) Link Alarms

• Link Alarm 1 is an alarm reflecting loss of communication on any path. A wire is

run from the Link Alarm 1 screw terminal to the Link Alarm screw terminal on the RTU.

• Link Alarm 2 (CMD Alarm) indicates that a Digital Output or Sensor Power com-

mand was not carried out due to an over-current fault. A wire is run from the Link Alarm 2 screw terminal to the Link Alarm screw terminal on the RTU.

NOTE: The terminal block of the FGRIO Master and Slave can accept a single wire up to 16 gauge. Smaller wire is required for 2 wires, or wire + resistor into the same screw terminal.

Frequently Asked Questions Q: Can IO be used with a 1 watt radio?

A: The FGRIO Master operates as a standard FGR 1 watt radio with a 60 mile line of sight

range. The FGRIO Slave functions as an FGR radio with a 2 mile line of sight range. The FGR2-IO Slave functions as an FGR radio with a 60 mile line of sight.

Q: Can the IO radios be repeated through our other radios to extend the range?

A: From the IO Slave to the FGRIO Master, repeaters cannot be used. From the FGRIO

Master to the rest of the existing network, repeaters can be used as they already are in existing FreeWave networks. The FGRIO Master will not function as a Slave/Repeater

Q: Can the FGRIO Master operate as Slave/Repeater in the overall network?

A: The FGRIO Master currently does not have the capability to operate as a Slave/Repeater. It

does function as the Master to the IO Slave, and as a Slave to the rest of the network.

Frequently Asked Questions Q: Can data be sent directly from the IO Slave to the Master of the FreeWave network?

A: No. The FGRIO system functions as wire replacement only. The IO Slave does not

have the capability of transmitting data directly to the Master of the network.

Q: What are the sizes of the FGRIO Master and Slave?

A: The board level IO Slave has the same footprint as the FGRO9 family. The board level IO

Slave dimensions are 127 mm (L) x 61 mm (W) x 15.5 mm (H). The FGRIO Master is a standard footprint FGRO9 plus an IO Interface board on top, differing only in width at 2.75 inches. The dimensions of the FGRIO Master are 140 mm (L) x 70 mm (W) x 34 mm (H).

Q: What timing issues does IO introduce?

A: Although IO mimics a wired connection, the electronics and communication heartbeat

do cause some signal delay. The worst case delay for digital signals in either direction and the Sensor Power command from FGRIO Master to IO Slave is 167 msec, assuming a robust link. Worst case delay from FGRIO Master Sensor Power assertion to FGRIO Master Analog Output refresh is 700 msec.
