3.1.2 Specifying monitoring interval
You can continue to monitor the I/O state of the Rhio232 at a specified time interval by setting
[Setting Monitor Interval]. The valid value for monitoring intervals is any number between 2 and
10 seconds. In the specified time interval, Rhio Manager sends a state request command and
receives a response from the Rhio232 and displays it on the screen.
Figure 3-2 Setting Monitoring Interval
3.1.3 Monitoring I/O port
Upon receiving a state request command from Rhio Manager, the Rhio232 returns information
on the overall states of the digital input, analog input and digital output ports.
-Digital Input Port shows the ON/OFF state of input.
-In Level mode, ADC Input Port converts the analog value retrieved to a digital value in
1,024 steps and displays the converted value (“0000”-“1023”).
-In Switch mode, ADC Input Port compares the input value to a specified threshold value
and displays ON if it is higher and OFF if not.
-Digital Output Port displays the ON/OFF state, operation condition for an output port,
and standby state.
3.1.4 Controlling digital output port
You can place your mouse over the Digital Output Port LED of Rhio Manager and left-click it to
control ON/OFF state.
-When the operation condition for a digital output port is not specified, the ON/OFF state
for the port is toggled each time you left-click your mouse.

18
-When the operation condition is specified, the port is set to ON if it is met, and it is set
to OFF and displayed as a standby state if not.
-After output control is completed, the Rhio232 returns the states of all ports to the host
computer.
3.2 Digital Input Setting
The Rhio232 has 12 digital input ports. You can enable/disable each of these digital input ports
with Rhio Manager or by issuing the commands specified in "Ch. 4 I/O Port Related Protocols".
When setting the digital input with Rhio Manager, place your mouse cursor over the Digital Input
LED on the I/O Port Control screen and right-click it to display the Setting window.
3.2.1 Setting Enable/Disable
Figure 3-3 Setting digital input
Digital input setting has two options: Enable and Disable. After selecting either of the options,
press the [Setting] button to apply it in the system. A port cannot be set while it is operating in
Run mode. Therefore, Rhio Manager sends a command that switches its mode to Setting mode
first and then issues the set command when its operation is stopped.
When set to Enable, Rhio Manger receives the ON/OFF state from the device connected to a
digital input port and then displays it. When set to Disable, it displays Disable regardless of the
ON/OFF state of the device connected to the input port.

19
3.3 Digital Output Port Setting
The Rhio232 has 10 digital output ports. You can set each of these digital output ports with Rhio
Manager or by issuing the commands specified in "Ch. 4 I/O Port Related Protocols". Place your
mouse cursor over the Digital Output Port LED on the I/O Port Control screen and right-click it to
display the Setting Output Port window.

3.3.1 Setting Enable/Disable
Set a specified port to Enable/Disable by selecting the [Port Enable] and [Port Disable] check
boxes. If it is set to Disable, the digital output port becomes fixed to OFF.

20
3.3.2 Setting run condition
When the [Macro] check box is selected, you can enter a conditional expression and then use it
to control operation of an output port. Enter the desired conditional expression in the [Macro]
box.
-Specify an operation condition for each output port.
-An output port that has not been set is regarded as a port available for direct control.
-The final value obtained from a logical operation on the listed expression becomes the
state of an output port.
-If the operation condition expression is cleared, a port becomes available for direct
access.
-Operation condition expressions can be specified as follows:
1) Port No. + Logic Expression (&,|) + Port No.
2) Logic Expression (!) + Port No.
3) Port No. + Logic Expression (&,|) + Logic Expression (!) + Port No.
(Logical operator "!" can only be effective before the relevant port no.)
예) - Input #1 AND Input #2
I1&I2
- Input #1 OR Output #2
I1|O2
- The Inverse of Input #1
!I1
- Output #2 AND Output #3 AND the inverse of Output #4
O2&O3&!O4
-A single logical expression can contain up to 21 ports.
-If a port is directly set to ON when its operation condition is not met, it goes into
standby state.
-A port goes into the ON state if its operation condition is met and into OFF and standby
states if not.
-If a port is directly set to OFF, it does not operate even if the operation condition is
satisfied.
