3. 4. 4. 5 DC140 Analog Monitor (IO Check)

Description Monitors the analog value of the A/D converted sensor, by operating each component
(such as C.C). You can temporarily change the output value. You can also check the Input
Component and Output Component simultaneously.
Procedure
1. Select the "IO Check" tab on the Service Mode screen.
2. Select [DC140] on the IO Check screen.
3. The Analog Monitor screen is displayed.
• The Analog Output Component names and the Analog Input Component names are
displayed in the table in the sequence of Chain Link No. together with the Chain Link
No.
• All the status display of the appropriate output components show "Disable" (checking
stopped). Display of the Level column is blank. All the status display of the
appropriate input components show "Disable". Display of the Input Value column is
blank.
The figure uses the screen when both input component and output component are
selected for execution.
4. Carry out the Output Component Check items.
<Output Component Check>
(1) Select the target components.
(2) Select [Execute] of the Output Component Check.
(3) The corresponding output component of the Main Processor is turned On at an
output level based on the Output Level Value (value specified only for the test).
(4) The PSW changes the status display of output components to "Enable" (Checking in
progress) and displays the Output Level Value received. (Level: 0~1000)
• Other components required for checking the applicable output component of the
Main Processor are also turned On.
• The components which are turned On only for the limited period of time will be
automatically turned Off after they were turned On for the specific period of time.
• If the PSW is instructed to turn On a component which cannot be turned On at the
same time with another component which is already turned On, the component
previously turned On will automatically be turned Off. (Last Precedence Control)
When the component cannot be automatically turned Off, "[!] Unable to check this
component. Stop the other output components." is displayed.
(5) When you want to check several components at the same time, repeat Step 4 -
<Output Component Check> from (1) to (4). The maximum no. of output
components which can be checked at the same time is 5. When the 5th output
component was instructed for checking, selection of [Execute] becomes invalid.
(6) If you want to stop checking of the target components being selected, select [Stop]
or select [Stop All] to turn Off all the output components.
(7) Turns Off an appropriate output component. The status display of the appropriate
output component selected shows "Disable" The display of the Level becomes
blank.
(8) There are 2 methods to change and check the Output Level of the output component
temporarily. Procedure A uses the Change Output Level Screen by selecting
[Change Output Level]. Procedure B uses [Level+] and [Level-] to add/subtract the
Output Level Value by 1 at a time. Go to Step (9) when using [Change Output
Level]. Go to Step (14) and the subsequent steps when using [Level+] and [Level-].
(9) Select the desired components for changing the Output Level in "Procedure A" and
select [Change Output Level].
Both components status showing either "Disable" or "Enable" can be selected.
(10)The Change Output Level screen is opened.
(11) Input the new Output Level by using the keyboard, select [OK] to close the Change
Output Level screen and display the Analog Monitor screen.
(12) The new output level is added or subtracted for inputting, and the new output level
will be displayed in the level column of output components on the Analog Monitor
screen. If the output level value input is out of the range, the message "[!] The value
entered is out of the specified range. Enter the value again." will be displayed on the
Information screen. (Out of the specified range means that it is out of the Upper and
Lower Limits data range set up in the Main Processor.)
(13)For the subsequent procedures, repeat and check Procedure 4 - <Output Component
Check> from (2) to (12).
(14)Select the desired components for changing the Output Level in Procedure B and
select [Level+] or [Level-].
(15)Adds/subtracts the Output Level Value by 1 at a time. The new output level is added
or subtracted for inputting, and the new output level will be displayed in the Level
column of output components on the Analog Monitor screen. If the output level
value input is out of the range, the message "[!] The value entered is incorrect. Enter
the value again." will be displayed on the Information screen. (Out of the specified
range means that it is out of the Upper and Lower Limits data range set up in the
Main Processor.)
(16)For the subsequent procedures, repeat Procedure 4 - <Output Component Check>
from (2) to (15) (except from (9) to (13)).
5. Select [Close] to return to the IO Check screen after checking of the Analog Monitor has
completed.
