Word Monitoring
An alarm is triggered when the value of the monitoring word
address matches with the specified alarm value, or is within the
specified alarm range.
Data Type
Choose the data format of the value stored in [Word Address]
from [Dec], [Hex], or [BCD].
For example:
Dec 10->Hex 000A
Dec 10->BCD 0 (displays "0" because it cannot be converted.)
Sign +/-
Select this if you will be using negative data for the alarm
value. This can only be set when the [Data Type] is [Dec].
Jump
Go to a specific row number.
Auto Allocation
The [Address Auto Allocation] dialog box appears. Configure
settings to allocate addresses from the [Start Address] by
specified increments.
Start Address
Set the Word Address that will start the Auto Allocation.
Number of Added Words
Set the number of Word Addresses (from 1 to Alarm limit -
Current row position + 1) for Auto Allocation.
Increase Address By
Set the number of Words to add during an Auto Allocation, from 0
to 4,096.
Trigger Condition
Set the condition that triggers the alarm. 
Click the icon to
display the [Trigger Condition Settings] dialog box.
History/Log/Active
Displays current display mode set in the [Common] tab.

Number of Units
When [Alarm Type] is set to [Extended], set the number of units
from 1 to 256. Depending on the specified number of units, a rung
for setting the Monitoring Address will be added. You can specify
separate Monitoring Addresses for multiple units of the same
message.
Polling Frequency
When [Alarm Type] is set to [Extended], set the polling
frequency to read the Alarm Monitoring Address. You cannot read the
monitoring address right after starting up the display unit.
Reading the address starts when the defined polling frequency
elapses.
-
When a read operation is started, read requests
for the same block are not accepted until all addresses have been
read.
-
If multiple requests to read blocks at the same
time, read from the small number of blocks.
-
If the state of the Monitoring Address changes
during a read operation, it will be read during the following
polling frequency. Trigger Time/Acknowledged Time/Recovery Time
uses the time when data was read, not the time when the monitoring
address was changed.
-
If there is a read request from a separate
block during a read operation, the block with the earliest request
will be read starting immediately before the current read operation
is completed.
-
The Polling Frequency's actual value (in
seconds) and the average value (in seconds) are stored, block by
block, in the following internal device addresses. Also, if the
actual value exceeds the defined polling frequency even once, the
defined range frequency exceeded bit is set ON. Once the bit is set
ON, it will not turn OFF, even if the actual values are under the
polling frequency. You need to turn the bit OFF manually.
-
The format for the set frequency exceeding bit
is as follows.

Polling Frequency may
not keep the set time due to a load condition in the
environments.
In the actual run-time environment, check the frequency Exceeding
Bit and Polling Frequency Measurement, then adjust the alarm
monitoring address's holding time accordingly.
-
If no data was read because of a communication
error, the data will be read at the next Polling
Frequency.
Read Data From Each Alarm
Specifies whether or not Alarm message data is read.
Number of Addresses
Read data values from 1 to 8. Adds the [Common Address] setting
rows to the set number of addresses. The address setting column
will be available for input in the Alarm List.
Use Same Address
Sets whether or not address data values are read in all the
messages in the block regardless of the Alarm Message. In the
address setting column, you cannot set anything from the second row
onward.
Number
Displays the Alarm Message registration number (Row Number).
Unit Name
When [Alarm Type] is set to [Extended], the number of units set
in [Number of Units] is inserted. Unit names can be specified up to
32 single-byte characters. You can also use data from the Text
Table. When an alarm occurs, the Unit Name + Message is displayed
as the Alarm Message.
-
When using the Text Table data, if line feed is
inserted in the data, the text before the line feed will be
displayed as a unit name. The text after the line feed will not be
displayed.
-
Even if the text table data has multiple lines
or more than 32 characters, only up to 32 characters for a unit
name can be displayed per line.
Word Address
Set the Word Address to monitor the alarm's trigger.
Trigger Condition
Set the alarm value that will trigger the alarm. In the cell,
click 
and the [Trigger Condition]
dialog box appears.
16 Bit/32 Bit
Choose the alarm value bit length from [16 Bit] or [32 Bit].
Alarm Value
Select which range of values stored in the monitoring Word
Address will trigger the alarm. The set range varies depending on
the [Data Type] and [Sign +/-].

Alarm Range
The specified alarm range is displayed.
Specify Alarm Range Specify Normal Range
Set the alarm range as "Lower Limit <=
Address Value <= Upper Limit".
Set the alarm range as "Lower Limit >=

Message
Set an alarm message within 160 single-byte characters.
-
When [Enable Text Table] is not selected, you
can insert up to 5 lines by typing [Alt]+[Enter].
-
If an alarm part is set to [Show History] with
the [Message Display Method] set to [Multiple line display], and
[Enable Text Table] is selected in the alarm editor, the message
displays using the text table's index character number. The alarm
message can be up to 5 lines long. If the message is longer than 5
lines, only the first 5 lines will display.
-
If an alarm part is set to [Show History] with
the [Message Display Method] set to [1 Line display], and the
message uses text table data which uses line feeds, only text
before the line feed displays as the message. Text after the line
feed will not display.
-
You cannot input multiple lines on the GP-4100
series. When importing alarm settings and there are multiple line
messages, only the first row is imported.
Level
Each Alarm Message is ranked by importance from 0 (least
important) to 7 (most important). The initial setting is "0". The
Trigger, Acknowledged, and Recovery colors for each level can be
set with the Alarm Part.
