2.3 Application Settings
Simple CPU Communication Setting (CPU Module (Built-in
Ethernet Port Part))
Set the following items when using the simple CPU communication function with the CPU module (built-in Ethernet port part).
Item Description Setting range
Latency time Sets the time required to start communications after completion
of the CPU module startup.
This setting is common to all the setting numbers and cannot be
changed for each setting number.
0 to 255s (in increments of 1s)
(Default: 0s)
Setting No. Displays setting No.1 to 64.
An arbitrary setting number can be set. (A number that is not
sequential can also be set.)
Communication pattern Sets whether to read or write data. • Read
•Write
(Default: Blank)
Communication setting:
Execution interval (ms)
Communication setting Sets this item to communicate data periodically. Fixed
(Default: Fixed)
Execution interval Sets the execution interval of communications when "Fixed" is
set for the communication setting.
10 to 65535ms (in increments of 1ms)
(Default: 100ms)
Communication
destination (IP address)
Source Sets the transmission source.
When the communication pattern is set to "Write", the own
station (IP address of the own station) is displayed.
Page 279 Communication
Destination Setting
Destination Set the transmission destination.
When the communication pattern is set to "Read", the own
station (IP address of the own station) is displayed.
Target PLC No. Specifies the target CPU number for the communication
destination.
It will be the connected station when "Not Specified" is selected.
• Not Specified
• PLC No.1
• PLC No.2
• PLC No.3
• PLC No.4
(Default:Not Specified)
Bit device Points Set the type, start number, and end number of the "Source" bit
device and the type and start number of the "Destination" bit
device. When these values are input, the number of points will
be displayed automatically.
The setting range differs depending on
the communication destination. (

Word device Points Set the type, start number, and end number of the "Source"
word device and the type and start number of the "Destination"
word device. When these values are input, the number of points
will be displayed automatically.
Type
Start

Communication time-out period (ms) Sets the time period until the retry is performed, the time period
until a communication error occurs, and the time period to wait a
response from the communication destination after an error
response from the communication destination.
Configure the setting so that (communication time-out period)
(execution interval).
For details on the communication time-out period, refer to the
following.

Retry Count/Monitoring Time At Error
10 to 65535ms (in increments of
1ms)
*1
(Default: 1000ms)
Communication retry count Sets the number of communication retry to be performed within
the communication time-out period when the communication
destination returns an error response or does not respond.
For details on the communication retry count, refer to the
following.
Page 187 Communication Time-out Period/Communication
Retry Count/Monitoring Time At Error
0 to 255 times
*2
(Default: 3)
Monitoring time at error (s) Sets the communication time after a communication error
occurred.
For details on the monitoring time at error, refer to the following.
