1
It is validated only via Explicit message communication. If this data item is set as a measured data item
(IN) or setting data item (OUT) by the “Controller communication item setting object (0xC7: C7Hex)”
which sets communication data items via polling I/O communication, it becomes the same as that when
set at “0.” In addition, any data item set hereafter is invalidated.
2
Only object instances 1 is valid.
3
The COM-JH starts collecting data on connected modules just after the power is turned on, and
communication is validated after data collection is finished. If “Number of connected controller in
controller communication” is read during data collection, “0” is returned. Therefore, the communication
enable state after the power is turned on can be checked as far as “the number of connected controllers”
is monitored.
4
When the set value is “0”, the number of data is the value set by DIP switch. When the set value is 1 to 5,
the number of data is 5. When the set value is 6 to 200, the number of data is the set number of data.
5
Only object instances 1 to 31 are valid.
6
Set the address (0 to 99) of the controller connected to the COM-JH. Communication will only be
performed with the controller whose address is set. If 0 or an address outside the setting range is set,
communication will not take place with that controller and each of the communication item parts will be
filled without spaces. If the address is other than “0” and a controller is not connected, the data will be “0.”
7
When the setting is set to “1: Execute the automatic acquisition” and the power of the COM-JH is turned
off and then on, the address of the controller is automatically acquired. The address acquisition range is
1 to 99, and when automatic acquisition ends, the automatic acquisition of controller setting reverts to
“0: Do not execute the automatic acquisition.” When automatic acquisition of controller address is
performed, the set value of the controller address setting (attribute ID: 245) changes. Controller
addresses are set without spaces from the lowest address, and “0” is set for parts that do not have a
controller connected.
8
If this data item is set as a measured data item (IN) or setting data item (OUT) by the “Controller
communication item setting object (0xC7: C7Hex)” which sets communication data items via polling
I/O communication, it becomes the same as that when set at “0.” In addition, any data item set hereafter
is invalidated.
