Modbus to EtherNet/IP Tag/File Configuration Page
This is the configuration line number.
•
If the configuration entry has been saved, the line number is not directly
modifiable.
•
If the configuration entry is in the process of being added and has not been
saved, then the line number can be set to anywhere in the configuration
list.
-
The placement of the entry in the saved list is in relation to the current
list of saved entries. For example, if you wish to place an entry before
the current 4th entry, then enter 4 for the line number.
-
If more than one entry is added at one time, the order is preserved but
final line numbers may or may not be the same as the selected
numbers.
If selected, the configuration becomes active when the Save button is clicked on.
Data Mapping immediately begins to perform the configured operations.
If not selected, the configuration becomes inactive when the Save button is
clicked. Data Mapping then ignores the configured operations.
The Modbus Device ID to be read.
•
If access to the Shared Memory is desired:
-
The Shared Memory must be enabled.
-
The Shared Memory device ID must be entered.
•
If a Device Id for a Modbus slave is entered, the DeviceMaster EtherNet/IP-
Modbus gateway routes the message to the appropriate location.
Select the Modbus Read function code:
•
01: Coil Status (00x) - read one or more coils
•
02: Input Status (10x) - read one or more discrete inputs

Enter the Modbus address in Base 1 format. (The address of the tables starts at
1, instead of 0 for Base 0).
Enter only the lower 16 bits of the address (1-65536).
Enter the number of registers or coils to be read.
Enter the rate at which the Data Mapping process should read the configured
Modbus device or Shared Memory.
If selected, the Data Mapping process only writes the received data to the
EtherNet/IP location if:
•
The data is being received for the first time.
•
The received data has changed.
•
The previous write attempt to the EtherNet/IP location was unsuccessful.
