Send Mode: Mode used to send an I/O transfer. Available options are:
waitForReply: The Modbus master must wait for an I/O request that it has sent to complete before
sending another request to the remote station.
rapidFire: The Modbus master may send many I/O requests to a remote station before waiting for
responses from the remote station.
Valid Values: Wait for Reply or Rapid Fire
Port: The port that the I/O request is being sent across. The supported ports are: RS232 Port, UDP and TCP.
If UDP or TCP port are selected, the remote station selected for this I/O transfer should have its IP address
defined.
Command Type: The commands used for I/O transfers are:
READ: Used for reading MODBUS registers from the remote station.
WRITE: Write MODBUS output registers to the remote stations.
WRITE_SINGLE: Write a single MODBUS discrete or analog output register to the remote station.
Note:
Only an option when writing a singe discrete output or single analog output.
Local Type: Local Station I/O type. See Table2 - I/O Types and Limits.
Local Relative Address (Required): First address of the local I/O used for the I/O transfer. Valid values are 1
through a value of defined registers configured for specified I/O type. The address ranges are displayed on I/O
Transfer screen under ‘Display of Modbus Default Slave Addresses’ based on configured local register
allocation for specified I/O type.
Remote Type: I/O type on the remote station. See Table2, 3, 4 - I/O Types and Limits.
Note: If modbus WRITE operation is selected, this field should be limited to output register types.
Remote Address: First register address for the remote I/O used for the I/O transfer. Valid values are 1 -
65536.
Number of Registers (Required): Number of registers requested in the I/O transfer. This must be 1, if the
WRITE_SINGLE command is selected. See Table 2, 3, 4 - I/O Types and Limits.
Note: Number of Registers must be 1, if WRITE_SINGLE command is selected.
Create Tags for Range: Create a tag for each local IODB register with custom prefix: IOXF_[Type][Address]
Warning:
Tags will OVERWRITE any existing tags applied to these registers.
Enter Update Interval (ms) (Required): Time interval, in milliseconds, for the I/O transfer. The recommended
value for this field is 500ms or higher.
Scan Enable Type: I/O Type used for controlling and I/O transfer using either a discrete input or discrete
output register. Valid options are DI or DO or Blank if not used.
Scan Enable Address: The address of the discrete register used to control an I/O transfer. Valid values are 0
through number of registers configured for specified I/O type. Blank if not used.
Click on the Finish button to populate the I/O Transfer Table Properties. If more stations are needed, click on the
Add button and enter the required field for each station.
To edit a Remote Station, select the station in the table and click on the edit button. To delete an existing station,
select the station in the table and click on the Delete button.
