The drawing shows the setup dialog box for Modicon Modbus (Serial). Enter the PLC ID (PLC
address). The default setting for Timeout is correct for most applications.
The user can now select the storage format (word order) for float and dword data types.
When tags are created automatically, the address field will be padded with zeros if you entered the
original tag with preceding zeros. A four digit field will be used if you entered a 4 digit number, else a
five digit field will be used by default. Note that you must type the original tag in correctly.
The single write command check box allows the user to select between the multiple write commands
currently supported by the Modbus protocol and single write commands supported by previous
versions of Modbus.
When this box is not selected (default setting) it supports the multiple write commands of Modbus.
When the box is selected, the protocol will support only single write commands.
