If a project with a different I/O Driver version is transferred, it takes time to start the display unit.
If there are many PDO data, the number of processes executing the logic increases, so scanning may take longer than the set scan time.
Depending on the I/O driver settings, when the CANopen communication cable is disconnected, the CANopen network is reset upon restoration.
The number of I/O bit points you can set up is 1024 (input bits: 512 points, output bits: 512 points). The number of I/O integer points you can set up is 256 (input integer: 128 points, output integer: 128 points).
Please do not set values outside the valid range. Even if you set up a value outside the range, an error may not display.
If you open the network setup dialog box, despite not making any changes, a save project message may display when you close the project.
After mapping I/O, deleting objects, disabling PDO, or deleting the slave will not cancel the I/O mapping.
When using the CANopen driver, the undo operation is not available in the associated I/O screen or I/O driver settings.
While the LT3000 Series unit is powered ON, such as when it is running, do not install or remove the LT3000 Series unit to/from the CANopen master unit manufactured by Digital Electronics Corporation.
When mapping a variable to an I/O terminal on the I/O screen, do not use any array variables. It will not operate normally.
In the PDO settings, set up TPDO and RPDO to a maximum of 252. If TPDO or RPDO is set to more than the maximum of 252, the "Compile error" message may appear.
If the baud rate is changed, all the equipment connected to the CANopen network must be turned on again. Slave devices with auto baud rate setting must be turned on again as well.
When powering up the master and slaves separately on the CANopen network, the CANopen slaves (HTB and others) must be powered up first, and then the CANopen master (display unit or other) must be turned on last. Otherwise, the CANopen network may not operate properly.
When using the CANopen driver in the project, please make sure the Windows user account for editing the project uses only ASCII characters. If the user account includes characters that are not ASCII, after editing projects set up with the CANopen driver you will not be able to save them.
When changing the model from LT3000 Series to LT4000 Series, or when changing from LT4000 Series to LT3000 Series, the [I/O Driver] CANopen driver settings are preserved. However, the baud rate and SYNC transmission settings change automatically. For details, refer to the Settings Guide.
31.7.7.2 Master Configuration Dialog Box
When changing to a non-LT model, the CANopen driver settings are deleted.
You cannot use [Copy from another Project] to copy the CANopen driver settings from a project with a different model.
If you run the following operations while the SDOR instruction or SDOW instruction is running, the instruction will be interrupted. Restart the display unit if the instruction does not start even after the Run screen displays.
