Schneider CPUs 140CPU31110C Technical FAQs
1、Which Quantum PLCs allow the use of an Aux task in Unity?
The 140CPU65150, 140CPU65160, and 140CPU67160 allow the use of Aux tasks numbered 0 thru 3. The 140CPU31110, 140CPU43412A, and 140CPU53414A will only allow the use of a Fast and a Mast task.
2、Which Quantum PLCs are supported in Unity Software?
The following PLCs are supported:
*These two controllers require a new Exec file to function with Unity
3、What do the Memory Protect slide switch settings signify in the 140CPU31110?
Mem Prt Off – allows run/stop CPU and application changes.
Not Used – should not be used as it can lead to undefined operation. Produces “Error while trying to run the project;
mode cannot be changed (ex: an I/O forces the PLC to STOP)” when the user tries to run/stop CPU or
Mem Prt On – prohibits run/stop CPU or modification of applications.
4、Can I create a Quantum Hot Standby configuration running one 140CPU53414A PLC with Unity firmware and one with NxT firmware?
No. When using an NxT configuration in hot standby, both PLCs must have NxT firmware. When using a Unity Quantum hot standby configuration, only specific hot standby controllers can be used. The 140CPU43412A and 140CPU53414A PLCs are not supported in Unity Hot Standby configurations.
5、What does “basic OS loader invalid checksum” displayed on a Unity Quantum 140CPU6XXXX indicate?
This error can be seen if there was an interruption to the Executive Flash process. Sometimes the PLC is recoverable and sometimes it is not. To recover, some of the actions listed below can be attempted. Remove any PC cards installed in the PLC and any cards other than the PLC and PS from the back plane. If available, try a different power supply and back plane.
Power off, press and hold the ESC key through power up.
Press the Restart button next to the battery.
Use the OS Loader to connect to the PLC using either Modbus or MB+, set to address 1 and attempt to flash firmware.
Power off, remove battery, remove from back plane, let sit 120 minutes and power on.
If after the above actions the PLC does not recover, it must be returned for repair/ exchange.
