140CPU43412U Technical FAQs

1、Is function 15 for the MBP_MSTR block supported with a 140CPU43412U PLC?

Yes.
MBP_MSTR function code 15 has the following requirements at minimum;
NOE77101 version 5.0
NOE77111 version 5.0
Unity Quantum CPU (includes 534 and 434) Exec firmware version 3.0
Unity 6.0
The CPU native Ethernet port or MB+ ports do not support this function, NOE only.

2、What is the replacement for the 140CPU43412A?

The replacement is the 140CPU43412U.

3、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.

4、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.

5、Which Quantum controllers support Concept IEC Hot Standby?

The following Quantum controllers support Concept IEC HSBY:
140CPU43412
140CPU43412A
140CPU53414
140CPU53414A
140CPU53414B
