Schneider Modicon Quantum CPU140CPU67160

This Modicon Quantum CPU has been designed to manage the Hot Standby functionality for the programmable logic controllers within the Schneider Electric Quantum series. To protect the application programme from inadvertent changes during operation, it is stored in a battery backed internal RAM. The processor is easy to use and features an LCD display to access diagnostics, access certain configuration parameters and starting and stopping the CPU. The processor battery is easy to access and service as it is located on the front of the unit and can be changed whilst the CPU is in run mode. The Hot Standby system is compatible with Unity Pro™ XLS software, and provides the CPU with the high level of availability required by the critical process applications.

Features and Benefits

Modicon Quantum 140CPU67160 Technical FAQs

1、What could cause my Quantum 140CPU67160 to come up as ‘NO CONFIG’ after a power cycle?

One possible cause is that the PLC is using a PCMCIA card in slot 1 that has a bad battery. A bad battery is indicated by PCM1 with the number flashing on the LCD display. In PLC logic, %S67 (PCMCIABAT0) can be monitored.

2、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.

3、Which Quantum PLCs are supported in Unity Software?

The following PLCs are supported: 140CPU67160

4、Which Quantum PLCs have the Factory Mutual (FM) Class 1 Div. 2 rating?
