Frequently Asked Questions (FAQ)
Q1: What distinguishes the 140CPU67160C from other Quantum CPUs?
A1: The 140CPU67160C features a powerful 66 MHz processor, fast instruction execution (0.05 µs), and enhanced memory support, making it ideal for large-scale, mission-critical applications.
Q2: Can I use Ethernet communication directly on this CPU?
A2: The CPU does not have native Ethernet; however, it supports Ethernet via an additional NOE module, allowing integration with TCP/IP networks.
Q3: Is this CPU compatible with Unity Pro software?
A3: No, the 140CPU67160C is programmed using Concept or ProWORX 32 software. It is not compatible with Unity Pro, which is for Modicon M340/M580.
Q4: What is the memory capacity, and can it be expanded?
A4: The CPU comes with 4 MB RAM and supports additional memory via a PCMCIA card, allowing configuration backups and application data storage.
Q5: How many I/O modules can be connected to this CPU?
A5: The CPU supports up to 64 local I/O modules on the Quantum backplane, with the ability to expand via remote I/O architecture.
Q6: Can this CPU operate in outdoor environments?
A6: While it is robust, it is designed for indoor industrial environments. For outdoor use, proper enclosures and environmental protection are necessary.
Q7: What power supply is required for this CPU?
A7: The CPU requires a 5 V DC supply, provided through the Quantum rack’s backplane. Power modules like the 140CPS11420 can be used.
Q8: Is hot-swapping supported?
A8: Yes, the Modicon Quantum platform allows for hot-swapping of I/O modules, though the CPU itself should not be removed during live operation.
