The Modicon Quantum 140CPU65260 is a Pentium Unity processor with 3072 kB of internal RAM and a clock frequency of 266 MHz. It has 2 local racks, and can have 6 optional modules: Ethernet, Modbus, Modbus Plus, Profibus DP, and Sy/Max. The module has 2 local signaling LEDs – 1 red for Ethernet collision and 1 green for Ethernet activity.
The 140CPU65260 firmware has a long history. The launch version was Unity Pro V2.0. Over time, 50+ changes have been made to a variety for firmware versions, correcting a number of bugs and issues. You should always update your module to the latest firmware revision. Firmware versions greater than V3.30 must be used with Copro version 5.8.
140CPU65260 firmware version V3.5 and all previous versions contain hardcoded backdoors that produce multiple vulnerabilities, allowing hackers (even remote ones) to view firmware, modify the module’s website, modify passwords, and download and run custom firmware.
Overall, the 140CPU65260 has a total of 4 communication ports. One Modbus (RS-232/RS-485), one Modbus Plus (RS-485), one USB, and one Ethernet. The CPU module requires a bus current of 2760 mA. This module also comes with a key switch. Its reference capacity for discrete (bits) is 62 kBytes and its reference capacity for registers (words) is also 64 kBytes. Its battery has a shelf life of 10 years and its service life is 12 mAh. The 140CPU65260 uses a 3V lithium battery.
The CPU module contains a number of built-in diagnostic capabilities. On powerup, it will check and diagnose any issues with RAM, RAM address, executive checksum, user logic, and the processor. While running, it will check all of these functions with the exception of the processor.
