Additional Information

The 140CPU53414B is a Modicon Quantum processor for use with ProWorx 32 or Concept software. It includes a mathematical coprocessor and an internal memory of 2972 kB RAM. This unit is functionally identical to the non-B version, with some considerations. If you are using the CPU in a Hot Standby setup, you must use with two non-A, two A, or two B versions. The B version also requires a new flash exec, which is not interchangeable with the A and non-A flash executives. 

The front panel has a slide switch which is used to select the comm parameter settings for the Modbus RS232 ports on the 140CPU53414B. There are three options, the top is for ASCII functionality, the middle is for RTU functionality, and the bottom allows you to assign comm parameters to the port. The CPU hardware defaults to bridge mode when the switch is set to RTU or ASCII mode.
