It would be very costly to replace this processor. What follows is a brief description of your processor.

The processor you discribed is Modicon Unity Quantum processor. It has a 486 processor at 800kb, 2M SRAM, 2 Modbus Ports, 1 Modbus Plus Port. It come loaded with the Unity operating software and you use Unity Pro Software for programming.

thanx for the reply..
have u used this processor..is it consistent using this processor. ours is a material handling plant and this processor drives about 700 I/O's .sometimes in future, if the processor shutdowns or faces some problem,the suppliers will plead their inablility to help since the proccesor is obsolete.
so to play it safe i was asking the substitute version.
thank you

This Processor can be migrated to 140CPU53412. sO THAT THE SAME LOGIC CAN BE USED. We have done many projects like this.

The 140CPU53414A is obsolete. But you can use the CPU 140CPU53414B.
The 140CPU43412A is not obsolete yet.
