Professional FAQ

Does the IC693CPU340 support PID control loops?

Yes, it supports standard PID through integer math; however, it does not natively support floating-point instructions.

How is the user program protected against power failure?

The program is stored in non-volatile Flash memory, which retains data without the need for a battery backup.

Can I install this CPU in a 5-slot or 10-slot baseplate?

Yes, as long as it is placed in the dedicated CPU slot (Slot 1) of a Series 90-30 modular baseplate.

What is the advantage of the 80C188XL processor over embedded models?

The 80C188XL offers higher clock speeds and superior management of specialized I/O processor modules.

What should I check if the "OK" LED is not illuminated?

Confirm the 5VDC backplane power is stable and ensure the module is fully seated in the rack connector.
