Selection Guide
Use the following criteria to determine whether the GPM5.1 or an alternative is the right choice for your application:
- Step 1 – Identify your rack: Confirm your existing Series 90 rack model and available slot count.
- Step 2 – Check firmware version: Retrieve the current firmware version from your existing CPU to ensure backward compatibility.
- Step 3 – Assess I/O requirements: Count total discrete and analog I/O points to confirm the CPU’s capacity meets your needs.
- Step 4 – Evaluate memory needs: Determine program memory and data table size requirements for your application.
- Step 5 – Confirm communication needs: Identify required protocols (Ethernet, Genius, serial) and select a CPU with matching ports.
- Step 6 – Contact Konmask: Send your existing part number and system details to [email protected] for a verified recommendation.
