FAQ

Q: What is the difference between MVI56E-MCM and MVI56E-MCMXT?
A: MVI56E-MCM is for standard process applications; MVI56E-MCMXT has conformal coating and extended temperature range for harsh environments.

Q: Does it require additional configuration software?
A: No. Configuration is stored in the RSLogix/Studio 5000 project.

Q: Can I replace an MVI56-MCM with MVI56E-MCMXT?
A: Yes, all MVI56E products are backward compatible with MVI56 modules.

Model Selection Tips

• MVI56E-MCMXT = Extended Temperature Modbus Module for harsh environments
• For standard environments, use MVI56E-MCM (lower cost)
• For Modbus TCP/IP, use MVI56E-MNETC or MVI56E-MNETCR
• Verify ControlLogix firmware compatibility
