Presentation of the LTMCUF Control Operator Unit

Aim of the product

HMI FDR services facilitate operator task when replacing a drawer in a high continuity of service environment, without needing a computer nor expertise in configuring LTMR

Description

The reference LTMCUF includes all the LTMCU reference features.

In addition LTMCUF integrates the FDR services: Fast Device Replacement.

A non-volatile memory of 8MB enables LTMR’s memory (configuration and custom logic files) to be saved.

LTMCU will not integrate the FDR services.

FDR services are provided by the LTMCUF HMI itself that will allow users to backup and restore LTMR’s memory into LTMCUF’s memory.

These services don’t need a network connection and thus no PLC like on Ethernet FDR services.

They are:

• available for all LTMR references whatever the communication protocol (Modbus, Canopen, DeviceNet, Profibus, Ethernet),

• independent from the power supply type.

In case Ethernet DHCP addressing mode is used, HMI FDR is disabled to avoid priority conflict between Ethernet FDR and HMI FDR
