Engineering position

Ethernet and RS485 remote I/O module for the industrial data layer

The product belongs to the acquisition and information layer: it records, converts, exchanges or publishes process and machine data. Deterministic machine or process control remains in the controller; logging, remote I/O and IIoT functions should be designed as a separate information path. Distributed mixed-signal remote I/O for extending PLC/SCADA systems over Modbus TCP or Modbus RTU.

Field-data integrationDefine field signals, channel count, acquisition purpose and the receiving PLC/SCADA/MES/cloud system.
Commissioning and diagnosticsProvide software access, network settings, firmware baseline and a repeatable commissioning procedure.
Documented protocol operationConfirm protocol role, addressing, network topology, security and data ownership for the selected model.
Current product position: Current DigiRail Connect positioning is remote mixed-signal I/O for extending automation systems through Ethernet/RS485 and Modbus roles.
System role

DigiRail Connect signal and system architecture

The architecture separates the field/process interface, the NOVUS function and the downstream control or information path. Exact electrical interfaces, protocol roles and accessories remain model-dependent.

Application scope

DigiRail Connect application environments

These application classes indicate the engineering context. Final selection still depends on the exact range, I/O, communication, installation and performance requirements.

01

Distributed machine I/O

For distributed machine i/o, define the source signals, acquisition rate, record-retention requirement and destination system before selecting the communication and storage architecture.

02

SCADA signal acquisition

For scada signal acquisition, define the source signals, acquisition rate, record-retention requirement and destination system before selecting the communication and storage architecture.

03

Panel retrofit

For panel retrofit, define the source signals, acquisition rate, record-retention requirement and destination system before selecting the communication and storage architecture.
