Description
The PROSOFT MVI56-104S is an IEC 60870-5-104 Ethernet Server Communication Module designed for ControlLogix automation systems. It allows a ControlLogix processor to exchange data with IEC 60870-5-104 protocol-compatible hosts and SCADA systems.
The module operates as an interface between the IEC 60870-5-104 Ethernet network and the Rockwell Automation 1756 backplane. It is recognized by the ControlLogix system as an I/O module and transfers data between the processor and the communication network asynchronously. The module provides a 4000-word register space for data exchange between the ControlLogix processor and the Ethernet network.

❓ FAQ
🔹 Q1: What is the PROSOFT MVI56-104S used for?
A: It is used to provide IEC 60870-5-104 Server communication between a Rockwell Automation ControlLogix processor and compatible Ethernet-based SCADA or control hosts.
🔹 Q2: Is the MVI56-104S a Modbus communication module?
A: No. This model is designed specifically for IEC 60870-5-104 communication. Modbus communication requires a different ProSoft module model.
🔹 Q3: What does Server mode mean?
A: In Server mode, the MVI56-104S accepts communication commands from IEC 60870-5-104 Client devices. Clients can read data from or write data into the module’s configured internal database.
🔹 Q4: Can the module send unsolicited messages?
A: Yes. The module supports unsolicited communication that can be configured as spontaneous event-driven messaging or cyclic timing-driven messaging.
🔹 Q5: What ControlLogix hardware is required?
A: The module is designed as a single-slot module compatible with the Rockwell Automation 1756 ControlLogix backplane.
🔹 Q6: Does the module require an Ethernet IP address?
A: Yes. The Ethernet interface requires a static IP address that is unique on the connected network.
🔹 Q7: Can the module be installed in a remote rack?
A: Yes. The MVI56-104S supports installation in local or remote ControlLogix rack architectures, depending on the overall system configuration.
🔹 Q8: What should be checked before replacing an existing module?
A: Verify the complete model number, communication protocol, ControlLogix chassis compatibility, Ethernet configuration, IP address, existing ladder logic, and application requirements before installation.
🔹 Q9: Is Power over Ethernet supported?
A: No. The module documentation states that it should not be connected to Ethernet equipment or networks supplying power over the Ethernet cable.
🔹 Q10: Is this model suitable for spare parts inventory?
A: Yes. For facilities using existing IEC 60870-5-104 communication architectures, maintaining a compatible spare module can help reduce downtime, especially where legacy communication hardware is already installed.
