IEC60870-5-104 Server Communications Interface Module
MVI46-104S
The MVI46 IEC 60870-5-104 Server Communication Module allows Rockwell Automation SLC backplane I/O compatible processors to interface easily with IEC 60870-5-104 protocol-compatible hosts.
Features and Benefits
The MVI46-104S module acts as an input/output module between the IEC-870-5-104 Ethernet network and the SLC backplane. Data transfer between the module and the processor is asynchronous from the actions on the network. Databases are defined by the user for the module to hold data as required by the protocol.
General Specifications
- Single Slot - 1746 backplane compatible (Local or extended I/O rack only. Remote rack not supported)
- The module is recognized as an Input/Output module and has access to processor memory for data transfer between processor and module using M0/M1 files
- Ladder Logic is used for data transfer between module and processor. Sample ladder file included
- Configuration data obtained from configuration text file downloaded to module. Sample configuration file included
Applications
The MVI46-104S module has been designed to address the application where a device using the IEC 60870-5-104 protocol needs to communication with the Rockwell Automation processor. As such, the IEC server module can be used as a gateway in many SCADA installations in industries such as:
- Power
- Petrochemical
- Water treatment
- Oil and gas production
Functional Specifications
The MVI46-104S module accepts data read/write commands from a master/client on the network. In addition, the module can be configured to generate unsolicited messages in either a spontaneous or cyclic fashion.
The module has 4000 words of user defined internal register space that are accessible to the protocol driver and to the SLC processor memory. Any of the supported database types can be individually located (within the total database size limit of 4000 words) and each database point is mapped within the module and can be assigned to one or more Groups. The supported database point types are:

IEC 60870-5-104 Server Specifications
Operating in the Server mode, the module accepts commands from a Client(s) to read/write data stored in the module's internal registers. This data is easily and continuously transferred between the MVI module and the SLC processor's data registers.
The IEC 60870-5-104 Server functionality supported by the module includes:
- The IEC 60870-5-104 communication driver is built in accordance to the approved IEC specification
- The module functions as a Server on the network supporting data read/write commands from an IEC 60870-5-104 client on the network
- One TCP server socket
- Supports unsolicited messages, either cyclic or spontaneous (cyclic rate is configurable)
- Supports clock synchronization commands from client or from the SLC
- Supports Group interrogation (Global, General 1 to 16, Global Counters, Counters 1-4)
- Event timestamping configurable by type (None, 24 bit, 56 bit)
- Event queue supports 99 points for each data type
- Optional user defined list of acceptable client host IP addresses
- Configurable Common ASDU address (sector) and Information Object Address
- An IEC Interoperability Document for the MVI46 is available which fully documents data types supported by the module
