IEC 60870-5-104 Server Communication Module

MVI56-104S

The MVI56 IEC 60870-5-104 Server Communication Module allows ControlLogix backplane I/O compatible processors to interface easily with IEC 60870-5-104 protocol-compatible hosts.

Features and Benefits

The MVI56-104S module acts as an input/output module between the IEC 60870-5-104 Ethernet network and the Rockwell Automation backplane. The data transfer from the ControlLogix processor is asynchronous from the actions on the network. A 4000-word register space in the module exchanges data between the processor and the Ethernet network.

General Specifications

• Single Slot - 1756 backplane compatible
• The module is recognized as an Input/Output module and has access to processor memory for data transfer between processor and module
• 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
• Local or remote rack

Applications

The MVI56-104S 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 MVI56-104S 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 ControlLogix 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 ControlLogix 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 ControlLogix
• 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 MVI56 is available which fully documents data types supported by the module.
