IEC60870-5-104 Server Communications Module
MVI71-104S
The MVI71 IEC 60870-5-104 Server Communication Module allows PLC backplane I/O compatible processors to interface easily with IEC 60870-5-104 protocol-compatible clients and hosts.
Features and Benefits
The MVI71-104S 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 PLC 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 - 1771 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.
Applications
The MVI71-104S module is 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 MVI71-104S module can accept commands from an attached Client (Master or Host) on the network and can generate unsolicited messages. Unsolicited messages can be sent based on events or on a time cycle. The remote Client uses the fully-configured databases in the module to control outputs and monitor inputs and can modify data in the PLC processor using standard Control messages supported by the protocol.
- Supports clock synchronization commands
- Supports clock synchronization (set in ladder) from the module to the processor, or from the processor to the module
- Supports group interrogation
- Processes information in control direction and monitored direction
- Configurable monitored and command data located in the MVI database
- Supports timestamp events
PLC Interface
- Operation via simple ladder logic
- Complete setup and monitoring of the module through RSLogix 5 software
- PLC backplane interface via block transfer or side-connect interface
- All data related to the module is contained in user-defined files.
