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 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.
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 accepts commands from an attached master unit (client) on the network and generates unsolicited messages. These sets of messages are either spontaneous or cyclic.This data can be derived from the PLC processor. The remote master device can control data in the PLC processor using standard control messages supported by the protocol. The remote master device uses the fully-configured databases in the module to control outputs and monitor inputs.
- 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
Physical Specifications
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.
