OMRON SSS Software C-series PLC Operating Instructions

4.2 SYSMAC NET and SYSMAC LINK Data Link

Industrial networks are an important component of modern automation systems. SSS provides powerful data link management capabilities for SYSMAC NET and SYSMAC LINK networks.

Data link table: Data link is the foundation for automatic data exchange between PLCs. SSS allows users to create and edit data link tables offline, defining the data area (such as LR area, DM area) and word count for each node's sending and receiving.

Routing table: In SYSMAC NET multi network systems, SSS needs to configure a routing table to communicate with PLCs on remote networks. The routing table specifies the bridge node addresses required to reach the target network. These configurations can be made in the system settings.

Online network operation: After online, the edited data link table can be transmitted to the PLC through SSS, which can start/stop the data link and monitor the operation status of the data link, such as communication cycle time, refresh cycle time, and error status of each node. This is crucial for the maintenance and diagnosis of network systems.

Part 5: System and File Management

5.1 System Setting Parameters

System settings are the cornerstone of the normal operation of SSS. In addition to the PC models and interfaces mentioned earlier, they also include:

I/O table UM transfer: determines whether the I/O table and/or data link table are also transferred to the user memory (UM) of the PLC during program transfer.

Printer settings: Specify the printer model for printing programs, data lists, etc.

Data disk drive: Specify the default file save path.

Output bit annotation type: Choose whether to display I/O annotations or instruction annotations for output instructions.

5.2 Document Management

SSS supports two file formats: DOS files and LSS files.

DOS file: This is the default format of SSS, with good compatibility, and can be operated using DOS commands.

LSS files: In order to be compatible with older LSS software, SSS also supports saving and reading data in LSS format. The file management menu provides directory display, file copying, renaming, deleting, and directory creation and deletion functions, allowing engineers to efficiently organize project files.

Part 6: Summary and Safety Precautions

6.1 Summary

OMRON SYSMAC Support Software (SSS) is a comprehensive and well-designed PLC development platform. It covers the entire process from project creation, programming, configuration, to on-site debugging, monitoring, and network maintenance through clear offline/online mode division. Its ladder diagram and mnemonic dual track programming mode meet the preferences of different engineers, and powerful online editing and intelligent debugging functions (such as AI search) greatly improve on-site work efficiency. For complex network systems, SSS also provides complete configuration and monitoring tools to ensure efficient and reliable operation of the system.

6.2 Safety precautions

The manual repeatedly emphasizes the importance of safety at the beginning and throughout the entire text, and any operation must follow the following principles:

Personnel safety: It is strictly prohibited to disassemble the unit or touch the terminals when powered on to prevent electric shock.

Environmental safety: Avoid use in environments with extreme temperatures, humidity, corrosive gases, or strong vibrations.

System safety: Before modifying programs, forcing set/reset, or changing PLC operating modes, it is necessary to confirm that these operations will not pose a danger to controlled equipment or personnel. The manual clearly states that failure to comply with these warnings may result in serious personal injury or even death.

Data Security: Before switching display modes or performing critical operations, it is essential to perform a 'store' operation to prevent data loss.

In summary, mastering SSS software is the key to efficiently applying OMRON C-series PLCs. It is not only a programming tool, but also an integrated engineering management platform that provides solid technical support for the entire lifecycle of automation systems.
