Describes the installation, usage, and functionality of the SoftPLC version 4 TLM for the master (or client) side of the Modbus TCP/UDP protocol.


• SoftPLC Modbus Serial RTU Master TLM
Describes the installation, usage, and functionality of the driver for SoftPLC version 4 for the Modbus Master RTU protocol, used to communicate with I/O and other devices on RS-485, -232 or -422.


• SoftPLC ModbusTCP/UDP Slave Driver TLM
Describes the installation, usage, and functionality of the SoftPLC version 4 for the slave (or server) side of the Modbus TCP protocol, used to communicate to HMI/SCADA or controller peer-to-peer over Ethernet.


• SoftPLC Modbus Serial Slave TLM
Describes the installation, usage, and functionality of the driver for SoftPLC version 4 for the Modbus slave protocol, used to communicate between intelligent devices on RS-232, -485, or -422.


• SoftPLC A-B Remote I/O Scanner (Master) Driver TLM
Describes the installation, usage, and functionality of the Allen-Bradley Remote I/O (RIO) Scanner driver for SoftPLC's internal interface.


• SoftPLC A-B Remote I/O Adapter (Slave) Driver TLM
Describes the installation, usage, and functionality of the Allen-Bradley Remote I/O Slave TLM, which enables a SoftPLC to emulate remote racks on an Allen-Bradly Remote I/O network via its internal interface.

SoftPLC TLM's/TLI's TOP

These loadable modules and instructions are included in each SoftPLC and Gateway product, and are updated via the package management system.

• COMGENIUS
Instructions which enable SoftPLC to perform general purpose ASCII communications to/from serial devices. This TLM includes implementation of a simple Modbus Master protocol.


• Logger
Describes the installation, usage, and functionality of the add-on instruction for SoftPLC version 4 which provides the capability to log a group of data values to comma-separated values (CSV) text files, plus information on how to copy the file to an alternative location, such as a USB memory stick or network drive.


• LogData
Instruction which enables SoftPLC to log data to a binary file. Includes utility to convert binary log file to ASCII for use with spreadsheets or database programs. Useful for high-speed, high volume data logging.


• Send Mail
An add-on firmware option for SoftPLC version 4.x and later (Cat No SPZ-MSG) which provides the capability to send SMTP emails or text messages.
