  • Page 7: Chapter 1 Protocol Specification

    Chapter 1 – Protocol Specification CHAPTER 1 ROTOCOL PECIFICATION The MultiLoad auto-detects four low level computer protocols for host communications. Smith Protocol Brooks Protocol Daniels Modbus-RTU Protocol Modbus- TCP/IP Protocol Note: All unknown or not allowed signal or code sequences are rejected and have no impact on the software or measurement data.

  • Page 8: Smith Protocol

    Chapter 1 – Protocol Specification MITH ROTOCOL The Smith protocol is compatible with devices from Smith Meter, such as the Accuload I and Accuload II mini- computer modes of operation. Using this protocol, MultiLoad accepts data in the format: data A1 and A2 are the last two digits of the unit address in the RCU configuration.

  • Page 9: Modbus -Rtu Protocol

    Chapter 1 – Protocol Specification -RTU P ODBUS ROTOCOL The Modbus-RTU protocol has been implemented to be as compatible as possible with the original published Modicon Modbus-RTU standard. Note: The Modbus protocol allows parameter register access only as defined by the explicit mapping in this manual.

  • Page 11: Modbus Register Map Summary

    ERVICES EGISTER Not all commands native to the MultiLoad II have corresponding mapping to Modbus registers. The Extended Services register was implemented as a way to support sending and receiving native Multiload II commands across the Modbus RTU interface. Any native command listed can be sent to the MultiLoad via the extended Services Register.

    Chapter 2 –MultiLoad Responses -TCP/IP P ODBUS ROTOCOL The Modbus-TCP/IP protocol has been implemented to be as compatible as possible with the original published Modbus-TCP/IP standard v1.0b. Note: The Modbus protocol allows parameter register access only as defined by the explicit mapping in this manual.

  • Page 13: Read Holding Registers (Fn=3)

    Chapter 2 –MultiLoad Responses Since Modbus addressing has been implemented in various ways over the years, to avoid confusion in this manual, the Modbus Holding Register addresses listed are the value in the register address field in the message. If it is necessary to know the formal Modbus Holding Register address, simply add 40001 to the register addresses listed in the manual.

    DROPPED OMMUNICATIONS Toptech Systems has specialized hardware that will support multi-dropping of devices on a single RS-232 communication line. This is accomplished by tri-stating or disconnecting the transmitter of a device when it is not transmitting on the communications line. This is similar to the RS-485 multi-dropping method. Due to the tri-stating of the transmitters, the transmit circuit is 'floating' when no device is transmitting.

    AC circuits be protected with optical isolation devices. The RS-232 to RS-485 converters that Toptech supplies provide this isolation. We also provide an RS-232 optical isolation device for RS-232 lines. Similar devices are available from Black Box Corporation and Burr-Brown. One isolation device must be installed on each data communications line.
