SCOM Protocol on RBC Manual MAEN993, 2009-12 English
Foreword SCOM Protocol on RBC Foreword The Lauer SCOM Protocol is designed for controlling different Beijer Electronics devices remotely over different kind of interfaces. It is based on the SCOM Protocol, allowing easy replacement of existing units. Besides the standard command set, the Lauer SCOM Protocol includes a rich set of special purpose commands for extended remote controlling options. The SCOM Protocol is extended with these special features, without affecting the compatibility.

Interface Configuration 1 Interface Configuration A command can be sent either using the serial interface (RS232 or RS485) or the USB interface.
Message Format and Description 2 Message Format and Description An SCOM message is a stream of bytes, containing the destination, type of message and the corresponding data, if available. The complete stream is protected by two checksums. Data transfer is initiated by sending a command message. Depending on the command, a response message may be sent back. Some commands may contain sub-commands and data, which are sent in the data field of the message.
Message Format and Description Byte 5 Field LEN Value 0 to 74 (0x00 to 0x4A) Size 1 byte Description The size of the DATA-field in bytes. To protect the message header (bytes 0 to 5), a simple 8-bit checksum is calculated as follows: 6 ICHKH ... 1 byte 1. Calculate the sum of bytes 0 to 5. 2. Reduce the sum width to 8 bits (AND 0xFF). 3. Invert all bits. The result is ICHKH. The checksum is verified as follows: 1. Calculate the sum of bytes 0 to 6. 2. Reduce the sum width to 8 bits (AND 0xFF). 3.
Device Addressing 3 Device Addressing By default, a Beijer Electronics RBC supports the standard SCOM addressing scheme, which allows a total count of 16 devices within a network. The address of a device is set with four DIP switches. If an SCOM command is sent to a device, the ADR field must contain either the broadcast address 0xFF, or the address of the destination device set by the DIP switches. To eliminate this limit, a new addressing scheme is supported by the Beijer Electronics RBC.
Protocol Description and Timings 4 Protocol Description and Timings The protocol used for transferring SCOM messages and receiving response messages is optimized for easy software implementation. Regardless of the type of interface, a connected device is always passive and listening for a command to be received by any available communication interface. A Beijer Electronics RBC never sends SCOM messages by itself, unless it is configured as a remote controller.
Protocol Description and Timings Conditions for Response Message The conditions for a response message generated by the Beijer Electronics RBC are described below: Interface RS232 RS485 USB Address condition Command status Response Address does not match device address not EXECUTED No response not EXECUTED No response Address matches device address if COMPLETED ACK if FAILED NAK Address is Broadcast address (0xFF) if COMPLETED ACK if FAILED NAK Address does not match device address n
Protocol Description and Timings The Lr value depends on the command, for which the response message is generated. Detailed information and the “Maximum Lr value” for each response message can be found in Command Reference chapter. Note: The given “Maximum Lr value” is specified for a valid command. If an invalid command with a data field exceeding the specification is sent, the Lr value will grow accordingly.

Command Reference 5 Command Reference The Lauer SCOM protocol exposes many commands for remote control of a Beijer Electronics RBC by a dedicated software. It supports all standard SCOM commands, as well as the new Lauer command set for special purpose functions. This chapter describes each SCOM command and sub-commands for the currently available device, Beijer Electronics RBC.
Command Reference 5.1 BRT Backlight Brightness Sets the backlight level to the given value. This command affects only the brightness of the backlight lamp or LED array, not the brightness value of the video controller. Supported since Firmware Version LAUER RBC: 0.0.0.

Command Reference 5.6.12 LAU_CONFIG_GETDISPLAYGROUP (0x0127) Device Group Besides the standard addressing scheme, where the lowest four address bits in field ADR are used to address a total count of 16 devices in a network, the Beijer Electronics RBCs use also the upper four bits, that indicate a group of devices in a network (max. 15 groups). This function returns the configured group the device belongs to. It is only used, if the device is configured to override the DIL switch settings.
Command Reference 5.6.13 LAU_CONFIG_GETKEYPRESSMODE (0x012A) Keypress Mode The brightness of the Beijer Electronics RBCs can be configured adopt a determined value if both dimmer keys are pressed for longer than one second.

Command Reference 5.6.14 LAU_CONFIG_SETDILMODE (0x018E) DIL Switch Mode For a base configuration, Beijer Electronics RBCs are equipped with DIL (DIP) switches, where the device address and the serial interface mode can be selected. Besides this configuration option, Beijer Electronics RBCs allow full software configuration, which is stored in an internal Flash memory. The software configuration also includes device address and serial interface mode setting.
Command Reference Example Set the device at address 0.7 (group 0, address 7) in the mode to override the DIL settings (i.e. device address and serial interface mode) with software settings: 0 0x07 1 2 0x07 0x4C 3 0x41 4 0x55 5 0x03 6 7...9 0x0C 0x01 0x8E 10 0x01 0x6F According to the data returned by the device at address 0.
Command Reference 5.6.15 LAU_CONFIG_SETDISPLAYADR (0x018F) Device Address Stores a software address of a device in the internal memory. This address is used, if the device is configured to override the DIL switch settings. Only the address is changed; not the group. Note: The changes made by this command will become active only after a restart of the device. This avoids loosing the connection to the device during configuration. Supported since Firmware Version LAUER RBC: 0.0.0.
Command Reference Example Set the software configured device address (excluding group) from the device at address 14.7 (group 14, address 7) to 8: 0 0x07 1 2 0xE7 0x4C 3 0x41 4 0x55 5 0x03 6 7...9 0x2C 0x01 0x8F 10 0x08 0x67 According to the data returned by the device at address 14.
