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.
Some of the major extensions are:
• Special purpose command set available with the new SCOM command “LAU”.
• Extended address field functionality, which enables device grouping, allowing a total count of 240 devices in a network (15 groups, 16 devices in each group).

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.

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:
Calculate the sum of bytes 0 to 5.
1.
Reduce the sum width to 8 bits
2.
(AND 0xFF).
3.
Invert all bits. The result is ICHKH.
The checksum is verified as follows:
Calculate the sum of bytes 0 to 6.
1.
Reduce the sum width to 8 bits (AND
2.
0xFF).
3.
The result should be 0xFF.
Optional field.
If the LEN-field is not 0, this field contains
sub-commands and/or data for the
specified command. If the LEN -f ie l d is 0,
no data is avail a bl e .
Optional field. Only sent if data is
available (LEN ≠ 0).
T o protect the data (bytes 7 to 7+(LEN-1)),
a simple 8-bit checksum is calculated as
follows:
1.
Calculate the sum of bytes 7 to
7+(LEN-1)
2.
Reduce the sum width to 8 bits (AND
0xFF)
3.
Invert all bits. The result is ICHKD.
The checksum is verified as follows:
1.
Calculate the sum of bytes 7 to 7+LEN
2.
Reduce the sum width to 8 bits (AND
0xFF)
3.
The result should be 0xFF
As shown in the table, the DATA field is optional. If the message does not require
any data, the value of LEN is 0 and the field ICHKD is not used and not sent. In
this case the message has the minimum SCOM size of 7 bytes (bytes 0 to 6).
If a command requires data to be sent, the maximum size of an SCOM message is 82
bytes. This means, that the last field ICHKD is located at the offset of the first data
byte plus the value of the LEN field.
The maximum value of the LEN field is 74, which is calculated as:
[LEN] = max. message size - (min. message size + ICHKD size)
or
82 - (7 + 1) = 74

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.
According to the previous chapter, the width of the ADR field is 1 byte (or 8 bits).
The standard SCOM addressing scheme uses only the lower 4 bits of this field (only
in case of the broadcast address, all bits are used), allowing a maximum of 16 addresses.
Related information
Message Format and Description
The new addressing scheme, implemented in Beijer Electronics RBC, uses also the 4
upper bits. To distinguish between the standard and new addressing scheme, these
bits are called “group bits” or simply “group”. Based on this definition, the following
table shows field ADR in more detail:
ADR bits 15...8 ADR bits 7...0
Group
(0 … 14)
Address
(0 … 15)
As shown in the table, a group between 0 and 14 can be specified. Group 15 is not
supported, to avoid address collision with the broadcast address. Thus, together with
the address field, a total count of 15 x 16 = 240 devices can be connected to one network.
Grouping of devices is activated only, if the devices are set up to use the software configured address, instead of the hardware address specified by the DIP switches. If the
device uses the hardware address, the group address is automatically set to 0, regardless of the group configuration.
Beijer Electronics RBC addresses are always given in a dotted notation as “group.address”. This means, if a device belongs to group 7 and its address is 3, the resulting
address will be 7.3, which is 115 (0x73). In the standard mode (i.e. DIP switch address is used), the device address will be 0.3 (or simply 3) for the given example, because the group bits are set to 0.
If a Beijer Electronics RBC is configured as remote controller (default), it addresses
all reachable devices by sending a broadcast command.
8 Beijer El ectr onics, MAEN99 3
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.
If a device receives an SCOM message from any interface, it verifies the message and
checks the address field ADR. In case of an address match between the received address and the device address, the command is processed.
If the broadcast address 0xFF is received, a command is always processed by any device in the network. Depending on the received address and the type of the interface,
a response message (ACK or NAK) might be sent back to the interface, from which
the command was received.
If a device is individually addressed and a serial port (RS232 or RS485) is used, the
next command shall not be sent until a delay time called Inter-message gap. The
Inter-message gap depends on the baud rate and is calculated as shown below:
5 x 10
Ti =
b
Ti: Inter-message ga p [s]
b: Baud rate [bits/second]
Example
Inter-message gap at 9600 baud: Ti = 5 x 10 / 9600 ≈ 0.0052 s = 5.2 ms

If a Beijer Electronics RBC receives an SCOM message with a broadcast address from
the RS485 interface and the command is completed, the generated response message
is sent after a delay time. This is required, because many devices can be attached to
the RS485 bus, but only one device can claim the line for its communication. The
delay guarantees that each response message is sent one after one, even if all devices
have received the broadcast message and processed it at the same time, avoiding a collision on the RS485 bus.
The length of the delay time depends on the device address and maximum length of
a response message, and is calculated according to the following formula:
(2.5 + Lr) x 10 x N
Te =
b
Te: Bro ad cast command response [s]
Lr: Maximum length of response message
N: Device address + 1
b: Baud rate [bits/second]
10 Beijer Electronics, MAEN993
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 specifica tion is sent, the Lr value will grow accordingly.
Related information
Command Reference
Example
Broadcast command response for command BRT, sent by device with address 7 at
9600 baud: Te = (2.5 + 9) x 10 x 8 / 9600 ≈ 0.0958 s = 95.8 ms
The delay time Te is inserted by the device automatically, only if the RS485 interface
is selected for the communication. If the RS232 or USB interface is used, the response message is generated and sent as fast as possible.
The RS232 communication does not require a delay time due to the point-to-point
communication, where only two devices can be attached to the line (i.e. host and
Beijer Electronics RBC or Beijer Electronics RBC and Beijer Electronics RBC). USB
communication is similar to the RS485 communication, where many devices can be
attached to the same line. However, in contrast to the RS485 interface, a collision is
handled by the USB architecture and software, so there is no need for anti-collision
support within the device.

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.
Although each Beijer Electronics RBC is based on the same base firmware and uses
the same communication, some commands/sub-commands are hardware dependant
and not supported for each device of the series, due to the differences within the device hardware. These differences and required firmware versions are indicated in detail for each command description.
Note:
Response messages may be generated and sent back, even if the commands/sub commands are not supported within a particular firmware version or if they are invalid.

Command Reference
5.6 LAU
Lauer Extension
The Lauer Extension is a new SCOM command specially developed for Beijer Electronics RBC. It extends the standard SCOM command set with more powerful functions, which add special remote configuration, controlling and status capabilities to
each device.
The LAU command is a container for specific sub commands and their parameters.
They are encapsulated within the DATA field of the command stream. In contrast to
standard SCOM commands, a message returned in a response to Lauer Extension
command does not always contain the command itself. This means, a response message may contain the same data for different commands. Therefore, a response message should be processed immediately, after the command is sent.
The LAU command exposes the capabilities of a device model through SCOM.
While there is a base set of sub-commands, which are always supported on each device model, there are also sub-commands, which may expose the special capabilities
of a device, not available on other models.
The full LAU sub-command set is divided into three functional groups:
Group Purpose
CONFIGURATION Allows to query for or change the current device configuration.
CONTROL Intended to control a device or its hardware extensions, such as
buzzer, I/Os etc., during operation.
ST ATUS Used to query for the current device or hardware extension status,
such as IP address, buzzer stat e , analog/digital inputs etc.
For any LAU sub-command, the following command and response streams are generally common:

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.
This group may differ from the current display group. The group does not contain
address information.

Command Reference
5.6.26LAU_STATUS_SCOMSERMODE (0x0303)
Current SCOM Serial Interface Mode
The serial interface mode indicates the physical type of the serial interface used for
the SCOM communication. Available modes are RS232 and RS485. RS232 allows
point-to-point communication, i.e. computer and Beijer Electronics RBC or Beijer
Electronics RBC and Beijer Electronics RBC. With RS485, many devices can be attached to the same physical line and can be controlled by one or more computers,
allowing a kind of networking. Limitation is given only by the physical characteristics
of the RS485 bus.
This command returns the current serial interface mode. If the DIL switch settings
are used, this is the serial interface mode configured via DIL switch. If the DIL switch
settings are overridden, this is the software configured serial interface mode
