1. Product description
The CCLP-Modbus is a communication card designed to interface up to 4 Cristal
Controls relays scanners model CCLS-4016 within a low-voltage lighting relay
panel. With the CCLP-Modbus, CCLS-4016 are accessible from the Modbus
protocol. CCLP-1664 terminology indicates a complete relay panel.
Figure 1 - PCB CCLP-Modbus
When control by the Modbus protocol, it will allow access to inputs (4.1) and relay
outputs (4.2) through a list of “holding registers”. Relays can also be grouped
(4.3).

2. Typical wiring
These guidelines must be followed when the CCLP-Modbus and CCLS-4016
relays scanners are installed on site. Wrong wiring may damage the CCLP-
Modbus and the CCLS-4016.
2.1. Power Supply
The CCLP-Modbus controller and the CCLS-4016 relays scanners are half-wave
power supplies. Each controller needs a 24 Vac supply and polarity must be the
same on each controller. We recommend connecting the “negative” side of the
power supply to earth ‘’G’’ to comply with standards (such as CSA) or to make
sure the controllers have all the same reference.

2.2. Internal network (CAN)
The Modbus communication card retrieves states and sends commands to the
CCLS-4016 relay scanner. All CCLS-4016 relay scanner use a CAN Network.
This CAN network, needs to have a “bus” topology and 124-terminating
resistors at each end. Installing a jumper on the connector “Term” will enable the
network-terminating resistor. Wiring polarity must be respected on each
controller or communication failure will result and may also damage the CCLS-
4016 relay scanner.
Install jumper
for termination
Figure 3 - CAN terminating resistor
This CAN network cannot be extended outside the relay lighting panel, as the
extra wire length will decrease communication reliability.
Low capacitance cable for network communication such as Anixter 316-023-
1802-FR-05 or Cerco Cable AT-HOM29 must be used.

2.3. Ethernet IEEE 802.3
Ethernet, the CCLP-Modbus uses a standard CAT-5 unshielded twisted cable
with a RJ-45 connector. This is a dual-speed network communication card with
auto negotiation capabilities for any 10 BASE-T (10 MBits) or 100 BASE-T (100
MBits) connections.
The auto negotiation procedure does not well mix on 1000 BASE-T (1000 MBits)
connections. The CCLP-Modbus network communication card shall be set at the
same speed as the PC card in order to properly operate otherwise
communication will fail.
Cat5 cable length shall not exceed 100m (328 ft). When longer distances are
needed, refer to a specialized network partner to convert the network to
alternative media such as fiber optic, DSL, or wireless.
2.4. RS-485 Modbus RTU slave
Verify certain aspects when RS-485 Modbus RTU network option is selected.
When the CCLP-Modbus is at the end of a RS-485 bus, installing jumper “Term”
must activate the on-board 120-Ω terminating resistors. A 604-Ω biasing resistors
may be enabled by installing jumpers “Bias A(+)” and “Bias B(-)”.

3. Configuration console
The serial port of the CCLP-Modbus is used for the initial configuration of the
device. You can connect to the serial port using a standard straight DB-9 male to
DB-9 female serial cable. HyperTerminal can be used. Hyper Terminal is
available in most Microsoft Windows installations. If not available, you can
download the free PuTTY Terminal software or buy commercial software such as
EmTec ZOC terminal.
Communication parameters need to be at 115200 baud, 8 bits of data, no parity
and 1 stop bit. The computer needs to drive the DTR pin or the controller will
ignore any serial port communication.

the Modbus network and must be between 1 and 255. Follow this command with
a decimal number for the address to be used.
ModbusBaud
This command is to set RS-485 serial communication speed. Set the desired
baud rate. Available values are 9600, 19200, 38400, 57600, 76800, 115200, and
230400. Default value is 38400 baud this must be the same for all other devices
on the same RS-485 network.
ModbusDelay
This command is to set a delay to Modbus responses setting. The parameter
following this command is time (in milliseconds) with a default value of zero. It
can be useful to increase this delay to allow slower master controllers to receive
a complete reply.
ModbusCmdEvent
This command is to activate or deactivate event-driven commands. The
parameter following this command is ON or OFF. When activated the relays and
groups commands are executed each time. Deactivated the relays and groups
commands are executed only on change.

3.4. CAN
Redetect
This command forces the detection sequence for the CCLS-4016 relays
scanners on the CAN network. This is normally done during manufacturing and
is automatically done on power-up if no CCLS-4016 CAN addresses are defined
for the relays scanner. This command will overwrite CCLS-4016 addresses in
Modbus registers (4.4).
ShowCcls
This command displays an ASCII text file indicates firmware version information
of the CCLP-Modbus and the CCLS-4016 relays scanners. It also indicates if
some errors are detected from CCLS-4016 relay scanner communication side.
ClearLog
This command records all CCLS-4016 relay scanner events as seen on the CAN
network. All events can be wiped and restart with an empty log when activating
this command.
LogCan
You can control what type of CCLS-4016 relay scanner events will be recorded to
the flash memory. By avoiding some type of information you can record other
information for a longer period of time. Contact Cristal Controls if you need to
use the logging feature of the CCLS-4016 relay scanner. Default setting, ‘’no
message is being logged’’.
The recorded log can be retrieved from an HTTP file transfer.

schedule mode and apply command on the desired relays. Sub-commands
follow.
-initdelay : Set the used delay after a reset of the CCLP-Modbus. This
delay can be used to give more time to the master controller after a
power loss. If the master controller does not read the CCLP-Modbus
during this delay, we consider there is a communication problem.
masterctrl initdelay 900
OK
-delay : Set the inactivity delay for communication with the master
controller after the initial message has been received from it.
masterctrl delay 300
OK
-add/del on/off #relay: indicates if an ON or OFF command must be
applied after a communication with the master controller is lost. The
« del » command deletes the relay from the ON or OFF list. A relay
cannot be on both lists at the same time; when adding a relay to the
ON list, it is automatically deleted from the OFF list and vice versa.
masterctrl add on 10
OK
-del on/off #relay: removes a relay from the list of those needed to be
turned ON or OFF when communication is lost with the master
controller.
