3.1
RS485 - X / Protocol:
Communication protocol of RS485-X port.
3.2
RS485 - X / Address:
Network address of the RS485-X port. (Available for Sitrad and MODBUS protocols).
3.3
RS485 - X / Baud rate:
Communication data rates (Available for the MODBUS protocol only).
3.4
RS485 - X / Parity:
Communication protocol parity (Only available for MODBUS protocol).
3.5
RS485 - X / Stop bits:
Number of stop bits (Only available for the MODBUS protocol).
18.3.1 Communication with Sitrad:
Communication with the Sitrad Pro software follows the following network structure:
For more information access: www.sitrad.com
0 = Sitrad (Available for RS485-1 port only)
0 = 4800
0 = no parity
3 = 38400
1 = MODBUS
1 = 9600
1 = even parity
1 = 1 stop bit
4 = 57600
2 = 19200
2 = odd parity
2 = 2 stop bits
5 = 115200

18.3.2 Communication MODBUS:
The
RCK-862
plus
is compatible with the standard MODBUS-RTU protocol. For information on the implemented commands and registration table,
contact Full Gauge Controls (e-mail:
or phone: (51) 3475-3308).
18.4 Expansions:
The
RCK-862
plus
has the possibility to expand the number of inputs and outputs using expansion modules. This feature allows you to control more
complex systems, increasing the number of controlled devices and expanding the possibilities for monitoring and protecting the system.
Through the Exp communication port it is possible to connect up to ten expansion modules, gradually expanding the options of inputs and outputs
available to the existing logic. It is recommended to use cables with screens / shields and minimum diameter of 24AWG or (0.5mm) for communication
between the expansions and the module.
For example, when using and RCK-461 expansion module, 8 more digital outputs (5 STPS and 3 SSR), 2 0-10V analog outputs, 6 dry contact digital
inputs and 8 configurable analog inputs for sensors (NTC or 4-20mA) are added.
To enable communication between the
RCK-862
plus
and the expansion modules, you must configure the desired module in Expansion Model
address 1 to 9 (
4.1
a
4.9
) and assign the same address to the expansion module. Each expansion module must have an address between 1 to 10,
without repeating an address.
