RKC INSTRUMENT FB400 Series Use and care manual

Digital Controller
IMR01W07-E4
This manual describes the connection method with host computer, communication
parameters and communication data (except for parameters in Engineering Mode) of
the FB400/FB900. For detailed host communication such as communication data in
the Engineering mode, protocol and Modbus data mapping description, refer to the
FB100/FB400/FB900 Communication Instruction Manual (IMR01W04-E).
The Communication Instruction Manual can be downloaded from the official
RKC website: http://www.rkcinst.com/english/manual_load.htm.
1. OUTLINE
Digital Controller FB400/FB900 (hereafter, called controller) interfaces with the host
computer via RKC or Modbus communication protocols. In addition, there is the
Modbus data mapping function which enables high-speed communication by
collecting only the data to be communicated at all times in the specified address area.
Communication port
There are two communication ports: Communication 1 and Communication 2.
Communication 1 is used for host communication.
Communication 2 is used for intercontroller communication, but can be also used for
host communication.
When Communication 2 is used for host communication, refer to the FB100/
FB400/FB900 Communication Instruction Manual (IMR01W04-E).
Communication interface
Communication 1 interface: RS-422A, RS-485, RS-232C
Communication 2 interface: RS-485
(When Communication 1 is used for RS-422A, no
Communication 2 can be used.)
2. WIRING
Make sure that lugs or unshielded cables of the communication
terminals are not touched to the screw heads, lugs, or unshielded cables
of the power supply terminals to prevent electric shock or instrument
failure. Use additional care when two lugs are screwed to one
communication terminal.
The cable and termination resistor(s) must be provided by the customer.

ANSI X3.28-1976 subcategories 2.5 and A4).
For the COM-K, refer to the COM-K Instruction Manual (IMR01Z01-E).
3. SETTING
To establish communication parameters between host computer (master) and
controller (slave), it is necessary to set the device address (slave address),
communication speed, data bit configuration and interval time on each controller
(slave) in the Setup setting mode.
After all communication parameters are set, in order to make these
values thus set valid perform any of the following operations.
The power is turned on again after turning it off once.
The RUN/STOP mode is changed in RUN from STOP again after
changing it in STOP once.
Parameters which are not related to existing functions on the controller are
not displayed.
This instrument returns to the PV/SV monitor screen if no key operation is
performed for more than one minute.
This section describes the parameters which must be set for host
communication. For the screen operation and key operation, refer to the
FB400/FB900 Quick Operation Manual (IMR01W02-E).

Interval time 1 * 0 to 250 ms The interval time for the controller
should be set to provide a time
for host computer to finish
sending all data including stop
bit and to switch the line to
receive status for the host.

* The interval time for the controller should be set to provide a time for host computer
to finish sending all data including stop bit and to switch the line to receive status for
the host. If the interval time between the two is too short, the controller may send
data before the host computer is ready to receive it. In this case, communication
transmission cannot be conducted correctly.
