THE CONCEPT BEHIND THE INTEGRATED
ANALYZER/SAMPLING SYSTEM IS TO USE WHAT
IS AVAILABLE TODAY IN TERMS OF FLUID
CONTROL/SENSING TECHNOLOGY AND THE
CURRENT I/O WITHIN THE ANALYZER
IF THE DEVICES ARE DIGITAL OR ANALOG
MULTIVARIABLE (SUCH AS HART), THEN USE THE
MULTIVARIABLE INFORMATION, IF THEY ARE
SIMPLY ANALOG, USE THE ANALOG
INFORMATION
ALL OF THIS INFORMATION AND CONTROL CAN
BE UTILIZED VIA CONVENTIONAL DCS OR HMI

SAM Specifics
Communication module on the CIM76 is pre-certified for the
appropriate bus selection
CIM76 with Industrial Ethernet (Ethernet IP, Modbus TCP) has the
following











Java web server
FTP server
Email server for alarming
IS CIRCOR iCAN or CANopen interface
4 channels of analog input and 24VDC excitation for use with std IS shunt-diode
barriers and IS certified analog sensors
Need C1D2 certified power for 24VDC and C1D1 certified 9V power for IS
CANbus
Allows for required galvanic isolation between haz location zones and
additional isolation from PLC, Data logger, or DCS
Manages bus timing arbitration (i.e. CAN repeater functions) between
low speed CAN in IS Zone and high speed CAN, Ethernet, Profibus DP
Has capabilities to send down alarms, commands, set points down to
CAN devices and send alarms and data up to a “bus master” thru
mailbox

SAM Specifics
Currently used as CAN Repeater and Bus Gateway



CIM76 Module has enough low-power processing
capability for much more value added functions
Investigating the need for additional RTOS (Real time
operating system)







Bridge the gap between PLC and Sample system
Bridge the gap between C1D1 zone and C1D2 zones
Embedded OPC server utilizing CANopen EDS sheets from sample
system devices
JAVA web server can serve up system as built configuration with
dynamic web data from sample system devices, including some basic
analog 4-20mA
Inventory of all CAN devices
Password protection
Problem: Very few plant IT infrastructures would allow a
link to a field device via ethernet

Points for Discussion
Discussion points:









Would CIM76 module ever need to communicate to DCS
directly?
If so, could it connect via Ethernet or serial bus, or discreet
digital I/O
Where does the CIM76 module sit on the network?
Does the CIM76 need to be accompanied by a PLC? If so, how
would it communicate with the PLC?
Does the device require its own programming interface, GUI, or
programming port? Ethernet modules would have their own IP
address and also have a web interface that would allow
visualization and a possible configuration interface.
Inventory of everything on the bus?
What happens with error detection, power loss, component
change out situations?
OPC server?
