1. Communication

2. Agenda 4-20mA / HART RS485 / Modbus GPRS 3DLinkPro / Modem Wizard
TCP/IP
DeltaV Connection
Barriers / Isolators for Explosive environment

3. Connection Methods
The 3D Solids Scanner can be connected to different systems for different purposes
4-20mA
A method of level/volume indication to a PLC or DCS system
HART
Using existing 4-20mA connection to transfer more data and allow a PC software to connect to a remote device
RS485
A serial, 2-wire, multidrop (“Daisy Chain”) communication protocol, works in a mode of one master-many slaves, with APM it is limited up to 64 scanners
Modbus RTU
Type of communication that utilizes the RS485 physical infrastructure

4. Connection Methods TCP/IP
Using a compatible RS485 to TCP/IP convertor, the 3D Solids Scanners can be connected to a local area network and be monitored by any computer connected to that network
APM recommends the use of BF-430 manufactured by CHIYU
Connecting the 3D Solids Scanner requires know-how and understanding of many terms and how they integrate together

5. 4-20mA The 3D Solids Scanner outputs an active 4-20mA
The Volume in percentage as defined by the full and empty calibration levels
The 4-20mA requires connection of a passive device on the other side for proper performance
The 3D Solids Scanner can be configured to output 4-20mA  0%-100% or 20-4mA  0%-100%
For testing purposes, the 3D Solids Scanner can simulate any current level between 4mA to 20mA in resolution of 0.01mA

6. 4-20mA + HART
The 3D Solids Scanner can be controlled via the 3D Vision using the 4-20mA output
A MicroLink HART modem is recommended for use with the 3D Solids Scanner
HART Baud rate is 1.2kbps
Max cable distance: 3km (2miles)
View only – not fully HART compliant
Connection example of 4-20mA + HART

7. Multiple Scanners Using 4-20ma Output Only
Point to Point Connection

8. RS-485 Serial communication method
One device is a master
All other devices are listening and replying on demand
Each node on the bus has a unique address (polling address) between 00 to 63
Masters can be connected on the RS-485 bus using a communication converter, such as GSM modem, TCP/IP converter, USB, RS-232, etc.
Cable requirements:
Shielded, Twisted-pair, 120 Ohm impedance

9. RS-485 Resistors must be at the far ends of the RS-485 bus
When two or more power supplies are in use, it is recommended to use mutual ground
Cable grounding shield must be connected to the ground on one end of the cable
Max Cable distance: <1000m (~4000 ft.)

10. Daisy Chain connection up to 64 scanners

11. GPRS using 3DLinkPro
Using 3DLinkPro to convert the RS485 data into TCP/IP packet and transfer it over GSM network
SIM card must be activated and compatible with GPRS, and allow sending and receiving of SMS messages
Recommended data quota/plan for at least 150MB/month in constant connection
Before using the 3DLinkPro it is advised to test the SIM card with the 3DLinkPro in-house before shipping (using the APM Modem Wizard)
SIM #, APN name must be obtained
Disable any PIN code / Username and Password
Preferable to have a fixed IP for the SIM card
Note: one of the scanners must have polling address 00

12. GPRS Topology

13. GPRS using 3DLinkPro
Steps for connecting the 3D Solids Scanner to the 3D Vision:
Open the 3D Vision and start a communication to the specified phone number using GPRS option
Send SMS to the 3DLinkPro:
e.g.: CALLAPM, ,7040,internet,
Wait for connection
Note: In order to make the connection, in the local network, a port forwarding option must be activated to the computer’s local IP Address

14. 3DLinkPro –Connection

15. Modem Wizard Fill required fields under “Modem Details”
Press “Analyze!”
Results appear in “Analyzed Info”
If all fields are filled, communication is ok and ready for connection

16. TCP/IP Connection
It is possible to convert the RS485 serial bus to a TCP packet and transfer it over Local Area Network (LAN) using a compatible device
APM recommends to use model BF-430 manufactured by CHIYU

17. TCP/IP
Setup example

18. TCP/IP Important notes:
The BF-430 must be assigned with a static IP Address
Local Firewall on the computer must be configured accordingly
APM strongly recommends to advise the local IT personnel of the specific configuration or privileges that might be needed to configure the BF-430

19. Modbus (RTU)
RS485 Serial communication method designed for industrial devices for controlling and monitoring
Using standard Modbus commands the measure data can be received by the connected controller
Note: When using Modbus (via the RS485) it is possible to derive the registers in parallel to the 3D Vision connection
Relevant Registers: to 40026

20. Connection to DeltaV Unable to use existing 3D MultiVision software
Fastest value update rate; approximately every 10 seconds
Least complex setup; connection is directly to DeltaV Serial card

21. Connection via VIM Card through 3D MultiVision Server
Values update slower than previous configuration; approximately every 45 seconds
3D MultiVision Server must be running for DeltaV to read values
Any configuration changes to DeltaV or VIMNet require a server restart
Able to use 3D MultiVision Server & Client simultaneously with DeltaV

22. Explosive Installations
ATEX II 1/2D Ex iaD/ibD 20/21 T110C
FM CL I,II Div I GP CDEFG
NEPSI
For explosive areas, the customer is responsible to install the scanner according to the local guidelines
