GLM Supported Tank Gauging Protocols
The following is a list of currently supported communication protocols:
1. Serial Port Communication - RS232 (Serial)
- Datasound53 - Receives ASCII text broadcast data, (UME/Rolls-Royce Marine AS).
- AN-PRO3 - Receives ASCII text broadcast data (Ariston Norway protocol).
- Sentry IV - Receives ASCII text broadcast data (Consilium US protocol).
- Modbus - Receives broadcast data using function code 16 in RTU transmission mode (with additional options for sending acknowledgments & volume data).
- Musasino – Receives ASCII text broadcast data from Musasino Co, Ltd.
- NMEA 0183 - uses a simple ASCII, Serial communications protocol.
- NCA DL-94 MSI - Kongsberg Serial communication Interface.
2. Ethernet Communication
- VIGO - Receives fieldbus management system data (PROCES-DATA protocol).
- Modbus TCP
3. Text File Communication
- Bergan - Receives sounding information updated in a shared text file.
- TextFile - Receives data periodically updated in a shared comma-delimited text file, with one line per sensor, each line starting with the sensor ID.
4. Command Communication
- Command - Processes LOAD commands from a run file written by a user-provided external program executed by the SI system.
Other tank gauging interfaces may be made available upon request and given full protocol specification details
Other tank gauging interfaces should be doable so long as full specifications are provided and the gauging system supports either (1) ASCII data broadcast over a serial port, or (2) writing of tank dat
a to a text file (with the text file method preferred for being more foolproof and easier to troubleshoot).
In order to evaluate the feasibility and time-frame for a new tank gauging system in a GLM, the customer must first provide:
(1) the software interface specification for the tank gauging system, and
(2) a technical contact who can knowledgeably answer questions regarding this specification.
Note: the interface specification required is for communications protocol between the gauging system and external programs such as GLM, and is not for internal interface between the gauging system and
its physical tank gauges.
Once Creative Systems has evaluated this specification and all technical questions have been answered, Creative Systems will provide an estimated time-frame needed for implementing the GLM interface to the customer.
Once the GLM interface software is ready, a minimum of two (2) weeks prior to ship's departure should be allowed after installing GLM software to troubleshoot any tank gauging issues that may arise.
During this period, the customer must provide a knowledgeable on-site technical contact who will work directly with Creative Systems in a timely manner (either by email or phone during regular Creative
Systems business hours) to diagnose and correct any installation issues.
The options in the GLM_Maker wizard which are related to tank gauging systems are located under Options\Tank Gauging and Options\Buttons\Tank Buttons
As always, please ask if you have questions after you have looked at the options in the GLM_Maker and obtained specifications for the tank gauging system.
