Firmware Version 3/4.31.37
2.2 SYSTEM OVERVIEW
The MultiLoad II is designed to manage multiple loading arms delivering straight or blended products. The
system can operate in conjunction with the Toptech TMS system (remote processing mode), in Local
(standalone) mode or connected to the cloud (UAP Mode). The MultiLoad II supports:
12 loading arms
5 meters per loading arm, 6 component ratio blending.
8 components per loading arm, 8 components sequential blending.
Sequential, Ratio and Side-stream blending.(proportional as non-proportional blending)
Watercut calculation
16 additive injectors per loading arm
4 samplers per loading arm
Digital, two stage, and Analog 4-20mA control valves

2.3 THREE OPERATING MODES
The MultiLoad II can be configured to operate in three different modes:
Local (stand-alone) Control Mode –product and access information are stored in non-volatile memory in the
MultiLoad II.
Remote Control Mode –access and product information is controlled by TMS or another remote computer
system.
UAP –Interfacing with a host-system in the cloud which has all basic TAS functionality.
2.3.1 LOCAL CONTROL MODE
In local mode, the MultiLoad II RCU will read a driver’s Prox Card (Excluding the SMP) or will prompt the driver to
enter an access ID. Next the driver will be prompted to enter a PIN code. The supplied driver card or access ID
and PIN must match a record in the driver database stored in the non-volatile memory of the MultiLoad II RCU.
Once verified, the MultiLoad II will act upon its internal configuration regarding additional prompts. The MultiLoad
II has up to 5 configurable prompts that may be presented to the driver. Once these data entry prompts have
been recorded, loading will be authorized.
Capabilities of the MultiLoad II operating in Local mode are:
- 300 access ID’s and associated PIN codes.
- 10,000 transaction archives complete with salable product, component detail and additive detail.
- 5 user-configurable custom prompts; resultant data stored with each transaction.
- 33 product recipes per meter/loading arm.
- Meter Ticket –combined ticket for all transaction liftings in user-configurable format.
- Meter, Additive, and Temperature Calibration features.
- Log of the last 1000 Weights and Measures parameter changes. Also stored on the sd-card for 90 days.
- Config Change Log of the last 500 parameter changes included W&M parameters. Also stored on the sd-
card for 90 days.
- Log of the last 500 configuration changes in the Auditlog.
2.3.2 REMOTE CONTROL MODE
When interfaced to a remote computer system, the number of driver records, customer prompts and recipes is
virtually unlimited.
2.3.3 UAP MODE
This is an interface to the cloud and has all basic functionality of a TAS-system in the cloud.
