Chapter 8 – Communication Trace Example

CHAPTER 8 COMMUNICATION TRACE EXAMPLE

The following is an example of a typical communication session with MultiLoad starting with host system

startup, driver card in, transaction authorization, batch authorization, end of batch processing, and host system

shutdown.

Upon startup it is recommended that the host system verify as many parameters as practical to avoid

problems during loading due to mis-configuration. If any parameters are different then expected the

discrepancy should be logged and startup should be aborted. Recommended parameters to check are:

Firmware Version

Configured bit is set.

Remote Processing is enabled.

Number of configured presets.

Number of meters, components and additives for all presets.
