Parameter Change Logbook; Event Logbook - RMG EC 900 Operating Instructions Manual

CONSTRUCTION AND FUNCTION
..........................................................................................................................................................................................................
Information (clear text, only transmitted via Modbus)
Source of change (e.g. keyboard, COM1, optical interface)
Checksum for the data record (CRC)
* The device itself will display the address of the Modbus register. When calling data via DSfG-B,
the data element identifier will be transferred with the relevant parameter.
Source of change:
0 Change via control panel
16
1 Change via data interface 1 (optical interface on the front)
2 Change via data interface 2 (RS 232 or RS 485)
The memory depth is 600 entries.

Parameter change logbook

All parameter changes are recorded in this logbook. It is organized as a circulating buffer as usual:
new entries overwrite older ones. The structure is identical to that of the legal metrological log-
book. Entries made in the legal metrological logbook are once again archived here.

Event logbook

Device-internal messages and events are stored in the event logbook. This is not done in clear text
but by using message numbers (see table "Fault messages"). Positive numbers stand for coming
events, while negative numbers stand for going events.
