5.6 M-bus Interface for Consumption Data Capture
The M-bus (meter bus) is a fieldbus for the capture of e.g. gas, water or power consumption data. The data are
transmitted serially from the connected meters (slaves / field devices) to an M-bus gateway (master) on a
reverse-polarity protected twin wire cable. The M-bus gateway itself is connected to the COM2 interface of the
system centre.
Daily consumption values are recorded for each M-bus meter in the system at the factory. The daily
consumption values can be displayed in the menu 6-1. The option "Performance Calculation" must be set in the
menu 4-1-6 for the display of a load profile (consumed capacity in the last 15 minutes). The load profile can
then be displayed in menu 6-2.
Configuration of the measuring points
New measuring points connected to the M-bus are found using a scan process and included in the system. The
scan process is started in menu 4-1-6 using the following button:
If new measuring points have been found by the scan process, these are then displayed in the list and can be
configured

5.7 Alarms and messages
The system centre is the collection point for alarms and messages of all E*LDS components in the system. The
messages are listed in the alarm and message lists and can be called by the operator via Menu 1.
The alarm list provides a quick overview of all currently pending alarms; the message list shows the history of
the faults that have occurred and been rectified as well as all logged events. The alarm and message lists can
store 1000 entries. If the lists are full, the respective oldest entries are overwritten when new messages occur.
The messages in the list are in the order of their occurrence.
The generated messages of the E*LDS components are sent via CAN bus with one of the following priorities --,
0..99 to the system centre.
Priorities
Function
---
No message is generated, no alarm is signalled
0, 10, 20,...90
Lowest priority, message entry only in the message list, no alarm is signalled
1, 11, 21,...91
High priority alarm - entry in alarm and message lists, remote alarm is signalled, local
alarm is signalled (horn),
triggering of the alarm relay PRIO1, e.g. in the event of potential stock loss
It must be noted for GLT components in the 5000 family that configuration of a week timer is in fact
possible, but this remains
without function
