The number of plants is unlimited for all programs (ACS Operation, ACS Alarm, ACS
Batchjob and ACS Service). In the ACS programs, a plant is created for each central
unit.
In the ACS7… programs, data of all types of M-bus devices can be displayed and
downloaded. The data originate either directly from the M-bus device or from the cen-
tral unit, depending on the type of central unit used:
The OZW10 uploads certain data of the M-bus devices cyclically and stores them.
In the case of plants equipped with the OZW10, the data can either be uploaded di-
rectly from the M-bus device or from the memory of the central unit using the ACS…
The kind of data stored in the OZW10 depends on the type of M-bus device. An
overview is given in subsection 2.2.5 "Equipment combinations"
The OZW111 does not store any data from the M-bus devices. ACS7… always
uploads the data ("transparently") from the M-bus device
For the kind of data of the respective M-bus device available on ACS7…, refer to sec-
tion 8.6 "Data of M-bus devices available on ACS7… ".
With the operating software and the Batchjob software, the number of devices per plant
are limited. By contrast, with the alarm software and the service software, the number
of devices are unlimited. For limiting the number of devices, a credit is defined for each
standard package. Every connected device of the plant charges this credit with a de-
vice-specific value. The number of devices that can be served is limited by the credit
amount available. Additional credits can be ordered separately:
