If you connect a HSM plus BSM to a Logamatic 5000, it is automatically integrated
as slave10 in the Logamatic 5000. A possible second, third, ... HSM plus BSM is in-
tegrated accordingly as slave11, slave12,… .
2.7.2.1 Access to Substation
All data points can be retrieved via the master using Modbus TCP. Since the ad-
dresses of the data points may differ depending on the system structure, you can
use the following formulas to calculate the corresponding addresses:
First you have to calculate the required offset for the respective slave (10 - 15):
You can now add this offset to the addresses of the HSM plus BSM. The result is
the address of the data point with which you can access the respective BSM via the
master.
Example:
You want to retrieve the address "Input Register 1 - Own Flow Temperature" from
slave11 via master.
2.7.2.2 Access to substation via segment substation
You can also access the substations of an HSM plus BSM (Slave10 - Slave15) via
the master. For this you must also first calculate the offset and then add this with the
address.
You can now also add this offset to the addresses of the respective HSM plus de-
vice. The result is the address of the data point with which you can access the re-
spective HSM plus device via the master.
Example:
You want to retrieve the address "Input Register 34 - HMI State" from slave 1 via
slave10 of the master:
You can access the HMI State of slave station 1 of segment slave station 10 via the
head-end station using the address "Input Register 10034".
