Communication with the Saphir regulator by the Siemens company
The
Saphir programmable universal regulators by the
Siemens company support multiple types of communication, depending on the regulator type (for example
ACX32, ACX34, ACX36, ACC88) and possibly on the types of add on cards.
Communication by the Modbus protocol
Some
Saphir regulator types (e.g.
ACX36) support the communication
by the Modbus protocol. For this communication in the PROMOTIC system can be used:
Communication via the OPC interface
The
ACX52.22 add on card has the Ethernet interface with implemented
OPC interface.
Then the PROMOTIC application will communicate as a client by the
OPC interface.
The usage
OPC (the
PmOpcUaClient communication driver or
PmaOpcDaClient object) requires purchase of the
"PmOPC" licence. When developing the application in the freeware mode
PmFree, or with
development environment and while testing it in runtime, this component is always functional.
Additional communication options
The
Saphir regulators and add on cards enable additional communication options For example:
- the KNX protocol (e.g. the ACX51.21 add on card).
- the
LON protocol (e.g. the
ACX51.25 add on card).
- the
BACnet protocol (e.g. the
ACX52.22 add on card).
