Modbus platform entities are configured within the Modbus configuration. To write a float32 datatype register use network format like 10.0 = 0x41200000 (network order float hexadecimal). Restart communication (Stop first if running) These services will not do any reconfiguring, but simply stop/start the modbus communication layer. The Modbus integration also provides communication stop/restart services. Array will call modbus function code 0x0F Single boolean will call modbus function code 0x05. (write_coil) A single boolean or an array of booleans. E.g., to set 0x0004 you might need to set, this depend on the byte order of your CPU Array will call modbus function code 0x10. Single value will call modbus function code 0x06. (write_register) A single value or an array of 16-bit values. Hub name (defaults to ‘modbus_hub’ when omitted) The Modbus integration provides two generic write services in addition to the platform-specific services. Remark: name:is required for multiple connections, because it needs to be unique.

# Example configuration.yaml entry for multiple TCP connections Multiple connections are possible with identical/different type. I would say to be of much practical use in a Modbus environment, the per-slave poll setting would be very desirable.Type of the connection to Modbus, needs to be serial for this setup. OH2 does provide a general way to invoke a poll from a rule by sending a “dummy” REFRESH command, but the particular binding needs to support the REFRESH action. There is not going to be a way to invoke a poll in OH1.

If a device don't answer after 3 polls then do something.Īnother example ( a real): my zwave device which command my pool pump is offline, if not an interactive poll … As an alarm rule is on, 3 polls are done every minute on all listed devices. Example: someone try to use a jammer on your zwave sensor. It could be usefull when you wants to know if your zwave devices are functionnal. Zwave Feature Needed : polling a zwave device from a rule BindingsĪs There are fast dev for OH2, I wanted to know where could I ask this feature. Xyz.rule: … sendCmd (item, NULL) … which fires a call rather then send real command. Modbus.cfg: … poll = 0 or NULL … which indicates a ‘manual’ firing The execution should then be done asynchronously. is firing this function every second (poll=1000), to trigger it within a rule or a hubpanel script (e.g.

But rather it is used by a timer, which e.g. In the current implementation there is a function within the Modbus binding which periodically reads one or more registers from a Modbus slave. What I’d like to suggest is very very simple. I’m not talking about read-only requests nor about things which touches OH philosophy. If you issued a ‘read’ from a rule, I’m not sure its within OH philosophy to wait for a response (or failure) from the device before carrying on with the rule? OH’s event-driven structure doesn’t lend itself well to a read-on-request strategy.
