Version 5.2.x

Protocol

• Where a request takes one of several alternative parameters, a key set to null is treated as if it was omitted, see the protocol specification.

New requests

• setCounterValues sets counter values without changing their configuration.
• getEncoderQuadInvert and setEncoderQuadInvert get and set whether the encoder direction is reversed.
• Modbus values (v5.2.1): listModbusValues, getModbusValue, setModbusValue, and waitModbusValue.
• getLabelBitmap (v5.2.4) renders a label to a black and white PNG at a given resolution. It is also available as a REST endpoint.

Changed requests

• All delete* requests accept an array of names to delete several items in one request: deleteClock, deleteCounter, deleteImage, deleteLabel, deleteNumberFormat, deleteShiftCode, deleteTable, deleteTimeFormat, and deleteVariable.
• setCounters keeps the current value and repeat state of a counter when value is omitted.
• The image state returned by getImageInfo and listImages is PARKED for images that are not active.

GPIO

• Photocell triggers are exposed as read-only conditions named device.<device>.TRIGGER<n>, see Input/output.
