: data = read (dev, target, address)

: data = read (dev, target, address, count)

: data = read (dev, target, address, count, serverId, precision)

Read data from modbus device dev target target starting at address address.

Inputs

dev - connected modbus device

target - target type to read. One of ’coils’, ’inputs’, ’inputregs’ or ’holdingregs’

address - address to start reading from.

count - number of elements to read. If not provided, count is 1.

serverId - address to send to (0-247). Default of 1 is used if not specified.

precision - Optional precision for how to interpret the read data. Currently known precision values are uint16 (default), int16, uint32, int32, uint64, uint64, single, double.

Outputs

data - data read from the device
