Supported device types and versions

The protocol allows reading and writing data into the Advantech ADAM series 4000 devices.

Types of usable I/O tags according to ADAM type are listed in the following table:

Table 1

Type and range of measurementsADAM device typeRead/Write
1 x analog input AI4011, 4011D, 4012, 4013, 4014D, 4016R
8 x analog input AI4017, 4018, 4018M, 4019R
1 x analog output AO4021R/W
4 x analog output AO4024R/W

Communication line configuration

Required line parameters:

Communication station configuration

  • Communication protocol: Advantech ADAM Series 4000
  • Station address – Module Address - ADAM module address (according to the setting of modules in configuration), a number in the range of 0 to 255 specified either as a decimal number or a hexadecimal number with a hash at the beginning (e.g. #1A).
  • Time parameters – polling parameters – for optimal and quick communication - Delay 0 seconds (all stations).

Station protocol parameters

Configuration dialog box - tab „Parameters".
They influence some optional parameters of the protocol.

For further information on protocol parameters, see the topic Communication line - configuration dialog box.

I/O tag configuration

I/O tag address requires two parameters:

  • Channel - number of ADAM module channel, a number in the range of 0 - 15 (for ADAM module with one channel, use Channel = 0), specified either as a decimal number or a hexadecimal number with a hash at the beginning (e.g. #A).

The following table represents the configuration of channels for individual types of ADAM modules:

4052, 40688 x DI0 up to 7
4051, 405316 x DI0 up to 15

Reading and writing of analog inputs and outputs are supported for the “Engineering units” data format.
