The protocol allows reading and writing data into the Advantech ADAM series 4000 devices.
Types of useable usable I/O tags according to ADAM type are listed in the following table:
...
- Communication line category: Serial, SerialOverUDP Device Redundant.
- Transfer parameters (Baud rate, number of stop bits, speed, number of bits, and parity bitesbits) according to the setting of ADAM modules.
- Other parameters see the Communication line - configuration dialog box.
...
- Communication protocol: Advantech ADAM Series 4000
- Station address – Module Address - ADAM module address , decimal number in range of 0 up-to 255 (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).

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

| Using the checksum. Set according to the setting of module ADAM in the configuration. | YES/NO | YES |
For further information on the protocol parameters, see the topic Communication line - configuration dialog box.
...
- Channel - number of ADAM module channel, decimal 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).
