The protocol provides data input/output from the ADAM 5000 modules from the Advantech company via the CAN bus using the DeviceNet communication protocol. Communication requires the installation of the Advantech PCL-841 communication interface card. The following object types are supported: digital input, digital output, analog input, analog output. Installation of the Advantech 32-bit driver (dll driver ) is required. The driver versions 1.3 a 1.4 beta 4 were tested. Considering the long-term communication stability, it is recommended to use the version 1.4 beta 4 or later (March 2001), the version 1.3 was not successful on tests (communication had failed within 48 hours, reset of the ADAM 5000 system was required). Using the configuration tool Advantech IO Device Installation, it is necessary to define basic ADAM modules connected to the CAN network. The following table shows the list of ADAM modules, which are supported by the communication protocol. The modules ADAM 5051 and ADAM 5017 were tested.

The Ci and Co types allow reading of DI inputs or writing to DO outputs byte-by-byte (8 bits at once).
I/O tag address is the a number of corresponding I/O channel within the ADAM module.
