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. There are supported the The following object types are supported: digital input, digital output, analog input, analog output. There is required the installation Installation of the Advantech 32-bit driver (dll driver) is required. The driver versions 1.3 a 1.4 beta 4 were tested. In light of 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 in within 48 hours, required resetting 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 in 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.

Communication station configuration

...

• communication protocol: Advantech ADAM 5000 DeviceNet.
• Station The station address requires:
  • the number allocated assigned to the corresponding CAN channel of the PCL-841 841 interface ("CAN Device ID interface").
  • the number allocated assigned to the corresponding ADAM module - ("ADAM module ID"). These identification numbers are allocated assigned by the installation tool "Advantech IO Device Installation" installation tool. Numbers are allocated assigned from 000, 001, 002, etc.... .

I/O tag configuration

...

Possible I/O tag types : Ai, Ao, Ci, Co, Di, Dout.

The Ci and Co types allows allow reading of DI inputs or writing to DO outputs byte-by-byte (8 bits at once).

I/O tag address is the number of a corresponding I/O channel's number within the frame of the ADAM module.
