DCON protocol
is a kind of application protocol based on the RS-485 network.
It is special for ICPDAS DCON I/O modules, such as I-7000 series
and I-87K series modules. By way of using I-7231D to convert the
electric signals and messages, the DCON I/O modules can be upgraded
to the CANopen protocol based on the CAN bus. For CANopen protocol
application, the I-7231D is a CANopen slave device. So, it can
produce or consume the PDO messages, receive the SDO message with
proper responses, and deal with the NMT messages from NMT master.
For DCON protocol application, it is a DCON master device, and
it will collect all of the I/O situations of the I-7000 and I-87K
series modules connected with the RS-485 port of I-7231D. Therefore, If the I-7231D receive the command form CAN bus, it does the corresponding reactions for
DCON I/O channels. In addition, we also provide the utility tool
for users to configure the device parameters and build EDS file
for the CANopen slave device. Therefore, users can easily apply
I-7k and I-87K IO modules in any CANopen master interface via the EDS file.
