I-7242D 
DeviceNet / Modbus RTU Gateway |
|
|
|
|
|
|
|
| |
|
|
| |
The I-7242D is
one of CAN bus products in ICP DAS. The device allows a master
located on a DeviceNet network to enter into a dialogue with the
slaves on a Modbus RTU network In DeviceNet network, it is a
|
|
Group 2 Only Slave device, and supports “Predefined Master/Slave
Connection Set”. It is a general protocol converter operating
in a way that is transparent to the user. In addition, we also
provide the utility software for users to configure the I-7242D，s
parameters and build the EDS file. Users can easily apply Modbus
RTU devices in DeviceNet applications with the I-7242D. |
