9.5 PT113CO – CANopen
After setting related parameters (address in the Gatway tab of AzComT 6.3.4.4 or with the
programming switch 5.1.3), communication with the indicator via a CANopen network is possible.
9.5.1.1 EDS File
A sample EDS file is provided to assist with PLC interfacing. This should be tailored by the PLC
programmer to suit the specific application.
9.5.1.2 CANopen Interface
The interface is described in 5.1.2.6. In summary it has automatically detected and supported baud
rates of 10 kbps, 50 kbps, 100 kbps, 125 kbps, 250 kbps, 500 kbps, 800 kbps, 1 Mbps and Autobaud
(default).
There are 2 LED’s near the CANopen connector which are Error and Run above and below the
CANopen connector respectively, with meanings as below.
