IN0
Note:
If the firmware of DVPCOPM-SL is under V1.32, IN0 is invalid. But the function of IN0 is as below for the firmware of
V1.32 and above.
When IN0=ON and the master and slave make the connection, the master sends the NMT message (0x82 or 0x80)
first and then the SDO message. The interval time is 100ms between the two messages. The timeout for SDO
sending is 100ms.
When IN0=OFF and the master and slave make the connection, the master sends the NMT message (0x82 or
0x80) first and then the SDO message. The interval time is 1s between the two messages. The timeout for SDO
sending is 1s.
2.7 Digital Indicator
The digital indicator provides the following two functions:
Displaying the node address of DVPCOPM-SL.
Displaying the error message of slave.
