How to detect the communication status of Motionnet in a program?
After opening the Master card, initiate a mechanism to poll the Motionnet Ring status. The flowchart is as follows:
Command Descriptions:
1._mnet_get_ring_error_counter
This API provides a numeric value that continuously increases up to the maximum value of 65535 in case of communication abnormalities. In contrast, during normal communication, the value remains unchanged
Format
I16 status=_mnet_get_ring_error_counter(U16 RingNo, U16*ErrCount)
Purpose
Get the value of ring communication error counter.
Parameters
Name | Type | Description |
RingNo | U16 | Motionnet Ring number |
ErrCount | U16* | The Value Of Ring Communication Error Counter |
Status Return
Function Name | Description |
ERR_NoError | The API Is Succes Return |
ERR_Invalid_RingNo | Make Sure The Ring Is Active |
Command Descriptions:
2._mnet_reset_ring_error_counter
This command is primarily used to reset the error count
Format
I16 status=_mnet_get_ring_error_counter(U16 RingNo)
Purpose
Reset the ring communication error counter.
Parameters
Name | Type | Description |
RingNo | U16 | Motionnet Ring number |
Status Return
