Vendor telegram 860
With this telegram it is not necessary to set special bits for a cyclic data
transmission� In its functionality, it is similar to PROFIBUS and provides for easy
configuration of the preset value during PLC operation� The velocity value uses the
format that is defined in the velocity measuring unit�
If bit 31 is set to "1", the preset value will be adopted immediately� A further preset
value can only be set if bit 31 is reset to "0"�
●
No control word
●
No status word
●
No status indication
●
Output: 32 bit-unsigned preset value (bit 31 preset control, must be less than
total resolution)
●
Input: 32 bit-unsigned preset value + 32 bit-integer velocity value
Data input (from encoder to controller): 8 bytes
Position value - 32-bit unsigned
Velocity value - 32-bit signed
