SERCOS interface
6.5.5 Representation of the ATs in the PCLrho4.0
The following pictures show an example of the SERCOS axis telegrams
on the PCL.
In the symbol file of the PCL program, 640 bytes in the I/O area of the
PCL are reserved. The number 640 bytes results from:
22 Byte AT per axis * 24 axes = 528 Byte
Reserve = 108 Byte
rho4.0 system counter = 4 Byte
=> Number of the bytes
to be transmitted =
640 Byte
