3.4.6 The Data Field

The structure of data blocks depends on the type of telegram. There are three telegram types, and the type applies for both
control telegrams (master

⇒

slave) and response telegrams (slave

⇒

master).

The 3 types of telegram are:

Process block (PCD)
The PCD is made up of a data block of 4 bytes (2 words) and contains:

Control word and reference value (from master to slave)

Status word and present output frequency (from slave to master)

Parameter block
The parameter block is used to transfer parameters between master and slave. The data block is made up of 12 bytes (6
words) and also contains the process block.
