SIMOVERT MASTERDRIVES Compendium Motion Control 8.2-19
The parameter ID (PKE) is always a 16-bit value.
Bits 0 to 10 (PNU) contain the number of the required parameter.
Bit 11 (SPM) is the toggle bit for parameter change reports.
Bits 12 to 15 (AK) contain the task ID or the reply ID.
With regard to the task telegram (master → converter), the significance
of the task ID is given in Table 8.2-4. Task IDs 10 to 15 are specifically
for MASTERDRIVES and are not specified in the PROFIBUS-DP profile.
With regard to the reply telegram (converter → master), the significance
of the reply ID is given in Table 8.2-5. Reply IDs 11 to 15 are specifically
for MASTERDRIVES and are not specified in the PROFIBUS-DP profile.
Only certain reply IDs are possible, depending on the task ID. If the reply
ID has the value 7 (task cannot be executed), an error number is
deposited in parameter value 2 (PWE2) in accordance with Table 8.2-6.
