Read Set Point examples (Modbus function 03H):
Error codes:
Parameter Acyclic
Write Operation
(Modbus function 10H)
The DP-V1 addressing principle defined for reading operations is applicable for parameter
acyclic writing. The only difference is that set point data address must be added to 1000H.
Write Set Point examples:
The following sequence must be followed to issue a parameter set command when
security is enabled.
Any rejected message, considering a valid address was defined, is answered with “Writing
error” status.
When a valid password is received by the device, it enables the associated access level for
5 minutes. It’s disabled automatically after this period. Also, it can be disabled when
master issues a 0000H password entry.

Profibus DPV1 Error Code
Cause
Invalid slot
Wrong code was added to the slot. Ensure 3000H or 4000 was added
to the memory map address issued to the device.
Invalid index
An invalid memory area was defined. It can be caused by a base
invalid memory address or a request to read a reserved memory area.
Ensure the base address is correct and that a valid length was
specified.
