Eaton Electrical EZ204-DP user manual Control commands for EZ700

6 Control commands for EZ700

Data exchange procedure The “Control commands 9 bytes” module allows extended data exchange of the EZ700 on the PROFIBUS-DP communication bus. This allows you to transfer services from the following areas:

•Read/write image date and time (Page 45)

•Read/write image data (Page 49) and

•Read/write function block data (Page 72).

A data exchange procedure is required in order to ensure the safe exchange of data via PROFIBUS-DP from master to slave and vice versa.

Attention!

While a control command is being executed, the input and output data will remain in the state before the control command was called. Only after the “Control commands” data exchange has been completed, will the I/O data be refreshed.

Caution!

Only those values specified for the command code should be used.

Check the values that you write in order to avoid malfunctions.

Requirement:

The “Control commands 9 byte” module must have been selected.
