Data integrity
Integral data is data that always has to be transmitted between the higher-level
controller and the MOVI-PLC
®
advanced
DHF41B control card as one block and must
never be transmitted separately.
Data integrity is particularly important for transmitting position values or complete
positioning tasks. The reason that data integrity is so important is that data which is not
transmitted integrally could come from different program cycles of the higher-level
controller, which would lead to undefined values being transmitted to MOVI-PLC
®
advanced
DHF41B controller.
For PROFIBUS DP, data communication between the higher-level control and the
MOVI-PLC
®
advanced
DHF41B control card is carried out with the setting "Data
integrity over entire length".
TIP
The MOVI-PLC
®
advanced
DHF41B control card does not support the "Special
identifier formats" coding! Only use the setting "Integrity over entire length" for data
transmission.
