### **Triggering the transmission of Modbus data**

The data transmission is triggered if at least one of the following conditions described below is met:

Requirement: A suitable array is connected at the input `ariInputArray` connected. This is indicated by the output `xInputArrayValid` (= TRUE).

1. after an edge change at the input `xUpdateSetp` (FALSE >> TRUE) (once)
2. after the elapsed time `tTimeUpdateSetp` (`tTimeUpdateSetp` > 0) (cyclic)
3. after a change in the array at the input `ariInputArray` (data type, size, contents) (once)
4. after a change of essential parameters (`byUnitId`, `wRegisterAddr`) (once)
5. after an edge change at the input `xEn` (FALSE >> TRUE) (once)
6. after each cold start (once)

Note: The data type of the array at the input `ariInputArray` cannot be detected and evaluated as of 07/07/2023 (CDS-43675 Compiler, AnyType: Extension for Arrays needed) In the tool tip help for the input `ariInputArray` the possible array data types are displayed depending on the selected function code.
