8.3 Programming SIDOOR instructions
PROFINET or PROFIBUS SIDOOR controllers are configured via certified GSD files. This
ensures compatibility with different industrial automation systems. A function block is
provided for fast and simple interfacing of a SIDOOR drive to a SIMATIC. This function block
was implemented for PROFIBUS or PROFINET communication and for various SIMATIC
families. The blocks always operate in accordance with the principle described below.
Figure 8-1
The SIDOOR function block handles the data processing of exactly one SIDOOR controller.
Therefore the block has to be called with a data instance for each SIDOOR bus node. There
are no restrictions on the call cycle of the SIDOOR function block. A cycle time of >10 ms is
recommended to make optimal use of the resources.
The selected SIDOOR bus node is localized by specifying a hardware address ID. Every
time the function block is called, the control data is transferred to the controller according to
the "SIDOOR_CDat" structure. Additionally, the current status data is updated in accordance
with the "SIDOOR_SDat" structure. The availability of the SIDOOR bus node is also
checked, and the node diagnostics data is updated. A parameter job is acyclic, and is
processed during the course of several call cycles of the SIDOOR function block. The block
returns the result and the status of the parameter job. The block number can be changed.
Response to errors
If communication and/or the block is interrupted (ERROR ≠ 0000
follows:
● No parameter job is accepted.
● The states of the output parameters PKW_REPORT and PKW_FAILED remain
unchanged.
● All control data (CDAT) is rejected.
● All elements of the SDAT status data structure are set to 0.
