5.12FB1 Control Program
It is now possible to generate the control program with the completed blocks.
Task:
In our sample program, two command strings with two requests each will be processed.
With the START_SLG1 (I0.0), the command chain of the first reader is executed.
First, the MDS status information will be read, and then a write command is carried out on Reader1. With Reader1, we write 8 bytes that are stored in DB48 starting with DBB0 to the MDS. With the RESET_SLG1 (I0.1), the error is reset if there is an error (LED at Reader1 flashes red) and a “init_run command“ to reset the first reader is executed.
With the RF300_ISO (I02), switching between MDS types (for example RF360T) or ISO transponder (for example, Moby D ISO) is to be carried out on the first reader (RF310R).
With the START_SLG2 (I1.0), the command string of the second reader is executed.
First, the MDS diagnosis information will be read and then a read command will be executed at Reader2. With Reader2, we read 8 bytes from the transponder and then write them to DB48 starting with DBB50.
With RESET_SLG2 (I1.1) the error is reset if there is an error (LED at SLG2 flashes red) and a “init_run command“ is executed to reset the second reader.
In addition, the attendance time of the transponders is to be recorded on the readers.
