Industrial Electronic Devices
If the "DLR" and/or "DLW" has got the value 0x00 there are no data to read/write.
The "Data IN" are the same that the HD67576-A1 sends.
The "Slave informations" (Byte 4 of all frames) gives informations about the slave interrogated. Every bit has a meaning:
•
Bit0: Configuration corresponds;
•
Bit1: Parameters OK;
•
Bit2: Configuration OK;
•
Bit3: Data OK.
If all is correct, you have to read 0x0F.
Example of communication between HD67576-A1 connected to a HD67575-A1 through Ethernet and a slave PROFIBUS connected to the
HD67575-A1. The Slave has got 7 OUT and 3 IN:
