Omron PROFINET IO Controller Unit is a CPU Bus Unit, which can be installed on a CJ1 PLC System. The CJ1W-PNT21 controls the data exchange between PROFINET IO Devices and a CJ1 PLC system over a PROFINET IO network. For an overview of the PROFINET IO technology refer to Appendix A PROFINET IO Technology.

| I/O data allocations | Maximum total size: 7168 words. I/O Data can be allocated to up to 2 input and 2 output areas. Input and output areas can be mapped to CIO, DM, WR, and HR areas, as well to EM banks. Mapping must be defined through the configuration software. |
|
| FINS Messaging | Reading IO Device Alarm | The MEMORY AREA READ FINS command can be used to obtain the last received IO Device Alarm message. |
| Reading and controlling the error log |
Catalogues the history of error events. The Unit supports the following Error Log related FINS commands: • ERROR LOG READ • ERROR LOG CLEAR |
|
| FINS Services | FINS/UDP | Supported Maximum packet size is 1500 bytes |
| Other functions | Error history size and storage | The PROFINET IO Controller Unit supports storage of up to 80 error events, including time stamps, in volatile memory. 16 error events can be logged in non-volatile memory. |
| Memory Card backup function | Allows PROFINET IO Controller Unit’s Configuration to be backed up as a file to a Memory Card in the CPU Unit. The backed up configuration data can later be restored from the Memory Card into the PROFINET IO Controller Unit. |
