CJ1W-PNT21 PROFINET IO Controller DTM
Valid Output Data Handling

/i
The Valid Output Data Handling Box defines the behaviour of the PROFINET
IO Controller Unit on the PROFINET network in case a PLC mode change
occurs. Check boxes define how the Unit should behave in case the PLC
mode is changed from RUN / MONITOR mode to PROGRAM mode, or vice
versa.
/i
The PROFINET IO Controller uses for this the Provider Status field in the
PROFINET Output Data message. This Provider Status field is set valid or
invalid by the Producer. The Consumer will interpret the Provider Status field.
If the Provider Status field is set to invalid the Consumer will discard the
received Output data. For more information about Provider Status field and the
Output Data status see Appendix A.
At startup the PROFINET IO Controller configures the relations with the
PROFINET IO devices. The PROFINET IO Controller will query the IO devices
by name. After finding the PROFNET IO Device on the network the
PROFINET IO Controller will issue an IP address to the IO device. This IP
address will be used to configure the relation between the PROFINET IO
Controller and the IO Device.
The following settings must be entered:
•
•
•
•
The Device Name entered must be equal to the name that was given to the IO
Device in the network Scan in the PROFINET Identification screen. If there is
a mismatch the IO Controller can not establish a connection. The name
entered in the Network Scan is not automatically copied to the IO Device
Setup list.

The IO Controller DTM performs the I/O data mapping by
allocating the I/O data in ascending order of IO Device
address and selected I/O modules. Memory allocation gaps
will be optimised for efficiency.
New I/O modules are appended to the existing mapping.
Changed I/O modules will be re-allocated to the end of the
list. This may create gaps in the memory allocation.
The PROFINET IO Controller will mark its output data as
invalid when the PLC is in Program mode. When the PLC is
in Run/Monitor mode the PROFINET IO Controller will mark
the output data as valid.
The PROFINET IO Controller will mark its output data as
invalid when bit 12 in the Software Switches 1 word is OFF.
When bit 12 in the Software Switches 1 word is ON the
PROFINET IO Controller will mark the output data as valid.
The Software Switches 1 word is located at address
1500 + (25 x Unit number).
