Multiple data such as measured values of the Main Units are periodically sent to the specified area of
the PLC. The K6PM-TH can perform tag data link communications over four connections.
• PLC-side input tag set
The I/O memory address or variables are assigned. The data sizes of the four segments are 128 bytes,
380 bytes, 380 bytes, and 418 bytes (K6PM-TH internal data sizes), for a total of 1306 bytes.
• Main Unit-side output tag set
The Main Unit assigns the instance ID of the internal data to be tagged data link. The data sizes are 128
bytes, 380 bytes, 380 bytes, and 418 bytes for a total of 1306 bytes.
Configuration Tool
When configuring with OMRON controllers, the following setting tools for the tag data link should be
used.
A CIP client such as the NJ/NX-series issues any CIP command in the Explicit message to the Main
Units. This allows you to read and write all the data of the Main Unit.
Communications Instructions
When sending a CIP command with Explicit messages from OMRON PLCs or Controllers, use the
following communications Instruction.
