20.3 FNC152 – TBL / Batch Data Positioning Mode
Outline
This instruction executes one specified table operation from the data table set in GX Developer (Ver.8.23Z or later).
→ For explanation of the instruction, refer to the Positioning Control Edition manual.
→ For cautions on using special high speed output adapters,
refer to the Positioning Control Edition manual.
*1. This function is supported only in FX
3U/FX3UC PLCs.

*2
.
*1. Y002 is not available in 14-point and 24-point type FX
3G PLC.
*2. High-speed output special adapters can be connected only to FX
3U PLC.
*3. To use Y002 and Y003 with a high-speed output special adapter, connected a second high-speed output
special adapter.
Points
• When using a relay output type FX3U PLC, a special high speed output adapter is required.
• Outputs of special high speed output adapters work as differential line drivers.
