1. Select instruction
This item selects the ZRN instruction to use from ZRN1 or ZRN2.
The output differs by the instruction.
2. S1 (source 1): Control register
S1 specifies the starting number of the data registers to use with the ZRN1 or ZRN2 instruction. 
Starting from the specified number, 3 continuous words of data registers are used. 
The range of available data register numbers is D0 to D997 and D1000 to D1997.
3. S2 (source 2): Initialization input
S2 specifies the initialization input. When the initialization input S2 is turned on, the initial values configured in the WindLDR ZRN
instruction dialog box, on the
Setting tab, are stored in the control registers. An external input (I0 to I35) (Note) or an internal
relay (M0 to M1277) can be specified.
When the initialization input is on, the initial values are written to the data registers with each scan. To only initialize the values
one time, use the initialization input in combination with the SOTU (single output up) instruction or the SOTD (single output
down) instruction.
Note: For the 40-I/O type, external inputs (I0 to I27) can be used.
