Operands
| Operand | Description |
|---|---|
| Base/Slot | The first operand. Entries are Hexadecimal data registers or constants. This is the base and slot number where the positioning module is located. This location depends on the amount of expansion modules the chassis contains. If the CPU supports positioning, refer below. |
| S | The second operand. Entries are WORD data registers or constants. This is where the control data is stored. The value range is 0 ~ 2. |
| D | The third operand. Entries are only WORD data registers. This is where the result of the operation status is stored. |
Assignment Example
The following example shows how to assign values to Base/Slot.
Module/Slot (PLC-AES/ES)
| Module | Slot | Example |
|---|---|---|
| CPU | Slot 0 | H0000 or 0 |
| 1st Expansion | Slot 1 | H0001 or 1 |
| 5th Expansion | Slot 5 | H0005 or 5 |
| 10th Expansion | Slot 10 | H000A |
| 15th Expansion | Slot 15 | H000F |
PLC-AES/ES CPU
If the CPU module is a PLC-AES or PLC-ES CPU, assign H0000 to Base/Slot.
S
| Value of S | Description |
|---|---|
| 0 | Initializes both parameters and positioning data in flash memory. |
| 1 | Initializes only parameters in flash memory. |
| 2 | Initializes only positioning data in flash memory. |
D Data Register Result
| Result Type | Bits | Description |
|---|---|---|
| Error Code | H00 | No error |
| Error Code | H10 | Incorrect positioning control data |
| Error Code | HFF | Instruction not supported |
| Operation Status | Bit 0 | 1 when the instruction executes |
| Operation Status | Bit 1 | 1 when instruction execution finishes |
| Operation Status | Bit 2 | 1 when an error occurs Simultaneously sets with Bit 1 |
| Operation Status | Bit 3 ~ 7 | Reserved |
Notice
Error Flag (F11.0) Notice
The error flag, F11.0, will be ON for one scan when the address of the data register assigned by @D exceeds the range of the data register, D. The range of the data register, D, is dependent on the CPU type.
Execution Condition
It is recommended that the PINIT instruction be used with a pulse contact as an execution condition.
Ladder Diagram Examples
PINIT
The PINIT instruction initializes positioning parameters and/or positioning data for flash memory and saves the result in an assigned WORD data register, D.
When the contact, M1.6 or M1.7, is powered ON (1), the PINIT instruction initializes the positioning data and/or parameters for flash memory.
The result of the initialization is saved in the data register, M1460.
