Operands
| Operand | Description |
|---|---|
| S | The first operand. Entries are WORD data registers or constants. This is the value to convert to 7-segment code. The value range is H0000 ~ HFFFF. |
| D | The second operand. Entries are only DWORD data registers. This is where the 7-segment code is saved. |
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.
Instruction Behavior
The SEG and SEGP instructions behave as follows:
- Converted data is stored in D and D+1.
- It is possible to express arabic numerals (0\~9) and alphabets (A\~F).
- The 160‘s place of the conversion result is stored in the lower byte of the data register D.
Ladder Diagram Examples
SEG
The SEG instruction converts a Hexadecimal value, S, into 7-segment code representation. The conversion is saved in an assigned data register, D.
When the contact, M0.0 is ON (1), the instruction converts the data register, D0, into 7-segment code. The result is saved in D2.
Memory Monitor
SEGP
The SEGP one-shot instruction converts a Hexadecimal value, S, into 7-segment code representation. The conversion is saved in an assigned data register, D. Every time this instruction executes, it energizes the output only once.
When the contact, M0.1 is ON (1), the instruction converts the data register, D5, into 7-segment code. The result is saved in D7.
